我正在执行以下 python 代码:
import yaml
foo = {
'name': 'foo',
'my_list': [{'foo': 'test', 'bar': 'test2'}, {'foo': 'test3', 'bar': 'test4'}],
'hello': 'world'
}
print(yaml.dump(foo, default_flow_style=False))
但正在打印:
hello: world
my_list:
- bar: test2
foo: test
- bar: test4
foo: test3
name: foo
代替:
hello: world
my_list:
- bar: test2
foo: test
- bar: test4
foo: test3
name: foo
如何以这种方式缩进 my_list
元素?

This ticket建议当前的实现正确地遵循 the spec :
The “-”, “?” and “:” characters used to denote block collection entries are perceived by people to be part of the indentation. This is handled on a case-by-case basis by the relevant productions.
在同一个线程上,还有this code snippet (修改以适合您的示例)以获得您正在寻找的行为:
import yaml
class MyDumper(yaml.Dumper):
def increase_indent(self, flow=False, indentless=False):
return super(MyDumper, self).increase_indent(flow, False)
foo = {
'name': 'foo',
'my_list': [
{'foo': 'test', 'bar': 'test2'},
{'foo': 'test3', 'bar': 'test4'}],
'hello': 'world',
}
print yaml.dump(foo, Dumper=MyDumper, default_flow_style=False)
