The f-strings, short for formatted strings, allow us to display expressions like adding a string to a number, without any error.
Every f-string statement consists of two parts, first the character f, then the string that we want to format.
Next, we add the different kind of value in curly braces so it'll display as one print statement. Like here, with {2}.
print(f"{2} new messages")
>>> print(f"{2} massages")
2 massages
