My python script requires an argument of type str.

I am using the ArgumentParser class from argparse.

I want to pass in a string containing a "$" char in the middle, e.g. "file$102_a.txt", but when passed to the script the argument is stored as "file" cutting off the $102_a.

Is there any way to enable argparse to do accomodate this?

Running macOS, python v3.7.6

Thank you for your help.

We can pass it with an escape sequence before the dollar sign.

Say test.py is defined as

import sys
print(sys.argv[1])

Then,

$ python test.py "dff\$sdfs"

Would print dff$sdfs

EDIT: As pointed out by user: smac89, if the arguments are enclosed within single quotes ('), instead of double quotes ("), it will not split at the dollar sign.

$ python test.py 'dff$sdfs'

Would also print dff$sdfs
