Sometimes, we require to get the words that end 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 shorthands 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 # Words with Particular Rear letter # using list comprehension + lower() # initializing list test_list = ['Akash', 'Nikhil', 'Manjeet', 'akshat'] # initializing check letter check = 'T' # printing original list print("The original list : " + str(test_list)) # using list comprehension + lower() # Words with Particular Rear letter res = [idx for idx in test_list if idx[len(idx) - 1].lower() == check.lower()] # print result print("The list of matching last letter : " + str(res)) |
The original list : ['Akash', 'Nikhil', 'Manjeet', 'akshat'] The list of matching last letter : ['Manjeet', 'akshat']
Method #2 : Using list comprehension + endswith() + lower()
This method is similar to the above method but rather than checking for equality with operator, it checks using the endswith function which is inbuilt provided by python inbuilt library.
# Python3 code to demonstrate # Words with Particular Rear letter # using list comprehension + endswith() + lower() # initializing list test_list = ['Akash', 'Nikhil', 'Manjeet', 'akshat'] # initializing check letter check = 'T' # printing original list print("The original list : " + str(test_list)) # using list comprehension + endswith() + lower() # Words with Particular Rear letter res = [idx for idx in test_list if idx.lower().endswith(check.lower())] # print result print("The list of matching last letter : " + str(res)) |
The original list : ['Akash', 'Nikhil', 'Manjeet', 'akshat'] The list of matching last letter : ['Manjeet', 'akshat']
