unable to solve argument error

[Athandavamurthy]

Hello,
I am relatively new to the community!

I am using python 3.9
I am trying to learn from your code and when I run it on my cmd I get - usage: Solve.py [-h] [-q] [-c] [-C] PUZZLE [PUZZLE ...]
Solve.py: error: the following arguments are required: PUZZLE

I am passing it as you mentioned in read me file - ./pyflowsolver.py puzzles/jumbo_14x14_01.txt

Could you please guide me how issue could be resolved?
