If you want to make use of Regular Expressions (RegEx) to find all matches within a Python list, you can make use of the re.findall() method.
Let's take a look at an example:
import re
def re_find_all_matches(pattern, city_list):
matches = []
for city in city_list:
result = re.findall(pattern, city)
matches.extend(result)
return matches
city_list = ["New York", "Chicago", "Ohio", "Austin", "Texas","New York","Austin"]
pattern = r"Austin"
matches = re_find_all_matches(pattern, city_list)
print(matches)
Output:
['Austin', 'Austin']
