当cmd是文本变量时运行subprocess.call（cmd）
[英]Run subprocess.call(cmd) while the cmd is a text variable
问题描述
In python, is it possible to run a shell command, while the command stored in variable as text ? 
在python中，是否可以运行shell命令，而该命令以文本形式存储在变量中？ for example: 例如：
self.command_editor = QTextEditor()
self.command_editor.append("echo command")
cmd = str(self.command_editor.toPlainText())
call(cmd)
this code doesn`t work! 此代码不起作用！

this is the right answer: 这是正确的答案：
self.command_editor = QTextEditor()
self.command_editor.append("echo command")
cmd = str(self.command_editor.toPlainText())
call(cmd, shell = True) #the mistake was here
