What is the method for installing the subprocess module in Python?

In Python, the subprocess module is a built-in module and does not require installation. You can use it directly to execute external commands, start subprocesses, and perform other operations.

Here is an example using the subprocess module:

import subprocess

# 执行外部命令
output = subprocess.run(['ls', '-l'], capture_output=True, text=True)
print(output.stdout)

# 启动子进程
subprocess.Popen(['python', 'script.py'])

Please note that the subprocess module offers a variety of functions and options. Specific usage can be found in the official documentation at: https://docs.python.org/3/library/subprocess.html
