Question

I’m new to python. I would like to trim a string only if it’s last 6 digits are zeros.
I checked the strip() methods, but I don’t see one that indicates the n number of characters to trim from right.

sample string:

20121124000000

result string should be:

20121124

Answer 1

s = s[:-6] if s.endswith('000000') else s

or define a function:

def rstrip_chars(s, chars):
    return s[:-len(chars)] if s.endswith(chars) else s

s = rstrip_chars(s, '000000')
