Read_yaml_file函数返回所有数据到字典中。

def read_yaml_file(full_path=None, relative_path=None):
    if relative_path is not None:
        resource_file_location_local = ProjectPaths.get_project_root_path() + relative_path
    else:
        resource_file_location_local = full_path

    with open(resource_file_location_local, 'r') as stream:
        try:
            file_artifacts = yaml.safe_load(stream)
        except yaml.YAMLError as exc:
            print(exc)
    return dict(file_artifacts.items())

像这样访问YAML文件中列表的任何元素:

global:
  registry:
    url: dtr-:5000/
    repoPath:
  dbConnectionString: jdbc:oracle:thin:@x.x.x.x:1521:abcd

您可以使用以下python脚本:

import yaml

with open("/some/path/to/yaml.file", 'r') as f:
    valuesYaml = yaml.load(f, Loader=yaml.FullLoader)

print(valuesYaml['global']['dbConnectionString'])

不依赖C头文件的最简单和最纯粹的方法是PyYaml(文档)，可以通过pip install PyYaml安装:

#!/usr/bin/env python

import yaml

with open("example.yaml", "r") as stream:
    try:
        print(yaml.safe_load(stream))
    except yaml.YAMLError as exc:
        print(exc)

就是这样。普通的yaml.load()函数也存在，但是应该始终优先使用yaml.safe_load()，以避免引入任意代码执行的可能性。因此，除非显式地需要任意对象序列化/反序列化，否则请使用safe_load。

注意PyYaml项目支持YAML 1.1规范的更高版本。如果需要YAML 1.2规范支持，请参阅ruamel。Yaml在这个答案中提到。

此外，您还可以使用一个替换pyyaml的drop，它可以使您的yaml文件保持原样，称为oyaml。在这里查看oyaml的synk

首先使用pip3安装pyyaml。

然后导入yaml模块并将文件加载到名为'my_dict'的字典中:

import yaml
with open('filename.yaml') as f:
    my_dict = yaml.safe_load(f)

这就是你所需要的。现在整个yaml文件都在'my_dict'字典中。
