In Python, nesting refers to the practice of including one statement or block of code inside another statement or block of code. This is often used to control the flow of a program, or to group related statements together.
For example, you can nest an if statement inside another if statement to create more complex conditions:
makefilex = 5
y = 10
if x < 10:
if y > 5:
print("Both conditions are true.")
In this example, the first if statement checks whether x is less than 10. If it is, then the nested if statement checks whether y is greater than 5. If both conditions are true, then the print statement is executed.
You can also nest loops inside other loops, functions inside other functions, and so on. Nesting allows you to create more complex and flexible programs by combining smaller blocks of code into larger structures. However, it's important to use indentation properly to make the code clear and easy to read.
