interesting gotcha

[Skaperen]

is there any reason not to do this (raw strings) for that first comment string, or any comment string, just as a matter of course everywhere including where it there is no need because there are no backslash sequences at all?

so if you need to assign a string of exactly one backslash to a variable named b, which would you use?

    b = r'\' #1
    b = '\\' #2
    b = '\\'[0] #3
