How do i make this code recognise my input?

Question

i'm new to python and i'm trying to ask the user if they want to go again for my age calculator tool. Code:

while True:
    import datetime
    birth_year = int(input("What year were you born? "))
    current_year = datetime.datetime.now().year
    age = current_year - birth_year
    print(f"You are {age} years old now.")
    input()
    choice = input("Do you want to go again? (yes or no) ")
if "choice" == yes:
    print("enjoy")
elif "choice" == no:
    print ("Ok, quitting now")
    quit()
else:
    print("i'll assume that means yes")

First, you have to get the indentation right. In most languages, improper indentation is bad form. In Python, it's invalid syntax. — Fred Larson, Apr 07 '21 at 21:10

import datetime
while True:
    birth_year = int(input("What year were you born? "))
    current_year = datetime.datetime.now().year
    age = current_year - birth_year
    print(f"You are {age} years old now.")
    choice = input("Do you want to go again? (yes or no) ")
    if choice == 'yes':
        print("enjoy")
    elif choice == 'no':
        print ("Ok, quitting now")
        break
    else:
        print("i'll assume that means yes")

You can just take everything to infinite loop and break it whenever the user writes 'no'.

Your error is that you called the variable choice with quotes around it, making it the string "choice". Instead you should check if the variable choice contains the string 'yes' or 'no'.
To do so we can use two operators, == or the is operator.
Here is an example:

import datetime
birth_year = int(input("What year were you born? "))
current_year = datetime.datetime.now().year
age = current_year - birth_year
print(f"You are {age} years old now.")
input()
choice = input("Do you want to go again? (yes or no) ")
if choice == 'yes': # Example using the `==` operator.
    print("enjoy")
elif choice is 'no': # Example using the `is` operator.
    print ("Ok, quitting now")
    exit() # This should be `exit` not `quit`.
else:
    print("i'll assume that means yes")

Your are missing while True statement. – User123 Apr 08 '21 at 05:55 — User123, Apr 08 '21 at 05:55
