Python: get list indexes using regular expression?

Question

In Python, how do you get the position of an item in a list (using list.index) using fuzzy matching?

For example, how do I get the indexes of all fruit of the form *berry in the following list?

fruit_list = ['raspberry', 'apple', 'strawberry'] # Is it possible to do something like the following? berry_fruit_at_positions = fruit_list.index('*berry')  

Anyone have any ideas?

Answer 1

With regular expressions:

import re fruit_list = ['raspberry', 'apple', 'strawberry'] berry_idx = [i for i, item in enumerate(fruit_list) if re.search('berry$', item)] 

And without regular expressions:

fruit_list = ['raspberry', 'apple', 'strawberry'] berry_idx = [i for i, item in enumerate(fruit_list) if item.endswith('berry')] 

Answer 2

Try:

fruit_list = ['raspberry', 'apple', 'strawberry'] [ i for i, word in enumerate(fruit_list) if word.endswith('berry') ] 

returns:

[0, 2] 

Replace endswith with a different logic according to your matching needs.
