Comparing two similar Codes! One works while the other does not. Why?

This Code Works:

name = input("Please enter your name: ")

number = int(input("Please enter a number: "))

print("Hey", name + "!")

print("The number is", number, "!")

But

This Code Does Not:

name = input("Please enter your name: ")

number = int(input("Please enter a number: "))

print("Hey", name + "!")

print("The number is", number + "!")

I mainly changed the "," and the "+" and it stopped working properly.

Why????

What you are adding are different types, but before concatenation. In the first instance you are essentially formatting the integer into the string. In the second case you are trying to add (the mathematical operation) a string and an integer together, and Python doesn't know what to do in that case, so throws an error instead. Hope this helps and feel free to ask any questions.
