[SOLVED] Python how to match a character followed by anything without using regrex?

Issue

I have a bunch of string look like aaa -bx or aaa -bxx where x would be a digit. Is there any way to mach bx or bxx without using regrex? I remember there is something like b_ to match it.

Solution

You can use string methods.

Matching literal aaa -b followed by digits:

def match(s):
    start = 'aaa -b'
    return s.startswith(start) and s[len(start):].isdigit()

match('aaa -b33')
# True

If you rather want to check if the part after the last b are digits, use s.rsplit('b')[-1].isdigit()
