Run another Python script

EasyOS Module Programs · 33 of 49

Write a Python program that runs another Python script.

Output

hello from the other script
os.system returned 0
captured: hello from the other script

Approach

os.system returns the exit status; subprocess.run also captures output.

Solution

Python

import osimport subprocessimport sys with open("hello_script.py", "w") as f:    f.write("print('hello from the other script')\n") status = os.system(f'"{sys.executable}" hello_script.py')print("os.system returned", status)out = subprocess.run([sys.executable, "hello_script.py"], capture_output=True, text=True)print("captured:", out.stdout.strip())

Output

hello from the other script
os.system returned 0
captured: hello from the other script

Line by line

Line 8

os.system lets the child print directly and returns its exit status.

Line 10

subprocess.run is preferred because you can capture and check the output.
