用我做的那个 eventlet-pyqt 可以这么玩。

$ sudo zypper in python3-eventlet python3-qt5
$ git clone https://github.com/hgoldfish/eventlet-pyqt.git
$ cd eventlet-pyqt
$ vi testwin.py
$ python3 testwin.py

import time  # Used as a sleep timer.
from PyQt5 import QtCore, QtGui
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QTextBrowser, QVBoxLayout
from hgoldfish.utils import eventlet
eventlet.monkey_patch()  # 开始魔术表演


class MainWindow(QWidget):
    def __init__(self, parent=None):
        QWidget.__init__(self, parent)
        self.pushButton = QPushButton("click me!", self)
        self.textEdit = QTextBrowser(self)
        self.setLayout(QVBoxLayout())
        self.layout().addWidget(self.textEdit)
        self.layout().addWidget(self.pushButton)
        self.pushButton.clicked.connect(self.sendMsg)
        self.operations = eventlet.GreenletGroup()  # 需要一个 greenet 管理器

    @eventlet.spawnInGreenlet() # 把一个函数变成协程
    def sendMsg(self, checked):
        print("sendMsg")
        # 这个函数里面可以任意写各种网络库和 time.sleep
        self.textEdit.append('1\n')
        time.sleep(2)
        self.textEdit.append('2\n')
        time.sleep(2)
        self.textEdit.append('3\n')

if __name__ == "__main__":
    import sys
    app = QApplication(sys.argv)
    windows = MainWindow()
    windows.show()
    eventlet.start_application()
