pip换源app 实现

话不多说直接上代码

from PyQt5.QtWidgets import QWidget, QApplication, QComboBox, QPushButton
import sys

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

    def setup_ui(self):
        self.resize(500, 100)
        self.setWindowTitle("更改pip源")
        # 实例化QComBox对象
        self.cb = QComboBox(self)
        self.cb.resize(320, 30)
        self.cb.move(90, 10)
        # 添加条目
        self.cb.addItems(["清华镜像源", "阿里巴巴镜像源", "豆瓣镜像源", "中国科技大学镜像源", "山东理工大学镜像源", "华中理工大学镜像源"])
        # 信号
        # print(self.cb.currentText())
        self.cb.index = 0
        # 返回选中项文本
        # print(self.cb.currentIndex())
        # 返回选中项索引
        self.cb.currentIndexChanged.connect(self.print_v)  # 条目发生改变,发射信号,传递条目索引
        # 清华索引0,阿里索引1,豆瓣索引2,中国科技大学3,山东理工大学4, 华中理工大学5
        # 添加按钮
        self.submit = QPushButton(self)
