partition string in python and get value of last segment after colon

Question

I need to get the value after the last colon in this example 1234567

client:user:username:type:1234567

I don't need anything else from the string just the last id value.

Answer 1

result = mystring.rpartition(':')[2]

If you string does not have any :, the result will contain the original string.

An alternative that is supposed to be a little bit slower is:

result = mystring.split(':')[-1]
