So I know how to write in a file or read a file but how do I RUN another file?
for example in a file I have this: a = 1 print(a)
How do I run this using another file?

file_path = "<path_to_your_python_file>" using subprocess standard lib
import subprocess subprocess.call(["python3", file_path]) or using os standard lib
import os os.system(f"python3 {file_path}") or extract python code from the file and run it inside your script:
with open(file_path, "r+", encoding="utf-8") as another_file: python_code = another_file.read() # running the code inside the file exec(python_code) exec is a function that runs python strings exactly how python interpreter runs python files.
IN ADDITION
if you want to see the output of the python file:
import subprocess p = subprocess.Popen( ["python3", file_path], stdout=subprocess.PIPE, stderr=subprocess.PIPE ) err, output = p.communicate() print(err) print(output) EXTRA
for people who are using python2:
execfile(file_path)
