using f string and .format together

Question

name = input("Please enter your name: ")
age= int(input("How old are you,{0}?" .format(name)))

print(age)

if age >= 22:
    print(f"Congratulations {name} , You're eligible to vote.")
else:
    print(f"Oops {name} ,We're are sorry but you can try again in {0} years." .format(22 - age))

The outcome is not minusing the .format command? can we not use both the functions into one line of code.

The f string is evaluated to a str which has the format method, so yes, it will work. The trick is that you have to escape the brackets intended for the format method so that they resolve properly later.

>>> foo = "bar"
>>> f"foo {foo} 0 {{0}}".format("baz")
'foo bar 0 baz'

Notice that {{0}} resolves to {0} in the f string and then to the first formatted parameter.

This makes no sense at all, you can do everything with f-strings:

name = input("Please enter your name: ")
age = int(input(f"How old are you {name}? "))
print(age)
if age >= 22:
    print(f"Congratulations {name}, You're eligible to vote.")
else:
    print(f"Oops {name}, We're are sorry but you can try again in {22 - age} years.")

f-strings are now the best option. For more info see: https://peps.python.org/pep-0498/#abstract

While you're not wrong, per se, this does not actually answer the question and belongs in a comment instead.
