Preface
This article is about X Sir, I have a brief look these days Python Inside wxpy After module , collocation matplotlib A module written by wxpy Basic usage , Mainly used wxpy Carry out a series of automatic operations on wechat , Such as the use of wxpy Login WeChat 、 Send message to wechat file assistant 、 Send a message to a single wechat friend 、 Wechat message group sending ( Use caution [/ Evil smile ]) And the construction and use process of wechat chat machine , Do you think wxpy Only such ？No, Last X Sir, take advantage of wxpy Got the number of my wechat friends 、 Gender 、 Nickname and personal signature , WeChat official account 、 Official account information , collocation matplotlib A series of data visualization is carried out , Mixed in the middle X Mr. Zhang's analysis of some staggering words , From these ,,, I read out a real me （ Positive solution at the end of the paper ）.

One 、wxpy Basic introduction and installation

1.wxpy Basic introduction

wxpy be based on itchat, Used Web Wechat communication protocol , Through a large number of interface optimization to improve the ease of use of the module , And expand the functions . Wechat login is realized 、 Send and receive messages 、 Search for friends 、 Data statistics 、 WeChat official account 、 WeChat friends 、 Wechat group basic information acquisition and other functions .
It can be used to realize the automatic operation of various wechat personal numbers .

2.wxpy install

Method 1 ： Direct installation

pip install wxpy

Method 2 ： Douban source installation （ recommend ）

pip install -i https://pypi.douban.com/simple/  wxpy

Two 、 True knowledge comes from practice

1. Send a message to your file transfer assistant

from wxpy import *
#  Initialize a robot object 
bot = Bot(cache_path=True)
#  Send message to file transfer assistant 
bot.file_helper.send("hello,I'm XksA!")

Bot Introduction to basic parameters of class ：

cache_path –
     Sets the cache path for the current session , And enable the cache function ; by  None ( Default )  The cache function is not enabled .
     After the cache is enabled, repeated code scanning can be avoided in a short time , When the cache fails, the login will be required again .
     Set to  True  when , Use default cache path  ‘wxpy.pkl’.
qr_path –  Path to save QR code 
console_qr –  Display login QR code in terminal 

A QR code picture will pop up after running , Just log in with wechat scanning code , Come back and see the mobile phone news .

* Special reminder ：* The wechat account used cannot be a newly registered account , Otherwise, it will report a mistake KeyError: 'pass_ticket'.

2. Send a message to a designated friend

#  Initialize a robot object 
# cache_path Cache path , The given value is the cache file path generated by the first login 
bot = Bot(cache_path="H:\PyCoding\Wxpy_test\wxpy.pkl")
#  Find friends " The minimalist XksA"
my_friend = bot.friends().search(' The minimalist XksA')[0]
#  Send a message 
my_friend.send('hello  The minimalist XksA!')
'''  In addition, you can send the following content , Try it yourself   Send pictures  my_friend.send_image('hello.png')  Send video  my_friend.send_video('hello.mp4')  Send a file  my_friend.send_file('hello.rar') '''

Running results ：

3. Group-sent message （ I woke up this morning with a whim , Send everyone a good morning ！）

import time
#  Initialize a robot object 
# cache_path Cache path for login status , The given value is the cache file path generated by the first login 
bot = Bot(cache_path="H:\PyCoding\Wxpy_test\wxpy.pkl")

#  Group-sent message （ Use caution , Ha ha ha ）
my_friends = bot.friends(update=False)
my_friends.pop(0)   #  Remove the first element of the list （ own ）
for i in range(120):
	friend = my_friends[i]
	friend.send('Good morning,the early bird catches the worm!( Good morning , The early bird catches the worm ！)')
	time.sleep(2)
	friend.send(' Don't reply , Refueling together in life ！')

Running effect ：

4. Get the number of your wechat friends 、 Number of active wechat groups 、 WeChat official account

#  Get all your friends [ Return list contains Chats object ( All your friends , Including myself )]
t0 = bot.friends(update=False)
#  View your friends ( Get rid of yourself )
print(" Number of my friends ："+str(len(t0)-1))

#  Get all wechat groups [ Return list contains Groups object ]
t1 = bot.groups(update=False)
#  View the number of wechat groups ( Active )
print(" My wechat group chat ："+str(len(t1)))

#  WeChat official account for all concerns [ Return list contains Chats object ]
t2 = bot.mps(update=False)
#  WeChat's official account of concern 
print(" My official account of WeChat public ："+str(len(t2)))

Running results ：

#  notes ： If you just take t0、t1、t2 Print out the corresponding name ( Different types of , You can try it yourself )
 Number of my friends ：242
 My wechat group chat ：6
 My official account of WeChat public ：125

5. Construction of personal chat robot （ self-based ）

#####（1） Own chat robot

#  Find chat objects 
my_friend = bot.friends().search(' The minimalist XksA')[0]
my_friend.send('hello  The minimalist XksA!')

