python find matches from a list

I am new to python, i am trying to search ad get all matched items from a list in python, however i am not getting if my input is case sensitive compared with List items.

The code which i am trying is below

# dl is available items in the list
dl=['AA_Food', 'FOOD_ORDER', 'AA_FOOD_APP', 'HOTPATH', 'FO_HOT', 'TEST_FOOD']
# search items 
r = re.compile(".*FOO.*")
newlist = list(filter(r.match, dl)) # Read Note
nl = json.dumps(newlist)
print(nl)

I am getting the below result:

["FOOD_ORDER", "AA_FOOD_APP", "TEST_FOOD"]

But the expected result is:

["AA_Food", "FOOD_ORDER", "AA_FOOD_APP", "TEST_FOOD"]

please help.

It may be because in the expression you have strictly defined FOO to be uppercase. Try using (FOO|Foo) in place of FOO.

Hopefully, it works for you.

I dont see why you need to use regular expressions. This can be done simply by using list comprehension

new_list = [item for item in dl if "foo" in item.lower()]

Use re.IGNORECASE for this

import re

# dl is available items in the list
dl=['AA_Food', 'FOOD_ORDER', 'AA_FOOD_APP', 'HOTPATH', 'FO_HOT', 'TEST_FOOD']
# search items 
r = re.compile(".*FOO.*", re.IGNORECASE)
newlist = list(filter(r.match, dl)) # Read Note
print(newlist)
