?实现多线程

代码如下

import sys
import time
from PyQt5 import uic
from PyQt5.QtCore import QThread
from PyQt5.QtWidgets import QApplication, QWidget
class MyThread(QThread):
    def __init__(self):
        super().__init__()
    def run(self):
        for i in range(5):
            print("是线程中执行...%d" % (i+1))
            time.sleep(1)
class MyWin(QWidget):
    def __init__(self):
        super().__init__()
        self.init_ui()
    def init_ui(self):
        self.ui=uic.loadUi('./bun.ui',self)
        lineedit=self.ui.lineEdit
        btn1=self.ui.pushButton
        btn2=self.ui.pushButton_2
        # 绑定槽函数
        btn1.clicked.connect(self.click_1)
        btn2.clicked.connect(self.click_2)
    def click_1(self):
        for i in range(5):
            print("================= 卡的线程  =================中执行...%d"%(i+1))
            time.sleep(1)
    def click_2(self):
        self.my_thread=MyThread()
        self.my_thread.start()
if __name__ == '__main__':
    app = QApplication(sys.argv)
    mywin = MyWin()
    mywin.ui.show()
    app.exec()
