# How to Check if a List Contains a Specific Element

You can use the `in` operator to determine if a specific element exists in a list.

To check if an element does not exist in a list, use the `not in` operator.

<br />

## in Operator

The `in` operator checks if a specific element is included in a list.

The `in` operator returns `True` if the element is in the list, and `False` if it is not.

```python title="Example of in Operator"
fruits = ["apple", "banana", "cherry"]

print("apple" in fruits)  # True

print("orange" in fruits)  # False
```

<br />

## not in Operator

The `not in` operator checks if a specific element is not included in a list.

It returns `True` if the element is not in the list, and `False` if it is.

```python title="Example of not in Operator"
fruits = ["apple", "banana", "cherry"]

print("orange" not in fruits)  # True

print("apple" not in fruits)  # False
```

Check if 'orange' is included in the list 'fruits' and print 'False'. This explains how to use the 'in' operator to check for the existence of a specific element in a list.
