python raw string help

[mg24]

Hi Team,

Can we use r as raw string for variable folder_path.
because user is passing folderpath via command line.



Path(r'E:\data\transport_data') I understood this line of code.

Path(r{source_path}) .......... can we use r word infront of source_path

from pathlib import Path

#1)  r string in path  , I understood this approach.
source_path = Path(r'E:\data\transport_data')  # hard code path
source_path = Path(r{source_path}) 

print(source_path)

All str objects are raw. Only string literals are not raw. A string command line argument is raw.

import sys
print("Literal")
print("C:\\name\things\really\badly.txt")
print("\nCommand Line")
print(sys.argv[1])

Output:
>>> python test.py "C:\\name\things\really\badly.txt"
Literal
ealladly.txts

Command Line
C:\\name\things\really\badly.txt

No escape sequence substitution because the command line argument is not a Python str literal.

Can you demonstrate why you think you need this: Path(r{source_path})
