如何将 python CLI 程序的终端 output 重定向到 PyQt5 GUI 应用程序内的不可编辑的“QTextEdit”？

Question

I am new to PyQt5 .我是PyQt5的新手。 I have a CLI app written in python (" ping.py "), that prints ping result into the terminal.我有一个用 python（“ ping.py ”）编写的 CLI 应用程序，它将 ping 结果打印到终端。 I want to call it from another PyQt5 GUI app (" test.py "), so that the terminal output of ping.py is printed not to terminal, but inside non-editable QTextEdit of the PyQt5 GUI (" test.py "), in parallel and in real-time (redirection) , just as it would on the terminal.我想从另一个 PyQt5 GUI 应用程序（“ test.py ”）调用它，以便 ping.py 的终端output不打印到终端，而是在 Z8BDB75FF7B8CpyD600ACD789FEE.3 的不可编辑QTextEdit中打印。，并行和实时（重定向） ，就像在终端上一样。 Any help is much appreciated.任何帮助深表感谢。 Relevant codes are given below.相关代码如下。

ping.py :平.py ：

import os

response = os.popen("ping www.google.com")

for j in response:
    print(j)

test.py :测试.py ：

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_MainWindow(object):
    def setupUi(self, MainWindow):
        MainWindow.setObjectName("MainWindow")
        MainWindow.resize(285, 445)
        self.centralwidget = QtWidgets.QWidget(MainWindow)
        self.centralwidget.setObjectName("centralwidget")
        self.textEdit = QtWidgets.QTextEdit(self.centralwidget)
        self.textEdit.setGeometry(QtCore.QRect(10, 10, 261, 391))
        self.textEdit.setReadOnly(True)
        self.textEdit.setObjectName("textEdit")
        MainWindow.setCentralWidget(self.centralwidget)
        self.menubar = QtWidgets.QMenuBar(MainWindow)
        self.menubar.setGeometry(QtCore.QRect(0, 0, 285, 21))
        self.menubar.setObjectName("menubar")
        MainWindow.setMenuBar(self.menubar)

        self.retranslateUi(MainWindow)
        QtCore.QMetaObject.connectSlotsByName(MainWindow)

    def retranslateUi(self, MainWindow):
        _translate = QtCore.QCoreApplication.translate
        MainWindow.setWindowTitle(_translate("MainWindow", "MainWindow"))
        self.textEdit.setHtml(_translate("MainWindow", "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 4.0//EN\" \"http://www.w3.org/TR/REC-html40/strict.dtd\">\n"
"<html><head><meta name=\"qrichtext\" content=\"1\" /><style type=\"text/css\">\n"

"<p style=\" margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px;\">Hello</p></body></html>"))


if __name__ == "__main__":
    import sys
    app = QtWidgets.QApplication(sys.argv)
    MainWindow = QtWidgets.QMainWindow()
    ui = Ui_MainWindow()
    ui.setupUi(MainWindow)
    MainWindow.show()
    sys.exit(app.exec_())

You could change ping.py to have a function that returns the results of the ping:您可以将ping.py更改为具有返回 ping 结果的 function：

import os


def test_connection():
    response = os.popen("ping www.google.com")

    k = []
    for j in response:
        k.append(j)
    return k

And then you can import ping.py into the test.py module and call it like this:然后您可以将ping.py导入test.py模块并像这样调用它：

import ping

x = ping.test_connection()
print(x)

The result would be this:结果将是这样的：

['\n', 'Pinging www.google.com [2a00:1450:4009:817::2004] with 32 bytes of data:\n', 'Reply from 2a00:1450:4009:817::2004: time=25ms \n', 'Reply from 2a00:1450:4009:817::2004: time=10ms \n', 'Reply from 2a00:1450:4009:817::2004: time=10ms \n', 'Reply from 2a00:1450:4009:817::2004: time=12ms \n', '\n', 'Ping statistics for 2a00:1450:4009:817::2004:\n', '    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),\n', 'Approximate round trip times in milli-seconds:\n', '    Minimum = 10ms, Maximum = 25ms, Average = 14ms\n']

Note the result is an array because i set that, but you could return whatever you wanted...注意结果是一个数组，因为我设置了它，但你可以返回任何你想要的......
