How do I access command line arguments in Python

0 votes

I use python to create my project settings setup, but I need help getting the command line arguments.

I tried this on the terminal:

$python myfile.py var1 var2 var3

In my Python file, I want to use all variables that are input.

Hii,

You can use sys.argv to get the arguments as a list.

If you need to access individual elements you can use:

sys.argv[i]  

where i is the index 0 that will give you the python filename being executed. Any index after that are the arguments passed.

Thank You!!

import sys
print(sys.argv)

More specifically, if you run python example.py one two three:

>>> import sys
>>> print(sys.argv)
['example.py', 'one', 'two', 'three']
