Welcome back to the forum @imanwashere

find is again returning -1 for uppercase letters, and for the space character, too. You are going to take care of the space later on.

For now, instead of iterating over text, change the for loop to iterate over text.lower().

Here is the orginal for loop.

for char in text:

This is the output.

A result of -1 means a match was not found.

Adding the .lower() method to the text variable converts all the letters to lower case.

For this step, the shift variable is not used.

Happy coding

The shift variable will be used at a later point. For now, it has been declared but isn’t actually serving any useful purpose. This will all be explained as you progress through the following steps.
