Strings are anything between "" or ''. It makes no difference if you use single quotes or double quotes. For example,
myFirstString = 'I am a string!' #single quotes
mySecondString = "Me too!" #double quotes
There are many things you can do with strings, using methods.
.length will give you the number of characters in a string.
"Hi!".length #is 3
.reverse will flip the string around.
"Hi!".reverse #is !iH
.upcase will make a string all caps.
"Hi!".upcase #is HI!
and .downcase will make a string all lowercase.
"Hi!".downcase #is hi!
There are many more methods, but I am not going to list them all.
You can also use many methods at once. They are solved from left to right.
"Hi!".downcase.reverse #is !ih
Take the given string and use methods to make the code print out "!edoc ma i !ih".
