User interaction + formatted output

用户交互

1 2 3 4 5 6 7	`#!/usr/bin/env python` `#__coding:utf-8__` `#name = raw_input("What is your name?") #only on python 2.x` `name` `=` `input``(``"What is your name?"``)` `print``(``"Hello "` `+` `name )`

输入密码时,如果想要不可见,需要利用getpass 模块中的 getpass方法,即：

1 2 3 4 5 6 7 8 9 10	`#!/usr/bin/env python` `# -- coding: utf-8 --` `import` `getpass` `# 将用户输入的内容赋值给 name 变量` `pwd` `=` `getpass.getpass(``"请输入密码："``)` `# 打印输入的内容` `print``(pwd)`

       
       # 使用getpass模块中的功能,先导入进来,但是getpass在PyCharm中不起作用,Need to enter to the console
       
import getpass
       
username = input("username:")
       
password = getpass.getpass("password:")
       
print(username, password)

用户交互+格式化输出_python

Use the console can showgetpassModule function below：

用户交互+格式化输出_python_02

chmod 755 hello.py(加入权限755:7-->4:读取+2:写+1：执行,User can read write executable is belong to.5：4+1)

755 ：所属用户、所属组、其他用户

       
       # !/usr/bin/env python
       
Tell the system used by the interpreter：envIs the system environment variables when the executable program automatically find executablePython路径,此处不要写死！！！

       Use code print multiple lines
      
1.

       
       msg = """username = input("username:")
       
password = input("password:")
       
print(username,password)"""
       
print(msg)

　　实现：

　　　　username = input("username:")
　　　　password = input("password:")
　　　　print(username,password)

注意：shellThere is a difference between single and double quotes in the

       
       input的使用如下：
       
username = input("username:")
       
password = input("password:")
       
print(username,password)

　　实现：

　　username:123
　　password:123
　　123 123

注意：能不使用“+”Plus stitching will not use,太占内存了.

       
       There are three kinds of the formatted output format

       # 格式化输出方式一：
       
name = input("name:")
       
age = int(input("age:"))
       
job = input("job:")
       
salary = float(input("salary:"))
       
info = '''
       
------info of %s
