python if start with

In Python, the `if` statement is used to perform conditional execution. It allows you to check a condition and execute a block of code only if the condition is true. The basic syntax of the `if` statement in Python is:

if condition:
    # code to be executed if condition is true

The `condition` in the `if` statement can be any expression that evaluates to either `True` or `False`. If the condition is true, the code block indented under the `if` statement will be executed. If the condition is false, the code block will be skipped.

You can also use `elif` (short for "else if") and `else` statements to specify additional conditions to check. These statements allow you to provide alternative code blocks to execute when certain conditions are met or not met. Here's an example:

if condition1:
    # code to be executed if condition1 is true
elif condition2:
    # code to be executed if condition2 is true
else:
    # code to be executed if none of the above conditions are true

Note that the `elif` and `else` statements are optional, and you can have multiple `elif` statements if needed.