#  Automatic recovery 
#  If you want to reply to all your friends, set the parameters  my_friend  Change to  chats = [Friend]
@bot.register(my_friend)
def my_friednd_message(msg):
	print('[ receive ]' + str(msg))
	if msg.type != 'Text':   #  Message reply content other than text 
		ret = ' What did you show me ！[ please ]'
	elif " Where are you from? " in str(msg):   #  Answer specific questions 
		ret = " I come from minimalism XksA"
	else:         #  Text message auto answer 
		ret = ' I love you! '
	print('[ send out ]' + str(ret))
	return ret
#  Enter interactive  Python  Command line interface , And block the current thread 
embed()

#####（2） Chat renderings

6. Construction of personal chat robot （ Based on Turing robot ）

#####（1） preparation
Click here Sign up for a Turing robot account , Then create a robot , You can get your Turing robot api.

#####（2） Create your own chat robot

• Method 1 ： Use Tuling class , Simple implementation

#  Login cache path , Set to... For the first time True
#  Generate cache file wxpy.pkl after , Is the path to the file 
bot = Bot(cache_path="H:\PyCoding\Wxpy_test\wxpy.pkl")  
tuling = Tuling(api_key=' Your Turing interface api')
print(' The minimalist robot has started ')
#  My trumpet , Caution in testing 
my_friednd = bot.friends().search(' The minimalist XksA')[0]
#  If you want to reply to all your friends, set the parameters my_friend Change to chats = [Friend]
#  Use Turing robot to automatically chat with designated friends 
@bot.register(my_friend)
def reply_my_friend(msg):
    tuling.do_reply(msg)
#  Enter interactive  Python  Command line interface , And block the current thread 
embed()

• Method 2 ： Send it manually post request , A little trouble hahaha ~

def auto_ai(text):
	url = "http://www.tuling123.com/openapi/api"
	api_key = " Your Turing interface api"
	payload = {
    
		"key": api_key,
		"info": text,
		"userid": " cousin "
	}
	r = requests.post(url, data=json.dumps(payload))
	result = json.loads(r.content)
	return "[ Minimalist robot ] " + result["text"]
	
bot = Bot(cache_path="H:\PyCoding\Wxpy_test\wxpy.pkl")  
print(' The minimalist robot has started ')
#  My trumpet , Caution in testing 
my_friednd = bot.friends().search(' The minimalist XksA')[0]
#  If you want to reply to all your friends, set the parameters my_friend Change to chats = [Friend]
@bot.register(my_friednd)
def my_friednd_message(msg):
	print('[ receive ]' + str(msg))
	if msg.type != 'Text':
		ret = ' What did you show me ！[ please ]'
	else:
		ret = auto_ai(msg.text)
	print('[ send out ]' + str(ret))
	return ret
#  Enter interactive  Python  Command line interface , And block the current thread 
embed()

#####（3） Chat renderings
Basic test , Turing robot can query the weather 、 ticket 、 translate 、 Basic chat and other functions , Than we wrote ourselves , strong ,,, Ha ha ha .

7. Have some fun

(1) Get wechat friend gender 、 Location distribution data

''' author :  The minimalist XksA data : 2018.8.26 goal :  Get wechat friend gender 、 Distribution 、 Wechat nickname , Visual analysis  '''

from wxpy import *

#  Initialize a robot object 
# cache_path Cache path , The given value is the cache file path generated by the first login 
bot = Bot(cache_path="H:\PyCoding\Wxpy_test\wxpy.pkl")
# Get a list of friends ( Including myself )
my_friends = bot.friends(update=False)
''' stats_text  function ： Help us simply count the basic information of wechat friends   Text of simple statistical results  :param total:  The total number  :param sex:  Gender distribution  :param top_provinces:  Province Distribution  :param top_cities:  City Distribution  :return:  Statistical result text  '''
print(my_friends.stats_text())

(2) utilize Matplotlib Data visualization

1） Gender pie chart

from pylab import *
mpl.rcParams['font.sans-serif'] = ['SimHei']
#  The above two lines of code solve the problem matplotlib The drawing cannot display Chinese 
import matplotlib.pyplot as plt

labels = [' men ', ' women ', ' other ']
sizes = [57.1, 32.2, 10.7]
explode = (0, 0.1, 0)

fig1, ax1 = plt.subplots()
ax1.pie(sizes, explode=explode, labels=labels, autopct='%1.1f%%',
        shadow=True, startangle=90)
#  Vertical and horizontal equality , Draw a circle 
ax1.axis('equal')
plt.legend()
plt.show()

design sketch ：

My god （ owner-draw ）, My wechat friends are actually mostly men , Hey , It's normal , I never flirt , Of course, there are not too few girls hey , Including family, friends and some social people Hey .

