Make if statment not care about capitalisation

Question

I want to make if comparisons not care about the capitals.

I have tried to Google this but nothing shows up with the answer im looking for.

Example Code:

word = input()
if word == 'banana':
    print("Apples")

Answer 1

Can do:

word = input()
if word.lower() == 'banana':
    print("Apples")

Also recommend: How do I do a case-insensitive string comparison?

Answer 2

Use the built-in lower() function like this:

word = input()
if word.lower() == 'banana':
    print("Apples")

Answer 3

You could transform input to lowercase like this:

word = input()
if word.lower() == 'banana':
    print("Apples")
