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 initialization 
List = [(', ', 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 output 
print(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 initialization 
List = [(', ', 12), ('Paras', 5), 
        ('jain.', 11), ('...', 55), 
        ('-Geek', 115), ('Geeksfor', 115), 
        (':', 63), ('Data', 3), ('-', 15), 
        ('Structure', 32), ('Algo', 80),] 
  
# Importing 
import re 
  
# Using regex 
out = [t for t in List if re.search(r'\w', t[0])] 
  
# Printing output 
print(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 initialization 
List = [(', ', 12), ('Paras', 5), 
        ('jain.', 11), ('...', 55), 
        ('-Geek', 115), ('Geeksfor', 115), 
        (':', 63), ('Data', 3), ('-', 15), 
        ('Structure', 32), ('Algo', 80),] 
  
# Using filter 
out = filter(lambda x:any(c.isalpha() 
                for c in x[0]), List) 
  
# Converting in list 
out = list(out) 
  
# Printing output 
print(out) 

Output:

[(‘Paras’, 5), (‘jain.’, 11), (‘-Geek’, 115), (‘Geeksfor’, 115), (‘Data’, 3), (‘Structure’, 32), (‘Algo’, 80)]
