Answer by Harley Holcombe for How do I do a case-insensitive string comparison?

Assuming ASCII strings:

string1 = 'Hello'string2 = 'hello'if string1.lower() == string2.lower():    print("The strings are the same (case insensitive)")else:    print("The strings are NOT the same (case insensitive)")

As of Python 3.3, casefold() is a better alternative:

string1 = 'Hello'string2 = 'hello'if string1.casefold() == string2.casefold():    print("The strings are the same (case insensitive)")else:    print("The strings are NOT the same (case insensitive)")
