如何双击运行带有命令行参数的python脚本

Question

As a personal project to improve my python skills I created a script that retrieves weather data. It takes multiple command line arguments to specify the location and what specific information is wanted.

I'd like to make a second file to run it with specific command line arguments using a double click. I already learned how to make it into an executable/make a second file execute it. However, I don't know how to run it with command line arguments.

Currently my secondary file (wrapper?.. unsure of terminology) looks like this:

#! /usr/bin/env python
import weather
weather.main()

This runs but I don't know how to create command line arguments for it without running from the shell. I'd like to have a simple executable to run the weather for where I am quickly.

Answer 1

Well, you can call a shell process using the os.system or the subprocess module.

os.system takes a string and passes it as a command to a shell.

import os
os.system("ls -1")

Whereas subprocess takes a list of all the arguments (the program itself being the first argument) and passes it as a command.

import subprocess

# Simple command
subprocess.call(['ls', '-1'], shell=True)

Seeing these examples, it's easy to tell that you want the executable program to call either one of these ( os.system or subprocess ). I recommend using the latter, as it offers more variety.

If you want more information, I suggest you read the review of subprocess on Python Module of the Week. .

Answer 2

Add to your wrapper script:

import sys

sys.argv[1:] = ['what', 'ever', 'u', 'want']

before the call to weather.main() .
