The input() function in Python always returns a string, regardless of what the user types. So age holds the string "19", not the integer 19.

This is a code / query task — you are being asked to understand what the code does and what data type each variable holds after execution.

The Idea: input() Returns a String

The key concept here is that Python’s input() function reads everything from the keyboard as a string. Even if the user types digits like 19, Python treats it as the text "19" — you cannot do arithmetic on it directly.

When you write:

fname = input("Enter your first name: ")

and the user types Arnab, fname becomes the string "Arnab".

When you write:

age = input("Enter your age: ")

and the user types 19, age becomes the string "19" — not the integer 19.

Watch out

A very common mistake is to assume age is an integer and try to use it in a calculation like age + 1. That would raise a TypeError because you cannot add an integer to a string. You must explicitly convert with int(age) if you need a number.

What the Code Actually Does

After execution:

  • fname → "Arnab" (a str) …
