I'm trying to convert srt to int, and I didn't know I needed to specify the base. Plus I haven't read anything that I need to specify the base for the int().

'12' is a string that contains 2 digits, which together represent the 
number 12. 'y' is a string that contains a letter, which doesn't 
represent a number.

Perhaps what you meant is that y is a variable that contains a string, 
in which case what you want is int(y).

There's no code attached; this list automatically strips attachmentments.