2） Urban distribution bar chart

import numpy as np
import matplotlib.pyplot as plt

n_groups = 10
#  Urban distribution quantity weight 
city_weight = (10.2,8.98,8.57,2.04,2.04,1.63,1.63,1.22,1.22,1.22)
fig, ax = plt.subplots()
index = np.arange(n_groups)
bar_width = 0.35
opacity = 0.4
error_config = {
    'ecolor': '0.3'}
rects1 = ax.bar(index, city_weight, bar_width,alpha=opacity, color='b', error_kw=error_config,label=' City ')
ax.set_xlabel(' The city name ')
ax.set_ylabel(' Data share (%)')
ax.set_title(' Friend City Top10')
ax.set_xticks(index + bar_width / 2)
ax.set_xticklabels((' jingzhou ', ' wuhan ', ' Yellowstone ', ' haidian ', ' Guangzhou ',' Shenzhen ', ' huanggang ', ' Hangzhou ', ' Changsha ', ' Changping '))
ax.legend()
fig.tight_layout()
plt.show()

design sketch ：

It is easy to see from the figure X Sir, many friends are in Jingzhou , Guess what X Where are you from, sir ？ you 're right , It's from Jingzhou hey , Are you also home to the most people among your friends ？（ Suddenly homesick ！）

3） Distribution map of friend provinces

from pyecharts import Map
# matplotlib The method is troublesome , It doesn't show up yet pyecharts  good , Just used it. pyecharts 
value = [359.2, 65.3, 49.0, 20.4, 20.4, 16.3, 16.3, 12.2, 12.2,12.2]
attr = [
    " hubei ", " guangdong ", " Beijing ", " hunan ", " Shanghai ", " Zhejiang ", " Henan ", " anhui ", " Shandong "," fujian "
    ]
map = Map(" Friends distribution Province Top10", width=600, height=400)
map.add(
    "",
    attr,
    value,
    maptype="china",
    is_visualmap=True,
    visual_text_color="#000",
)
map.render()

design sketch ：

Is it very straightforward , My friends are basically in central and southern China , Do you know the distribution of your friends ？ I'm in the middle and lower reaches of the Yangtze River , There are water and mountains here , There are flowers and grass , There is a paradise .

4） Get friends' wechat nicknames and personal signatures , Word cloud analysis

bot = Bot(cache_path="H:\PyCoding\Wxpy_test\wxpy.pkl")
# Get a list of friends ( Including myself )
my_friends = bot.friends(update=False)
#  Wechat nickname 
nick_name = ''
#  Wechat personal signature 
wx_signature = ''
for friend in my_friends:
	#  Wechat nickname ：NickName
	nick_name = nick_name + friend.raw['NickName']
	#  Individuality signature ：Signature
	wx_signature = wx_signature + friend.raw['Signature']

nick_name = jiebaclearText(nick_name)
wx_signature = jiebaclearText(wx_signature)
make_wordcloud(nick_name,1)
make_wordcloud(wx_signature,2)

design sketch ：

My wechat friend nickname , It's a little complicated. , Taobao , Hao Hao , stone , And Entrepreneurship , Of course, the most striking is the teacher , They say the teacher is a gardener , Thank you for raising us （ Sudden sense ）.

I found that they can practice into a paragraph ： All our lives , Is the greatest ordinary self , Meet a beautiful self , Life is more than life , come on. ...

5） Get attention to the name and basic introduction of WeChat official account , Word cloud analysis

#  Get the name of WeChat official account 
wx_public_name = ''
#  Brief introduction of official account 
wx_pn_signature = ''
#  Get WeChat official account list 
my_wx_pn = bot.mps(update=False)
for wx_pn in my_wx_pn:
	wx_public_name = wx_public_name + wx_pn.raw['NickName']
	wx_pn_signature = wx_pn_signature + wx_pn.raw['Signature']

wx_public_name = jiebaclearText(wx_public_name)
make_wordcloud(wx_public_name,3)
wx_pn_signature = jiebaclearText(wx_pn_signature)
make_wordcloud(wx_pn_signature,4)

design sketch ：

See anything strange ？ You ask me how much I love you , You look at Python I know. Ha ha ！

It can be seen that I pay attention to the positive , Excellent , The official account of technology people should be public. （ The minimalist XksA[ To laugh ]）, Hey ,Java,Python, English , data , Reptiles …

3、 ... and 、 an account of happenings after the event being told

summary
Visualize the results from the data above , I speculated that I ：X sir , Wechat nickname old watch , Gender male , Coordinate address: Jingzhou, Hubei , Most of the friends are men , It shows that you are ambitious , There are also many women , It shows that women are also good , Wechat friend's personal signature is basically positive , Yes life , Yes struggle , Yes like , WeChat official account is most technical related. , Focus on Python, Sometimes I play half heartedly Java, It should be a college student , Also concerned about the official account of universities. ...
