然后,在Python代码中,我们可以使用subprocess.run来执行这个脚本,并通过env参数传递环境变量: import osimport subprocess# 加载环境变量from dotenv import load_dotenvload_dotenv()# 获取脚本的路径script_path = os.environ.get('SCRIPT_PATH', 'default/path/to/script.sh')# 使用subprocess.run执行脚本result =...

Python 的subprocess.run()函数可以在subprocess模块中找到,它可以在 Python 程序中运行 Shell 命令,然后将命令输出显示为字符串。例如,下面的代码运行ls –al命令: >>>importsubprocess, locale>>>procObj = subprocess.run(['ls','-al'], stdout=subprocess.PIPE)# 1>>>outputStr = procObj.stdout.decode(l...
Check names and values of environment variables for accuracy. Use os.getenv() function to retrieve values and verify correct settings. Scope of environment variables: Ensure proper propagation to relevant subprocesses. Pass variables as arguments or use tools like subprocess or os.environ. ...
