Getting file path from command line arguments in python

Question

I would like to read a file path from command line arguments, using argparse. Is there any optimal way to check if the path is relative (file is in current directory) or the complete path is given? (Other than checking the input and adding current directory to file name if the path does not exist.)

You could use os.path.isabs.

As Display Name said, os.path.isabs along with sys.argv is probably the best:

import sys
import os

fpath = sys.argv[-1]

print(os.path.isabs(fpath))
print(fpath)

output

>>> 
True
C:\Users\310176421\Desktop\Python\print.py
>>>

some cmd stuff

C:\Users\310176421\Desktop\Python>python print.py C:\Users\310176421\Desktop\tes
t.txt
True
C:\Users\310176421\Desktop\test.txt

C:\Users\310176421\Desktop\Python>python print.py whatever
False
whatever
