Python YAML:控制输出格式 [英] Python YAML: Controlling output format

问题描述

我的文件读取用户输入(如用户ID，密码..).并将数据设置为x.yml文件.

My file reads user input (like userid, password..). And sets the data to x.yml file.

x.yml文件的内容为

The content of x.yml file is

{user: id}

但是我希望内容保持原状

But instead I want the content to be as

user: id

我该如何实现?

推荐答案

如评论中所述，python YAML库是完成此任务的正确工具.要获得所需的输出，您需要将关键字参数 default_flow_style = False 传递给 yaml.dump :

As mentioned in the comments, the python YAML library is the right tool for the job. To get the output you want, you need to pass the keyword argument default_flow_style=False to yaml.dump:

>>> x = {"user" : 123}
>>> with open("output_file.yml", "w") as output_stream:
...     yaml.dump(x, output_stream, default_flow_style=False)

文件"output_file.yml"将包含:

The file "output_file.yml" will contain:

user: 123
