I am new at python and i'm trying to teach myself the best way i can. So i will make noob mistakes. I was wondering if you could tell me where my code is going wrong and how i could improve it?

I have been trying to make a simple age calculator as part of the questions i have recieved at school.

The question is:

Write a program that asks the user to enter their age (in years).

- If the user is 100 or older, tell them You've already turned 100!.
- If they are less than 0, tell them Try again after you are born!.
- If neither of these cases apply, calculate the number of years before they turn 100 and output the message You will be 100 in x years! (where x is - replaced by the number of years before they turn 100).
- You must use an if...elif...else statement for this problem.

my code

age = int(input("Enter your current age in years: "))

if (age >= 100):
   print("You've already turned 100!.") 

elif:
     for age in range( 0 > -100:)
     print("Try again after you are born!.")

else:
     x = (int(age - 100 ))
     print("You will be 100 in" x "years!" )
