Weird index error python

Question

I'm creating a program that iterates through a text file and, starting at the beginning of a specific set of user credentials(of which i call "Cases"), and appropriately puts the username and password characters (in hexadecimal) into appropriate username and password arrays.

although, however small, i'm getting a silly index error when iterating through the array.
have i fallen off the array at the end? someone, please tell me what i'm doing wrong.

here's the code:

This is what the notepad should look like:

0x4e
0x61
0x73
0x69
0x72
0x20
0x4d
0x75
0x68
0x61
0x6d
0x6d
0x61
0x64
UPASSWORD:
0x31
0x32
0x33
0x34
0x35
--END--

Hi,

it is quite clear that you get the index error because of this line:
while credsArr[c2Line] != "--END--" or credsArr[c2Line] != "==END==":

Think about the condition, this will be always true so the code reaches the end of your .txt file and is out of index. Try this:
while credsArr[c2Line] != "--END--" and credsArr[c2Line] != "==END==":

Let me know if this is what you were looking for.
