f-Strings
In the last challenge, you output a message by passing necessary variables as string parts. Concatenation is a good approach, but wouldn't it be easier to pass variables within a string pattern, as if you’re completing a puzzle?
Python provides us with such functionality. The approach is called f-strings. To use a variable value inside the string, place the f letter to the left of the opening quotes and pass the variable's name within curly brackets {} inside the string. For example, let's output the message 'Player Alex has level 16', where Alex and 16 are stored in variables.
12345# Initial variables name = "Alex" level = 16 # Output message using f-string print(f"Player {name} has level {level}.")
As you can see, you shouldn't worry about using strings and numerical values simultaneously with this approach.
Using the same variables as in the previous chapter-challenge (name and age), output the same message as before ("name is age y.o.").
