如何通过Python在yaml文件中的一个标签下添加括号{}？

Question

I want to make one YAML file by Python like as below.

A:
  B:
     c: {d:e}

but if I do it like as below:

data = {'A':{'B':{ 'c':'{d:e}'}}}
yaml.dump(data,file,default_flow_style = False)

the output in the file is as below:

A:
  B:
    c: '{d: e}'

I don't want the quotation around. How to do it?

Answer 1

You made a string out of {d:e} by putting quotes around the whole thing. Change '{d:e}' to {'d':'e'} .

In [57]: data = {'A':{'B':{ 'c':{'d':'e'}}}}

In [58]: print yaml.dump(data)
A:
  B:
    c: {d: e}
