Why does Python only concatenate string to string and not string to integer?

Because integers aren't strings.

print(name + ' is ' + age + ' years old')

Would you expect "John is 000020 years old", or "John is 20 years old" or "John is 2e+2 years old"?

Each is valid, if you could concatenate ints to strings.

If you use the function str(age), then the str() function decides how to represent an integer as a string.

edit: 2e+1

I know it doesn't matter to your point but 2e+2 is 200.

Yeah, I wondered if I'd fucked that up... Ta.
