使用包装器脚本中的参数调用python脚本

Question

What I am trying to do is create a wrapper script, let's say program1.py , that calls program2.py and program3.py from main() . program1.py , program2.py , and program3.py all need to have their own arguments. What is the best way to go about creating this wrapper script? Should I prompt the user before running the program2.py script from program1.py 's main method?

Answer 1

when passing arguments to Subprocess you need to pass it a list containing each word in the command you want to execute eg

subprocess.Popen(['python', 'program2.py', argv[1], argv[2]])

would execute program 2 with the arguments argv[1] and argv[2] of the wrapper process.

If argv[1] = 'hello' and argv[2] = 'world'

python program2.py hello world

would be executed.
