Pyqt based grouping tool

be based on PyQt Grouping tool

Function description ： Group the existing student list , As a result, groups appear .

（ It is similar to drawing lots and grouping

Why should I do this ：

• A friend needs to organize a competition , Need to put 16 People are divided into 4 Group , But the organizer doesn't want the results of the four groups to come out at the same time . It needs to be displayed in groups .（ Why ？

• However, geese's current small program is crisp, and directly displays the results of grouping .

• So I simply wrote this grouping tool . Follow up optimization of custom grouping .

One 、 Group core code writing

1、 Code

import random

#  Member list 
list_stu = ["01", "02", "03", "04", "05", "06", "07", "08", "09", "10", "11", "12", "13", "14", "15", "16"]
#  Sort the list by random number function 
random.shuffle(list_stu)
n = 4  #  Divide into n Group 
m = int(len(list_stu) / n)  #  Number of members per group 
list_fz = []  #  Create a group list 
for i in range(0, len(list_stu), m):
    list_fz.append(list_stu[i:i + m])
#  Loop through the nested list 
for i in range(len(list_fz)):
    print(" The first %d Group list :" % (i + 1), end=" ")
    for stu in list_fz[i]:
        print(stu, end=" ")
    print()
print()

2、 Running results

Two 、GUI Interface grouping code writing

1、 Code

import sys
import random

from PyQt5.QtWidgets import QMainWindow, QPushButton, QApplication, QLabel, QMessageBox
from PyQt5.QtWidgets import QDesktopWidget
from PyQt5.QtCore import Qt


class Example(QMainWindow):

    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):
        self.resize(1000, 500)
        #  Set title 
        self.setWindowTitle(' Grouping tool ')
        #  Set center 
        self.center()

        #  Create button 
        btn1 = QPushButton(" grouping ", self)
        btn1.move(450, 400)
        #  establish label
        self.label_1 = QLabel(self)
        self.label_1.move(100, 50)
        self.label_1.resize(800, 50)
        fz = "<p style='line-height:50px; width:100% ; white-space: pre-wrap; font-size: 35px; '>  Grouping  </p>";
        self.label_1.setText(fz)
        self.label_1.setAlignment(Qt.AlignCenter)
        self.label_2 = QLabel(self)
        self.label_2.move(100, 100)
        self.label_2.resize(800, 250)

        #  Define global variables 
        global count
        global list_fz
        global members
        global n

        #  Loop through the nested list 
        for i in range(len(list_fz)):
            print(" The first %d Group list : " % (i + 1), end=" ")
            for stu in list_fz[i]:
                print(stu, end=" ")
            print()
        print()
        count = 0
        members = ""

        btn1.clicked.connect(self.buttonClicked)
        self.statusBar()
        self.show()

    def center(self):
        qr = self.frameGeometry()
        #  Get the size of the main window 
        cp = QDesktopWidget().availableGeometry().center()
        #  Get the resolution of the display , Then get the position of the middle point 
        qr.moveCenter(cp)
        #  Then put the center point of your window on qr The center of 
        self.move(qr.topLeft())

    def buttonClicked(self):
        global count
        global list_fz
        global members
        global n
        count += 1
        if (count > n):
            msg_box = QMessageBox(QMessageBox.Information, ' error ', ' You have finished grouping ！！')
            msg_box.exec_()
        else:
            members += ' The first ' + str(count) + ' Group list :'
            for stu in list_fz[count - 1]:
                members += stu
                members += ' '
            members += '\n'

            self.label_2.setText(membersShow)


app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())

2、 Running results

• Click group to start grouping , When the grouping is over, click Yes to pop up “ Group complete ” Prompt box for .
  
• Click to group into a list .
  

3、 ... and 、 take .py The file is packaged as .exe Executable file

Can be in pycharm Medium terminal Input in , You can also enter cmd Go to the command line

1、 download pyinstaller

pip install pyinstaller -i https://pypi.tuna.tsinghua.edu.cn/simple/

2、 pack

-F It is used to package all supporting files , Do not display other dependent files

-w Hide the black window of background control during the process of program operation

-n Appoint Executable file name

-i icon.ico Yes, it will be under the same directory icon.ico The file is set to the execute file icon

 pyinstaller -w -F python file name .py -i  Icon name .ico

Four 、 summary

I haven't touched before PyQt, Yes python The basic knowledge is not very reliable . The content is also very simple , No special thinking . Hope to make more progress in the future .
