Python Coding Challenge - Question with Answer (ID 230926)

 

Explanaation:

🟢 Line 1: 5

5

5 is an integer (int).

So Python knows this is a numeric value.

🟡 Line 2: None

None

None is a special Python value representing no value / absence of a value.

Its type is:

type(None)

Output:

<class 'NoneType'>

🔵 Line 3: 5 + None

Python now tries to perform:

5 + None

The + operator can add compatible numeric values such as:

5 + 3

But None is not a number.

Python cannot perform:

int + NoneType

So the operation fails.

🔴 What Error Occurs?

Python raises:

TypeError

Because the two operands have incompatible types.

The actual error message is similar to:

TypeError: unsupported operand type(s) for +: 'int' and 'NoneType'

Final Ouptut:

Type Error
