Removing Case Sensitivity in Python?

[Red Saum]

How can I remove case sensitivity for the purpose of this little exercise?

 

names = ['Ashton', 'Paris', 'Britton', 'QUIT', 'Aaron']
for name in names:
	if name == 'QUIT':
    	break
    print(name)

I'm trying to make it so I can say name == 'quit' or something without having to worry about the case. Not really useful or necessary, just curious about it.

string = string.upper() will make it uppercase.

Well I know that, but what if I just want to make the case not matter entirely? Like I said, it's not really necessary, I'm just curious about it...

if(string1.upper() == string2.upper()):

 

It doesn't change the string, it just compares an uppercase version of the string. It's making the case not matter.

Okay. Is there not a way to make the whole "concept" of cases disappear from the program, rather than make it just "not matter"? Maybe I'm just playing around something that doesn't exist...

Concept of cases is actually locked in to the actual string comparison
No real easy way to redefine it.

But as @Red Saum & @djdwosk97 suggested, just uppercase both strings in the comparison. It will be case insensitive

This IS the way to make "case" disappear...

You make them both the same case, either upper or lower and compare them.

That's literally what allows you to compare things with different cases while disregarding the case.

.upper, .lower, .casefold, you can use any of these to get what you want.

This is how programming works.

 

If you magically make case disappear then how would other people use the program if they wanted to have case sensitive stuff...

It's simply not possible to make case disappear, all keyboards and computers have upper and lower case. That's what ASCII is, unless you want to invent your own character code that has no case.

You could overload the equality operator within a class so that you could just do if(string1 == string2), but in the overload you'd have to do something like string.uppercase().

If going the .upper() or .lower() route, you should use .casefold() instead. It converts to lowercase but works better for certain unicode characters.
