Usage

To use the subprocess module, you must import it into your Python script: import subprocess

Examples

Here are some common uses of the subprocess module:

Running an External Command The following runs a basic echo which prints out "Hello World" in result section:

subprocess.run(['echo', 'Hello, World!'])

Capturing Command Output

To capture the output of a command, use the capture_output=True argument:

result = subprocess.run(['ls', '-l'], capture_output=True, text=True) print(result.stdout)

Handling Errors

To handle errors in a subprocess, check the returncode:

result = subprocess.run(['false']) # 'false's if result.returncode != 0: print("Error: Command failed with status", result.returncode)
