python if

In Python, `if` is a conditional statement that allows you to execute a block of code only if a certain condition is met. Here's the basic syntax of an `if` statement:

if condition:
    # code to execute if condition is True

The `condition` can be any expression that evaluates to a Boolean value (`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 and execution will continue with the next statement after the `if` block.

You can also use an `else` statement to specify a block of code to execute if the `condition` is `False`:

if condition:
    # code to execute if condition is True
else:
    # code to execute if condition is False

Finally, you can use an `elif` statement (short for "else if") to specify additional conditions to check:

if condition1:
    # code to execute if condition1 is True
elif condition2:
    # code to execute if condition2 is True and condition1 is False
else:
    # code to execute if both condition1 and condition2 are False

Here's an example to help illustrate how `if` statements work:

x = 5

if x > 0:
    print("x is positive")
else:
    print("x is non-positive")

In this example, the `condition` is `x > 0`. Since `x` is equal to `5`, which is greater than `0`, the code block under the `if` statement will be executed, and the output will be:

x is positive
