Conditional Statements

#description

Python is a high-level programming language that allows developers to create robust and sophisticated software applications. Conditional statements are used in Python to allow the execution of different blocks of code based on the evaluation of a boolean expression.

In Python, there are two types of conditional statements - if statement and if-else statement. The if statement is used to execute a block of code only if the boolean expression evaluates to True, while the if-else statement is used to execute one block of code if the expression is True, and another block of code if it is False.

Here is an example:

 
                    
num = 10
if num > 0:
    print("Number is greater than zero.")
else:
    print("Number is less than or equal to zero.")

In this example, the if statement is used to test whether the variable num is greater than zero. If num is greater than zero, the program will execute the first print statement, and if num is less than or equal to zero, it will execute the second print statement.

Conditional statements are an essential part of Python programming, as they allow developers to write programs that respond intelligently to specific input and conditions. By mastering the use of conditional statements, developers can create Python programs that are more efficient, flexible, and easy to use.
