Question

Can variables in python be used to print a letter instead of a number?

Answer 1

Sure you can:

name = "Charles"
salary = 120000

print(f"{name} earns ${salary} a year.")

Answer 2

I guess you mean this:
 

x = "Hello world"

print(x)

The output would be:
Hello world
and the answer to your question is yes, by using the `String` datatype, you can store a string value in a variable, and print it out as a text.
