write better code instead of 2 for loops

Question

I have 2 for loops and I want to make it better like list comprehension or lambda or else. how can i achieve the same?

for example :

filename = ['a.txt', 'b.txt', 'c.txt']
for files in filename:
    for f in glob.glob(os.path.join(source_path, files)):
        print f
        ... some processing...

Your code is perfectly fine as it is. You can only make it less legible by introducing unnecessary complex constructs.
