# `in` usage in python
|
||
|
||
## Definition and Usage
|
||
|
||
The `in` keyword has two purposes:
|
||
|
||
The `in` keyword is used to check if a value is present in a sequence (list, range, string etc.).
|
||
|
||
The `in` keyword is also used to iterate through a sequence in a `for` [[loop in python|loop]]:
|
||
|
||
- Loop through a list and print the items:
|
||
|
||
```python
|
||
fruits = ["apple", "banana", "cherry"]
|
||
for x in fruits:
|
||
print(x)
|
||
```
|
||
|
||
- Check if "banana" is present in the list:
|
||
|
||
```python
|
||
fruits = ["apple", "banana", "cherry"]
|
||
|
||
if "banana" in fruits:
|
||
print("yes")
|
||
```
