RE: List logic - Low_Ki_ - Apr-23-2017

so here is another one... how do I get the \ in invalidChars list without it showing up as double \\

def getUserInfo():

    while True:
        print('Enter a valid username: ')
        username = input()
        invalidChars = '!@#$%^&*()+=~`{}|[]:;"<,.>/ ?\\'
        invalidList = []
        for l in invalidChars:
            invalidList.append(l)

        print(invalidList)
        break
getUserInfo()
Output:
Enter a valid username: 
f
['!', '@', '#', '$', '%', '^', '&', '*', '(', ')', '+', '=', '~', '`', '{', '}', '|', '[', ']', ':', ';', '"', '<', ',', '.', '>', '/', ' ', '?', '\\']

for chars in list(zip(*grid[::-1])):
    print(''.join(chars))
Output:
..OO.OO..
.OOOOOOO.
.OOOOOOO.
..OOOOO..
...OOO...
....O....
I was lazy and found how to rotate the matrix on SO. :-)

NIIIIOCCCCEEEE dudeeee :D haha thanks :P
I've played with this until my brain aches... i know im missing something simple... can someone please help. I'm just trying to compare the username to characters in the invalidList to make sure no illegal characters are allowed in a username:

def getUserInfo():

    while True:
        print('Enter a valid username: ')
        username = input().lower()
        invalidChars = '!@#$%^&*()+=~`{}|[]:;"<,.>/ ?\\'
        invalidList = []
        for l in invalidChars:
            invalidList.append(l)

        for x in username.split():
            for j in x:
                if j in invalidList:
                    print('oops')
                else:
                    break
        if any([x in invalidList for x in list(username)]):
            print('oops')
        else:
            break
Am i close? lol...
Ahhh... There it is:

        for x in list(username):
            if x in invalidList:
                print('oops')
