What is the "if" statement in Python and how to use it?

The "if" statement in Python is used to perform conditional execution of code, i.e., to execute a certain block of code only if a specified condition is met. 

The basic syntax of the "if" statement is:

if condition:
    # code to be executed if the condition is True

The **condition** is any expression that returns a boolean value (either **True** or **False**). If the condition is **True**, the code inside the **if** block is executed. If the condition is **False**, the code inside the **if** block is skipped.

For example:

x = 10
if x > 5:
    print("x is greater than 5")

In this example, the condition **x > 5** is **True**, so the code inside the **if** block **print("x is greater than 5")** is executed, resulting in the output: **x is greater than 5**.
