Python If Statement

Python if statement

Created By: chatGPT

In Python, the if statement allows you to execute a block of code only if a specified condition is True. This is essential for controlling the flow of your program based on different conditions. Below is an example that demonstrates the basic structure of an if statement.

x = 10

if x > 5:
    print('x is greater than 5')

You can also use elif and else to handle multiple conditions. This helps in making decisions based on several conditions without nesting too many if statements.

y = 8

if y > 10:
    print('y is greater than 10')
elif y == 10:
    print('y is equal to 10')
else:
    print('y is less than 10')

It's also possible to check for multiple conditions in a single if statement using logical operators like and and or. This can make your code more concise and efficient.

z = 15

if z < 20 and z > 10:
    print('z is between 10 and 20')

if z < 20 or z == 25:
    print('z is either less than 20 or equal to 25')

You can also use if statements with lists or other data structures to check for the presence of values. Here’s how you can check if a number is in a list.

numbers = [1, 2, 3, 4, 5]

if 3 in numbers:
    print('3 is in the list')
else:
    print('3 is not in the list')

To summarize, the if statement is a fundamental concept in Python programming. It allows for decision-making based on conditions, enabling more complex and dynamic behaviors in your code.
