[issue31253] Python fails to parse commented out code

[Andrew Wall]

Andrew Wall added the comment:

My lazy way of programming is to piece together lines of code, going round and 
round commenting and uncommenting sections until I get something that works.

My new lazy way of commenting out larger chunks of code will be:

r'''
... several lines of code here ...
'''

[issue31253] Python fails to parse commented out code

[Vedran Čačić]

Vedran Čačić added the comment:

That's because it is not commented code, it is a multiline string literal. And 
it is not raw, so \Un... is just an error, since n is not a valid hexadecimal 
digit. In the first code, \Un... is inside a raw string so it is read literally.

There is nothing to fix here. If you really want to continue confusing string 
literals and comments, you'll have to use r'''...''' to be a bit more general 
for this case.

New submission from Andrew Wall:

Python can parse and run this code:

log = list(r'..\Unknown\*.txt')


but not this:

'''
log = list(r'..\Unknown\*.txt')
'''
