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})
