### Cheat Sheet

#### YAML

* Read YAML
```
with open(r'/file/path') as file:
```

#### Files

* Read remote file(s)

```
from fabric import Connection

with Connection(host) as conn:
    with conn.sftp().open(path) as stream:
    ...
```

#### Dictionaries

* Define dictionary: `some_dict = {'first_number': 2017, 'second_number': 2022}`
* Add item to dictionary: `some_dict['third_number'] = 1991`
* Remove last item: `some_dict.popitem()`
* Remove item by key: `some_dict.pop("third_number")`
* Get all keys without values: `some_dict.keys()`
* Get all values without keys: `some_dict.values()`
* Access item: `some_dict['first_number']` or `some_dict.get('second_number')`
* Number of items in the dictionary: `len(some_dict)`
* Update value of a certain key: `some_dict.update({"first_number": 02017})
