Len, Upper and Lower

What Is Len, Upper and Lower?

.Len() is where you have a program and if you type in "print len first_name()" then if you have a variable with "first_name" then it will print how many characters are in the "first_name".

A Upper variable is where you have a program saying "print first_name.upper()" and that will make your variable or the first name what ever you named it an Upper case word or words.

A Lower variable is just the same as Upper but instead you have it saying "print first_name.lower()" and it will print it in Lower case.!
