Help with converting a String to a integer. PYTHON

[nateplayz50]

This is for my brothers birthday and here is my code so far 

name = input("enter Name ")
input("Is " + name + " correct? ")
month = input("enter month that you were born in ")
input("Is " + month + " correct? ")
day = input("enter day that you were born in ")
input("Is " + day + " correct? ")
year = input("enter year that you were born in ")
input("Is " + year + " correct?")
age = 2023 - year
print("seems like It is" + name + age + "BIRTHDAY!!!!!!!!!!!" )

what error are you getting. cant you not just leave it in python?

[nateplayz50]

it says "unsupported operand type(s) for -: 'int' and 'str'"

[CyberneticTitan]

The problematic line is this:

 

age = 2023 - year

and I think the error message would have given you the line number where the error occured.

 

In this case, input() returns a string, and you are trying to subtract a string (year) from a integer literal (2023).

 

One way to alleviate this is to cast year into an integer and then cast age into a string.

 

age = 2023 - int(year)
print("seems like It is" + name + str(age) + "BIRTHDAY!!!!!!!!!!!" )

do you know datatypes ? I think you need to learn that first

python has built in data types for manipulating data

 

integers (int): whole numbers without a decimal point

floating points (float): numbers with a decimal point

strings (str): this is what the built in input() returns (even if the user inputs a number). are written inside single or double quotes

boolean (bool): True or False, used for control statements

 

and tuples, sets, dictionaries

 

You can learn more about these data types from:
