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']
