Running in shell renamethemsubs.py, 2nd part fails at string ?

[scriber10]

Hello,
Thank you for creating this python script.

I am using this on an Ubuntu shell session "renamethemsubs.py" it asks for extension of subtitle and I input srt or .srt and gives errors afterwards.

Should I use another string or way to fix this?

`$ python renamethemsubs.py
MENU

--------------------
For subs and video files,
1. In same directory
2. In different directory
3. In current directory: /home/Test
--------------------

Enter choice(1-3): 3

Extension of subtitle files(ex: .sub, .srt, etc): .srt
Traceback (most recent call last):
File "renamethemsubs.py", line 94, in
main()

for_current_dir()
File "renamethemsubs.py", line 60, in for_current_dir
sub_format = str(input("Extension of subtitle files(ex: .sub, .srt, etc): "))
File "", line 1
.srt
