Python 3 offers a nice alternative to string concatenation. To use an f string, just place an f before a string literal:
f"your text here"
Then you can insert any variables or expressions into your string without the + sign or converting them into strings by enclosing them in curly brackets, {}.
f"your {variable} here"
Look at this code:
first_name = "Minnie"
last_name = "Mouse"
age = 30
print(first_name + " " + last_name + " is " + str(age) + " years old.")
Here is the last line rewritten using an f string:
print(f"{first_name} {last_name} is {age} years old.")
Notice that age was automatically converted to a string! Using f-strings can improve readability over string concatenation.
