將json.load的unicode轉化為encode

json.load(file)讀取的文件內容為Unicode，需要將該數據轉為encode

def byteify(input):
    """把Unicode轉換為encode"""
    if isinstance(input, dict):
        return {byteify(key):byteify(value) for key,value in input.iteritems()}
        print("dic...dict")
    elif isinstance(input, list):
        return [byteify(element) for element in input]
        print("list...list...")
    elif isinstance(input, unicode):
        return input.encode('utf-8')
        print("unicode....unicode")
    else:
        return input
