Python | Kth index character similar Strings

Sometimes, we require to get the words that have Kth index with the specific letter. This kind of use case is quiet common in the places of common programming projects or competitive programming. Let’s discuss certain shorthand to deal with this problem in Python.

Method #1 : Using list comprehension + lower()
This problem can be solved using the combination of above two functions, list comprehension performs the task of extending the logic to whole list and lower function checks for case insensitivity with the target word of argument letter.

# Python3 code to demonstrate 
# Kth index character similar Strings 
# using list comprehension + lower() 
  
# initializing list 
test_list = ['Akash', 'Nikhil', 'Manjeet', 'akshat'] 
  
# initializing check letter 
check = 'k'
  
# initializing K  
K = 2
  
# printing original list 
print("The original list : " + str(test_list)) 
  
# using list comprehension + lower() 
# Kth index character similar Strings 
res = [idx for idx in test_list if idx[K - 1].lower() == check.lower()] 
  
# print result 
print("The list of matching Kth letter : " + str(res)) 

Output :

The original list : ['Akash', 'Nikhil', 'Manjeet', 'akshat']
The list of matching Kth letter : ['Akash', 'akshat']
