Finding in elements in a tuple and filtering them

Question

Assuming I have a tuple like:

[(\'text-1\',\'xxx\'), (\'img-1\',\'iii\'), (\'img-2\',\'jjj\'), (\'text-2\',\'xxx\')]

I want to filter out t

Answer 1

Just another way with generator expression (it could make some difference on large lists)

>>> l = [('text-1','xxx'), ('img-1','iii'), ('img-2','jjj'), ('text-2','xxx')]
>>> (x for x in l if x[0].find('img') == 0)
0:  at 0x917a00>
>>> gen = (x for x in l if x[0].find('img') == 0)
>>> list(gen)
1: [('img-1', 'iii'), ('img-2', 'jjj')]
