How to give os.system output in plainTextEdit?

Question

Python

self.plainTextEdit.setPlainText(os.system("my.exe "+self.lineEdit.text()))

Tried in different ways, but always throws with an error:

Traceback (most recent call last):
File "d:\python\gui\outputpyfile.py", line 77, in buttonClicked1
self.plainTextEdit.paste(os.system("my.exe "+self.lineEdit.text() ))
TypeError: paste(self): too many arguments

Answer 1

Solution :

stream = os.popen("my.exe "+self.lineEdit.text())
        self.plainTextEdit.setPlainText(stream.read())
