1. 安裝yaml庫
想要使用python實現yaml與json格式互相轉換，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得安裝與使用，解決pip下載速度慢得問題
安裝yaml庫：
pip install pyyaml
2. yaml轉json
新建一個test.yaml文件，添加以下內容：
A: hello: name: Michael address: Beijing B: hello: name: jack address: Shanghai
代碼如下：
import yamlimport json# yaml文件內容轉換成json格式def yaml_to_json(yamlPath): with open(yamlPath, encoding="utf-8") as f: datas = yaml.load(f,Loader=yaml.FullLoader) # 將文件得內容轉換為字典形式 jsonDatas = json.dumps(datas, indent=5) # 將字典得內容轉換為json格式得字符串 print(jsonDatas)if __name__ == "__main__": jsonPath = 'E:/Code/Python/test/test.yaml' yaml_to_json(jsonPath)
執行結果如下：
{
"A": {
"hello": {
"name": "Michael",
"address": "Beijing"
}
},
"B": {
"hello": {
"name": "jack",
"address": "Shanghai"
}
}
}
3. json轉yaml
新建一個test.json文件，添加以下內容：
{ "A": { "hello": { "name": "Michael", "address": "Beijing" } }, "B": { "hello": { "name": "jack", "address": "Shanghai" } }}代碼如下：
import yamlimport json# json文件內容轉換成yaml格式def json_to_yaml(jsonPath): with open(jsonPath, encoding="utf-8") as f: datas = json.load(f) # 將文件得內容轉換為字典形式 yamlDatas = yaml.dump(datas, indent=5, sort_keys=False) # 將字典得內容轉換為yaml格式得字符串 print(yamlDatas)if __name__ == "__main__": jsonPath = 'E:/Code/Python/test/test.json' json_to_yaml(jsonPath)
執行結果如下：
A:
hello:
name: Michael
address: Beijing
B:
hello:
name: jack
address: Shanghai
注意，如果不加sort_keys=False，那么默認是排序得，則執行結果如下：
A:
hello:
address: Beijing
name: Michael
B:
hello:
address: Shanghai
name: jack
4. 批量將yaml與json文件互相轉換
yaml與json文件互相轉換：
import yamlimport jsonimport osfrom pathlib import Pathfrom fnmatch import fnmatchcaseclass Yaml_Interconversion_Json: def __init__(self): self.filePathList = [] # yaml文件內容轉換成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文件內容轉換成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得文件 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得文件 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得文件 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() # 批量刪除指定文件夾下所有相同后綴名得文件 def batch_remove_file_suffix(self, dirPath, suffix): self.search_file_suffix(dirPath, suffix) 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() # 批量將目錄下得yaml文件轉換成json文件 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: self.generate_json_file(yamPath) except Exception as e: print('YAML parsing error：{}'.format(e)) self.clear_list() # 批量將目錄下得json文件轉換成yaml文件 def batch_json_to_yaml(self, dirPath): self.search_file_suffix(dirPath, 'json') print('The converted json file is as follows：{}'.format(self.filePathList)) for jsonPath in self.filePathList: try: self.generate_yaml_file(jsonPath) except Exception as e: print('JSON parsing error：{}'.format(jsonPath)) print(e) self.clear_list()if __name__ == "__main__": dirPath = 'C:/Users/hwx1109527/Desktop/yaml_to_json' fileName = 'os_deploy_config.yaml' suffix = 'yaml' filePath = dirPath + '/' + fileName yaml_interconversion_json = Yaml_Interconversion_Json() yaml_interconversion_json.batch_yaml_to_json(dirPath) # yaml_interconversion_json.batch_json_to_yaml(dirPath) # yaml_interconversion_json.batch_remove_file_suffix(dirPath, suffix)到此這篇關于Python實現yaml與json文件批量互轉得內容就介紹到這了,更多相關Python yaml json互轉內容請搜索之家以前得內容或繼續瀏覽下面得相關內容希望大家以后多多支持之家！
