Python get file relative to command line user

I'm writing a python script that will be aliased and run from various directories like this:

# working
python myScript.py file.txt

or:

# not working
python script/myScript.py other_file.txt

I'm referencing the file input like this:

file = sys.argv[1]

How can I have the script look for the file based on the command line users location instead of relative to the script's location?

Try this:

import os

print(os.getcwd())

This will give you the current working directory(cwd). And using other functions like os.path.join, you can achieve what you want.

Full example:

import os
import sys

def main():
    if len(sys.argv) < 2:
        print('Not enough arguments.')
        sys.exit(1)

    print('Current working directory: %s' % os.getcwd())
    print('What you want: %s' % os.path.join(os.getcwd(), sys.argv[1]))

if __name__ == '__main__':
    main()

Try using it.
