Python Coding challenge - Day 1239| What is the output of the following Python Code?

 

Code Explanation: 

Line 1: Import the inspect Module

import inspect

Explanation

Imports Python's built-in inspect module.

The inspect module is used to examine or inspect Python objects such as:

Functions

Classes

Modules

Methods

Variables

Signatures

Some useful functions include:

inspect.isfunction()

inspect.ismethod()

inspect.isclass()

inspect.getsource()

inspect.signature()

Line 2: Define a Function

def hello():

Explanation

Defines a function named hello.

A function is a reusable block of code.

At this point, the function is created but not executed.

Current state:

Function Name: hello

Status: Defined

Line 3: pass Statement

pass

Explanation

pass is a placeholder statement.

It tells Python that the function has no implementation yet.

It prevents an IndentationError when the function body is empty.

This function is equivalent to:

def hello():

    # Nothing happens here

Line 4: Check Whether hello Is a Function

print(inspect.isfunction(hello))

Explanation

inspect.isfunction() checks whether the given object is a user-defined function.

Here, hello is passed as an object (without parentheses).

Python checks:

Is hello a function?

Answer:

Yes

So it returns:

True

Output

True
