If I can add an integer and a float, why do we have to convert the float to avoid an error?

Question

If I can say "print(1 + 2.0)" and get 3.0, then why do I get an error in the following code if I remove the second "float" conversion?

print(float(input("Enter a number: ")) + (float(input("Enter another number: "))

Answer 1

Because input() returns a string, if you don't cast the string to a float type you will be adding a float value with a string.
