How to use if and else in python

In Python, the `if` statement is used to execute a block of code if a certain condition is true, while the `else` statement is used to execute a block of code if the `if` condition is not true.

The basic syntax is as follows:

if condition:

# code to be executed if the condition is true

else:

# code to be executed if the condition is false

```

Here's an example to illustrate the usage:

```python

x = 10

if x > 5:

print("x is greater than 5")

else:

print("x is less than or equal to 5")

In this example, if the condition `x > 5` is true, the first print statement will be executed, otherwise the second print statement will be executed.
