Write a Python program to execute a shell command and store its output in a variable. Write a Python program to run a system command in the background and capture its output later. Python Code Editor: Next:
Execute the stringcmdin a shell withos.popen()and return a 2-tuple(status,output).cmdis actually run as{cmd;}2>&1, so that the returned output will contain output or error messages. A trailing newline is stripped from the output. The exit status for the command can be interpreted acco...
os.system(command) Execute the command (a string) in a subshell. This is implemented by calling the Standard C function system(), and has the same limitations. Changes to sys.stdin, etc. are not reflected in the environment of the executed command. If command generates any output, it will...

我们将['ls', '-al']列表传递给subprocess.run()1 。这个列表包含命令名ls,后面是它的参数,作为单独的字符串。注意,通过['ls –al']是不行的。我们将命令的输出作为字符串存储在outputStr2 中。subprocess.run()和locale.getdefaultlocale()的在线文档会让你更好地了解这些函数是如何工作的,但是它们让代码可...

>>> subprocess.check_output('exit 1', shell=True) Traceback (most recent call last): …… subprocess.CalledProcessError: Command 'exit 1' returned non-zero exit status 1 >>> 默认的,该函数会返回编码的字节。实际输出的编码可能依赖被调用的命令。 所以,对于输出text的解码经常需要在应用层处理。
选择Python解释器。打开Python文件,VSCode会自动显示系统中配置的Python解释器,显示在左下角。如需切换解释器,点击左下角选择,选择所需的版本。运行Python程序。有两种方法运行Python文件:右键选择“Run Python File in Terminal”,或在工作区的“test.py”文件上点击右键选择相同选项。调试Python程序。Pyt ...
