PYYAML学习笔记

• 列表：成员相同缩进，以’- '开头（有空格）

--- # 一个美味水果的列表 - Apple - Orange - Strawberry - Mango 

• 字典:一个字典是由一个简单的 键: 值 的形式组成(冒号后面必须有一个空格):

--- # 一位职工的记录 name: Example Developer job: Developer skill: Elite # 另一种形式 {name: Example Developer, job: Developer, skill: Elite} 

• 注意事项
  • 有冒号的字典，需要加引号否则会导致语法错误。

foo: "somebody said I should put a colon here: so I did"

yaml.load

name: Tom Smith age: 37 spouse:     name: Jane Smith     age: 25 children:  - name: Jimmy Smith    age: 15  - name1: Jenny Smith    age1: 12 

import yaml f = open(r'test_config.yml') y = yaml.load(f) print (y) 

解决一个 warning

:YAMLLoadWarning: calling yaml.load() without Loader=… is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
y = yaml.load(f)

语法更新造成的，不影响使用。
解决办法： https://blog.csdn.net/rp517045939/article/details/88838417
改为y = yaml.load(list, Loader=yaml.FullLoader)
下面是一些其他模式

最终代码

import yaml with open(r'test_config.yml') as f:     y = yaml.load(f, Loader=yaml.FullLoader)     print(y)
