Given a List of Strings, perform removal of all Strings with non-english characters.
Input : test_list = [‘Good| ????’, ‘??Geeks???’]
Output : []
Explanation : Both contain non-English charactersInput : test_list = [“Gfg”, “Best”]
Output : [“Gfg”, “Best”]
Explanation : Both are valid English words.
Method #1 : Using regex + findall() + list comprehension
In this, we create a regex of unicodes and check for occurrence in String List, extract each String without unicode using findall().
Python3
# Python3 code to demonstrate working of # Remove Non-English characters Strings from List # Using regex + findall() + list comprehension import re # initializing list test_list = ['Gfg', 'Good| ????', "for", '??Geeks???'] # printing original list print("The original list is : " + str(test_list)) # using findall() to neglect unicode of Non-English alphabets res = [idx for idx in test_list if not re.findall("[^\u0000-\u05C0\u2100-\u214F]+", idx)] # printing result print("The extracted list : " + str(res)) |
Method #2 : Using regex + search() + filter() + lambda
In this, we search for only English alphabets in String, and extract only those that have those. We use filter() + lambda to perform the task of passing filter functionality and iteration.
Python3
# Python3 code to demonstrate working of # Remove Non-English characters Strings from List # Using regex + search() + filter() + lambda import re # initializing list test_list = ['Gfg', 'Good| ????', "for", '??Geeks???'] # printing original list print("The original list is : " + str(test_list)) # using search() to get only those strings with alphabets res = list(filter(lambda ele: re.search("[a-zA-Z\s]+", ele) is not None, test_list)) # printing result print("The extracted list : " + str(res)) |
