What is wrong with my code? When entering a input 8 characters long without a "!", the code still accepts it

You can fix this in multiple ways.

1) Use single quotation marks instead of double, this will do the same thing.

'Enter a password with at least 8 characters and a "!" : '

What happened was "" tells the interpreter when a string begins and ends. It looks for those connecting quotation marks.

2) You can use \" to tell the interpreter that this is not the end of a string.

"Enter a password with at least 8 characters and a \"!\" : '

3) Use multiple double quotation marks (can also be used for multi-line strings).

"""Enter a password with at least 8 characters and a "!" : """
