hi, just look for help with case insensitivity. im working with 2 list and using a for loop to cycle through one to check if usernames are in another. thank you all

!d str.lower

str.lower

str.lower()```
Return a copy of the string with all the cased characters [[4]](https://docs.python.org/3/library/stdtypes.html#id15) converted to lowercase.

The lowercasing algorithm used is [described in section 3.13 ‘Default Case Folding’ of the Unicode Standard](https://www.unicode.org/versions/Unicode16.0.0/core-spec/chapter-3/#G33992).

[lavish brook]

you need to compare lower string to lower string

also you can't compare list == str

that will never be true

that's what you are doing in current_users == users.lower()

it may help if you name your variables with proper plurality

for user in new_users: ...

the iteration variable only represents one user at a given moment

[inner dirge]

so i need to compare the strings from the lists rather than the lists themselves? sorry is just confusing

[vital ridge]

yes, because they are different types

For example,
try comparing a class of students vs just a student, that's not a fair comparison

[spice nova]

You need to keep in mind what you're looking at. A single string eg "Rogers" you can compare it with another string, or see if it in "in" a list of strings.
But because both lists have various cases upper/lower what you would normally do is convert both strings to the same form such as all lowercase, then compare the strings.
Because "Fred" != "freD" but "fred" == "fred"

[inner dirge]

this has appeared to work although not sure if its still case sensitive

[lavish brook]

it's still case sensitive because you are comparing it against cased strings in current_users

[inner dirge]

i also changed the currents_users to lowercase

[lavish brook]

that would work then

[inner dirge]

thank you. my outputs were lowercase too. but i changed the

removed*, user =users.lower() and placed user.lower after the if and elif statement

[spice nova]

Like if user.lower() in current_users ? That's fine. But note that this: user = user.lower() is also fine in that it doesn't change the content of the new_users list. It just makes a new string in lowercase and points user at that new string. Previously it was pointing at the string from new_users.

Also, you don't need the elif ... not in test - if you get there, you already know it's not in because the in test above failed. So you can just use else.
