如何更改索引或读取键的特定值,键的发生是否动态变化?

标签: python python-3.x dictionary yaml swagger

我有一个代码可以从YAML文件中捕获与以下键相关联的值。我已经将JSON文件转换为dict函数并读取了值。某个时刻,密钥的出现次数/行号会根据我选择的YAML文件而有所不同。

Keys:
In
Name
required
type

即使YAML文件中出现的行号发生更改,也需要帮助来获得标准代码/自定义现有代码。

在我尝试解析的示例YAML内容下方给出。由于该事件在一个API端点之间会有所不同。

我写了下面的代码来捕获基于索引[0]的值,但是索引值是动态的。 0处的示例出现关键字时,下一个内容可能出现在5点。

import yaml
import json
with open("pets.yaml", 'r') as yaml_in, open("yml_test.json", "w") as json_out:
    data = json.loads(json.dumps(yaml.load(yaml_in, Loader=yaml.FullLoader)))
    output_dict = {}
    for url in data["paths"]:
        for method in data["paths"][url]:
            output_dict[url + "/" + method] = {}
            output_dict[url + "/" + method]["parameters"] = {}
            if "consumes" in data["paths"][url][method]:
                output_dict[url+"/"+method]["consumes"] = data["paths"][url][method]["consumes"]
                print("Consumes Parameter: ", data["paths"][url][method]["consumes"])
            if "produces" in data["paths"][url][method]:
                output_dict[url+"/"+method]["produces"] = data["paths"][url][method]["produces"]
                print("Produces parameter: ", data["paths"][url][method]["produces"])
            if data["paths"][url][method]["parameters"]:
                if "in" in data["paths"][url][method]["parameters"][0]:
                    output_dict[url+"/"+method]["parameters"]["in"] = data["paths"][url][method]["parameters"][0]["in"]
                    print("In Parameter: ", data["paths"][url][method]["parameters"][0]["in"])
                if "name" in data["paths"][url][method]["parameters"][0]:
                    output_dict[url+"/"+method]["parameters"]["name"] = data["paths"][url][method]["parameters"][0]["name"]
                    print("Name parameter: ", data["paths"][url][method]["parameters"][0]["name"])
                if "required" in data["paths"][url][method]["parameters"][0]:
                    output_dict[url+"/"+method]["parameters"]["required"] = data["paths"][url][method]["parameters"][0]["required"]
                    print("Required Parameter: ", data["paths"][url][method]["parameters"][0]["required"])
                if "type" in  data["paths"][url][method]["parameters"][0]:
                    output_dict[url+"/"+method]["parameters"]["type"] = data["paths"][url][method]["parameters"][0]["type"]
                    print("Type Parameter: ", data["paths"][url][method]["parameters"][0]["type"])

    json.dump(output_dict, json_out)

下面是示例输出,但是我需要捕获所需的名称,类型。

当我将索引0更改为5时,发生以下输出。但是对于下一次出现,它可能在6或7或3之内,...

Produces parameter:  ['application/json']
In Parameter:  query
Produces parameter:  ['application/octet-stream']
In Parameter:  path
