Python實(shí)現(xiàn)yaml與json文件批量互轉(zhuǎn)

這篇文章主要為大家詳細(xì)介紹了如何利用Python語言實(shí)現(xiàn)yaml與json文件的批量互轉(zhuǎn)，文中的示例代碼講解詳細(xì)，感興趣的小伙伴可以動手嘗試一下

1. 安裝yaml庫

想要使用python實(shí)現(xiàn)yaml與json格式互相轉(zhuǎn)換，需要先下載pip，再通過pip安裝yaml庫。

如何下載以及使用pip，可參考：pip的安裝與使用，解決pip下載速度慢的問題

安裝yaml庫：

pip install pyyaml

2. yaml轉(zhuǎn)json

新建一個(gè)test.yaml文件，添加以下內(nèi)容：

A:
     hello:
          name: Michael    
          address: Beijing 
          
B:
     hello:
          name: jack 
          address: Shanghai

代碼如下：

import yaml
import json

# yaml文件內(nèi)容轉(zhuǎn)換成json格式
def yaml_to_json(yamlPath):
    with open(yamlPath, encoding="utf-8") as f:
        datas = yaml.load(f,Loader=yaml.FullLoader)  # 將文件的內(nèi)容轉(zhuǎn)換為字典形式
    jsonDatas = json.dumps(datas, indent=5) # 將字典的內(nèi)容轉(zhuǎn)換為json格式的字符串
    print(jsonDatas)

if __name__ == "__main__":
    jsonPath = 'E:/Code/Python/test/test.yaml'
    yaml_to_json(jsonPath)

執(zhí)行結(jié)果如下：

{
"A": {
"hello": {
"name": "Michael",
"address": "Beijing"
}
},
"B": {
"hello": {
"name": "jack",
"address": "Shanghai"
}
}
}

3. json轉(zhuǎn)yaml

新建一個(gè)test.json文件，添加以下內(nèi)容：

{
    "A": {
         "hello": {
            "name": "Michael",
            "address": "Beijing"           
         }
    },
    "B": {
         "hello": {
            "name": "jack",
            "address": "Shanghai"    
         }
    }
}

代碼如下：

import yaml
import json

# json文件內(nèi)容轉(zhuǎn)換成yaml格式
def json_to_yaml(jsonPath):
    with open(jsonPath, encoding="utf-8") as f:
        datas = json.load(f) # 將文件的內(nèi)容轉(zhuǎn)換為字典形式
    yamlDatas = yaml.dump(datas, indent=5, sort_keys=False) # 將字典的內(nèi)容轉(zhuǎn)換為yaml格式的字符串
    print(yamlDatas)

if __name__ == "__main__":
    jsonPath = 'E:/Code/Python/test/test.json'
    json_to_yaml(jsonPath)

執(zhí)行結(jié)果如下：

A:
hello:
name: Michael
address: Beijing
B:
hello:
name: jack
address: Shanghai

注意，如果不加sort_keys=False，那么默認(rèn)是排序的，則執(zhí)行結(jié)果如下：

A:
hello:
address: Beijing
name: Michael
B:
hello:
address: Shanghai
name: jack

4. 批量將yaml與json文件互相轉(zhuǎn)換

yaml與json文件互相轉(zhuǎn)換：

import yaml
import json
import os
from pathlib import Path
from fnmatch import fnmatchcase

class Yaml_Interconversion_Json:
    def __init__(self):
        self.filePathList = []
    
    # yaml文件內(nèi)容轉(zhuǎn)換成json格式
    def yaml_to_json(self, yamlPath):
        with open(yamlPath, encoding="utf-8") as f:
            datas = yaml.load(f,Loader=yaml.FullLoader)  
        jsonDatas = json.dumps(datas, indent=5)
        # print(jsonDatas)
        return jsonDatas

    # json文件內(nèi)容轉(zhuǎn)換成yaml格式
    def json_to_yaml(self, jsonPath):
        with open(jsonPath, encoding="utf-8") as f:
            datas = json.load(f)
        yamlDatas = yaml.dump(datas, indent=5)
        # print(yamlDatas)
        return yamlDatas

    # 生成文件
    def generate_file(self, filePath, datas):
        if os.path.exists(filePath):
            os.remove(filePath)	
        with open(filePath,'w') as f:
            f.write(datas)

    # 清空列表
    def clear_list(self):
        self.filePathList.clear()

    # 修改文件后綴
    def modify_file_suffix(self, filePath, suffix):
        dirPath = os.path.dirname(filePath)
        fileName = Path(filePath).stem + suffix
        newPath = dirPath + '/' + fileName
        # print('{}_path：{}'.format(suffix, newPath))
        return newPath

    # 原yaml文件同級目錄下，生成json文件
    def generate_json_file(self, yamlPath, suffix ='.json'):
        jsonDatas = self.yaml_to_json(yamlPath)
        jsonPath = self.modify_file_suffix(yamlPath, suffix)
        # print('jsonPath：{}'.format(jsonPath))
        self.generate_file(jsonPath, jsonDatas)

    # 原json文件同級目錄下，生成yaml文件
    def generate_yaml_file(self, jsonPath, suffix ='.yaml'):
        yamlDatas = self.json_to_yaml(jsonPath)
        yamlPath = self.modify_file_suffix(jsonPath, suffix)
        # print('yamlPath：{}'.format(yamlPath))
        self.generate_file(yamlPath, yamlDatas)

    # 查找指定文件夾下所有相同名稱的文件
    def search_file(self, dirPath, fileName):
        dirs = os.listdir(dirPath) 
        for currentFile in dirs: 
            absPath = dirPath + '/' + currentFile 
            if os.path.isdir(absPath): 
                self.search_file(absPath, fileName)
            elif currentFile == fileName:
                self.filePathList.append(absPath)

    # 查找指定文件夾下所有相同后綴名的文件
    def search_file_suffix(self, dirPath, suffix):
        dirs = os.listdir(dirPath) 
        for currentFile in dirs: 
            absPath = dirPath + '/' + currentFile 
            if os.path.isdir(absPath):
                if fnmatchcase(currentFile,'.*'): 
                    pass
                else:
                    self.search_file_suffix(absPath, suffix)
            elif currentFile.split('.')[-1] == suffix: 
                self.filePathList.append(absPath)

    # 批量刪除指定文件夾下所有相同名稱的文件
    def batch_remove_file(self, dirPath, fileName):
        self.search_file(dirPath, fileName)
        print('The following files are deleted：{}'.format(self.filePathList))
        for filePath in self.filePathList:
            if os.path.exists(filePath):
                os.remove(filePath)	
        self.clear_list()

    def batch_yaml_to_json(self, dirPath):
        self.search_file_suffix(dirPath, 'yaml')
        print('The converted yaml file is as follows：{}'.format(self.filePathList))
        for yamPath in self.filePathList:
            try:
