I'm not sure how you're running your program, but that's not valid, and you should be getting errors.

Let's talk style! Instead of...

print("");print("");print("This program will return all the letter conbinations")
print(                          "that are available on the modern phone")
print("You just type in a seven digit number and let the program display")
print("all the letter conbinations that make up that number  Enjoy");print("")

...try this!

docs = """This program will return all the letter conbinations
that are available on the modern phone
You just type in a seven digit number and let the program display
all the letter conbinations that make up that number  Enjoy"""

print(docs)
