json.load()用于加載文件。json.loads()與字符串一起使用。

我正在嘗試從json文件讀取。

這是我創(chuàng)建文件的方式：

import requestsimport jsonimport timefrom pprint import pprintBASE_URL = 'https://www.wikiart.org/en/api/2/UpdatedArtists'artist_json_data = requests.get(BASE_URL).json()with open(’artistdata.json’,’w’) as outfile: while artist_json_data[’hasMore’]:print(artist_json_data[’paginationToken’])url = BASE_URL + '?paginationToken=' +artist_json_data[’paginationToken’]artist_json_data = requests.get(url).json()json.dump(artist_json_data,outfile,indent=4)time.sleep(1)

這是我輸出的開始：

{ 'data': [{ 'id': '57726da5edc2cb3880b4ca54','artistName': 'Paul Feeley','url': 'paul-feeley','lastNameFirst': 'Feeley Paul','birthDay': '/Date(-1893456000000)/','deathDay': '/Date(-126230400000)/',

當我嘗試使用以下代碼讀取同一文件時：

from pprint import pprintwith open(’artistdata.json’,’r’,encoding=’utf-8’) as data_file:data = json.loads(data_file) pprint(data)

我得到錯誤

TypeError: the JSON object must be str,bytes or bytearray,not ’TextIOWrapper’

我不明白，因為我可以像往常一樣崇高地打開文件。我該如何處理？

問題是我混合了轉(zhuǎn)儲和負載。現(xiàn)在我正在使用轉(zhuǎn)儲和加載
