How do I access command line arguments in Python

Question

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.

Answer 1

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!!

Answer 2

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']
