从python文件中获取字典

  • 772

我有一个包含以下信息的 txt 文件：

- name: python-3.8.9-amd64.exe\n
  link: https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd64.exe\n
  sha256summ: e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6\n
- name: python-3.8.9-amd645.exe\n
  link: https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd645.exe\n
  sha256summ: e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6

比如重复两次，可以是无限的，我需要name: link: sha256sum:在循环中获取一个包含better的列表，为了进一步处理列表，我不需要保存它

python yaml

    从外观上看，这个文件的格式是YAML。Set pyyaml( pip install pyyaml)，那么它实际上是在一个动作中解析的：

    file = """
- name: python-3.8.9-amd64.exe\n
  link: https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd64.exe\n
  sha256summ: e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6\n
- name: python-3.8.9-amd645.exe\n
  link: https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd645.exe\n
  sha256summ: e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6
"""

import yaml
from pprint import pprint

pprint(yaml.safe_load(file))

    结论：

    [{'link': 'https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd64.exe',
  'name': 'python-3.8.9-amd64.exe',
  'sha256summ': 'e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6'},
 {'link': 'https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd645.exe',
  'name': 'python-3.8.9-amd645.exe',
  'sha256summ': 'e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6'}]
