Python Conditional Statements|if-elif-else statement in Python|nested-if statement in Python

In this video,we discuss about if-elif-else and nested if Statements and how to use them in Python.
In Python, conditional statements are used to make decisions in your code based on certain conditions. These statements allow you to control the flow of execution by checking whether a specific condition is true or false. The most common conditional statements in Python are the "if," "elif" (short for else if), and "else" statements.
The basic syntax for Python Conditional Statements-
if condition1:
# Code block executed if condition1 is true
elif condition2:
# Code block executed if condition1 is false and condition2 is true
else:
# Code block executed if both condition1 and condition2 are false
The "if" statement is the fundamental part of conditional statements. It checks whether a given condition is true and, if so, executes the associated code block. If the condition is false, the code block is skipped.

The "elif" statement allows you to specify additional conditions to check if the preceding "if" statement was false. You can have multiple "elif" blocks to handle different cases. When one of the "elif" conditions is met, the associated code block is executed, and the rest of the "elif" and "else" blocks are skipped.

The "else" statement provides a default option if none of the previous conditions (specified by "if" and "elif") are true. It is optional and only executes its code block when none of the previous conditions have been satisfied.

A nested if statement in Python is a way of incorporating one if statement within another if statement. This allows you to create more complex conditions and control flow in your code. The nested if statement structure looks like this:


if condition1:
# Code to be executed if condition1 is True
if condition2:
# Code to be executed if both condition1 and condition2 are True
else:
# Code to be executed if condition1 is True but condition2 is False
else:
# Code to be executed if condition1 is False
