检测文件的格式——chardet模块

 f3 = open(file=path,mode='rb')
        data = f3.read()
        # print(data)
        f3.close()

        result = chardet.detect(data)
        print(result)

结果：

{'encoding': 'Big5', 'confidence': 0.99, 'language': 'Chinese'}

f3 = open(file=cfgpath, mode='rb')
        data = f3.read()
        f3.close()

        result = chardet.detect(data)['encoding']

结果：

utf-8
