标签异常

引发异常时，可以添加一个标签，它将替换你想用什么替换。

示例 yaml_snippet

a: 1
b:
  - 1
  - 2

from strictyaml import Map, Int, load, YAMLValidationError

标签 myfilename

load(yaml_snippet, Map({"a": Int(), "b": Map({"x": Int(), "y": Int()})}), label="myfilename")

strictyaml.exceptions.YAMLValidationError:
when expecting a mapping
  in "myfilename", line 2, column 1:
    b:
    ^ (line: 2)
found a sequence
  in "myfilename", line 4, column 1:
    - '2'
    ^ (line: 4)
