Hi, welcome to stackoverflow. What have you tried so far? (hint: no regular expressions are needed) — msvalkon, Aug 05 '16 at 09:59

It looks like you're parsing paths, in which case you should really be using os.path instead of regex:

from os.path import basename
basename('/home//Desktop/3A5F.py')
# 3A5F.py

It is a simple split, no regex needed:

>>> "/home//Desktop/3A5F.py".split("/")[-1]
'3A5F.py'

As an alternative, you can get same result without regexps:

lines = ['/home//Desktop/3A5F.py', 'path/sth/R67G.py', 'a/b/c/d/t/6UY7.py']

result = [l.split('/')[-1] for l in lines]
print result
# ['3A5F.py', 'R67G.py', '6UY7.py']

use : [^\/]*\.py$

But this is a bad question. You need to show what you have try. Whe are not here to do your work for you.

*But this is a bad question.* - then why answer? (basically, this is a question to everyone answering here). – Wiktor Stribiżew Aug 05 '16 at 10:10

You can use this.

pattern = ".*/(.*$)"
mystring = "/home//Desktop/3A5F.py"
re.findall(pattern, mystring)

You can also use os.path.split(mystring)
