Python Basics with IF ELSE statement

Python is a high-level, interpreted programming language that is widely used for a variety of purposes, including web development, data analysis, machine learning, and automation. The IF-ELSE statement is a fundamental part of Python programming that allows developers to make decisions based on conditions.

The syntax of the IF-ELSE statement in Python is as follows:

if condition:
# code to execute if the condition is true
else:
# code to execute if the condition is false

The condition is an expression that evaluates to either True or False. If the condition is true, the code in the first block is executed, and if it is false, the code in the second block is executed.

Here is an example of using the IF-ELSE statement in Python:

# Example 1
x = 10
if x > 0:
print("x is positive")
else:
print("x is not positive")

In this example, the condition is x > 0. If x is greater than 0, the first block of code is executed, and the output will be "x is positive". If x is not greater than 0, the second block of code is executed, and the output will be "x is not positive".

You can also use multiple IF-ELSE statements to check multiple conditions. Here is an example:

# Example 2
x = 5
if x > 0:
print("x is positive")
elif x == 0:
print("x is zero")
else:
print("x is negative")

In this example, there are three conditions to check. If x is greater than 0, the first block of code is executed, and the output will be "x is positive". If x is equal to 0, the second block of code is executed, and the output will be "x is zero". If x is not greater than 0 or equal to 0, the third block of code is executed, and the output will be "x is negative".

The IF-ELSE statement is a powerful tool that allows you to make decisions in your Python code based on conditions. By using IF-ELSE statements, you can create programs that can respond to user input or perform complex calculations based on specific conditions.
