I don’t know where is the error. HELP! (Python)

Question

I wrote this:

birth_date = 2000
age = 2020 - int(birth_date)
print ('is' + age )

And appeared this:

Traceback (most recent call last):
File "<string>", line 3, in <module>
TypeError: Can't convert 'int' object to str implicitly

I’m a beginner so maybe it’s easy but I don’t get it.
Thank you for you time.

Answer 1

Rei has given an excellent answer regarding the cause of the problem.
A Pythonic way of creating the output would be
print("Is",age)
or
print(f"Is {age}")

Answer 2

in
"is" + age
you try to append an integer into string, that's the error. to fix it convert the integer to a string first

"is" + str(age)

Answer 3

You should type print(f”Is {age}”) or print(“is” + str(age)). ‘f’ stands for formatted string.

Answer 4

ooooohh thank you so much Rei. I feel like a pro. hahaha
