The Spy Life help

Question

I'm dumb in Python, but why is this not working?

symbols = ["!", "@", "#", "

Answer 1

"for i in symbols:" iterates over the list values. Use "for i in range(len(symbols)):" to iterate over indexes. Check Rithea Sreng answer for more on this.

Replace doesn't change the original string. It returns a modified copy of that string:
str = str.replace( ... )

2nd case is not solved yet but it isn't hidden. You'll find the reason by yourself.

Avoid using built-in classes, functions, etc as variable names.
For example str names the string data-type built-in class.
Use a different identifier.

Answer 2

I do not know but I think it is more complex no easy so it is easier to make errors. Make easy I think is the solution
