pyyaml

Below will be None in python

  • null/Null/NULL/~ or key: <- empty

Below will be boolean, If need string, should use "True" rather than True

  • true/True/TRUE/yes/Yes/YES/on/On/ON
  • false/False/FALSE/no/No/NO/off/Off/OFF

Below distinguish dict and string

  • key: value in which : followed by space will be dict
  • key:value like https: will be string

https://example.com/ 中的冒号 : 后面有斜杠 //，YAML 解析器会将整个值识别为字符串

Regex

matches = re.finditer(r"### \d+\. `(.*?)` - (.*?)\n\n```\w+\n(.*?)```", raw, re.MULTILINE | re.DOTALL)
for match in matches:
    file, statment, content = match.group(1), match.group(2), match.group(3)
    os.makedirs(os.path.dirname(file), exist_ok=True)
    with open(file, "w", encoding="utf8") as f:
        f.write(content)

Networkx

import networkx as nx

G = nx.Graph()
G.add_edges_from([(1, 2), (2, 3), (3, 4), (4, 1)])

subgraph = nx.subgraph(G, [1, 2, 3])

degrees = [v.degree() for v in subgraph.nodes()]
print(degrees)  # Output: [2, 2, 2]

Fabric

Fabric is a high level Python library designed to execute shell commands remotely over SSH, yielding useful Python objects in return. It builds on top of Invoke (subprocess command execution and command-line features) and Paramiko (SSH protocol implementation), extending their APIs to complement one another and provide additional functionality.
