Python | Remove tuple from list of tuples if not containing any character
Given a list of tuples, the task is to remove all those tuples which do not contain any character value.
Example:
Input: [(', ', 12), ('...', 55),
('-Geek', 115), ('Geeksfor', 115),]
Output: [('-Geek', 115), ('Geeksfor', 115)]
Method #1 : Using list comprehension
# Python code to remove all those # elements from list of tuple# which does not contains any alphabet. # List initializationList = [(', ', 12), ('Paras', 5), ('jain.', 11), ('...', 55), ('-Geek', 115), ('Geeksfor', 115), (':', 63), ('Data', 3), ('-', 15), ('Structure', 32), ('Algo', 80),] # Using list comprehension out = [(a, b) for a, b in List if any(c.isalpha() for c in a)] # Printing outputprint(out) |
Output:
[(‘Paras’, 5), (‘jain.’, 11), (‘-Geek’, 115), (‘Geeksfor’, 115), (‘Data’, 3), (‘Structure’, 32), (‘Algo’, 80)]
Method #2 : Using Regex
# Python code to remove all those # elements from list of tuple# which does not contains any alphabet. # List initializationList = [(', ', 12), ('Paras', 5), ('jain.', 11), ('...', 55), ('-Geek', 115), ('Geeksfor', 115), (':', 63), ('Data', 3), ('-', 15), ('Structure', 32), ('Algo', 80),] # Importingimport re # Using regexout = [t for t in List if re.search(r'\w', t[0])] # Printing outputprint(out) |
Output:
[(‘Paras’, 5), (‘jain.’, 11), (‘-Geek’, 115), (‘Geeksfor’, 115), (‘Data’, 3), (‘Structure’, 32), (‘Algo’, 80)]
Method 3 : Using Filter and lambda
# Python code to remove all those # elements from list of tuple# which does not contains any alphabet. # List initializationList = [(', ', 12), ('Paras', 5), ('jain.', 11), ('...', 55), ('-Geek', 115), ('Geeksfor', 115), (':', 63), ('Data', 3), ('-', 15), ('Structure', 32), ('Algo', 80),] # Using filterout = filter(lambda x:any(c.isalpha() for c in x[0]), List) # Converting in listout = list(out) # Printing outputprint(out) |
Output:
[(‘Paras’, 5), (‘jain.’, 11), (‘-Geek’, 115), (‘Geeksfor’, 115), (‘Data’, 3), (‘Structure’, 32), (‘Algo’, 80)]
