我試圖找到一個合適的腳本來遍歷 .json 檔案的檔案夾并更新一行。
下面是一個位于路徑中的示例 json 檔案。我想遍歷一個檔案夾中的 json 檔案，該檔案夾包含多個這樣的檔案，其中包含各種資訊，并將“seller_fee_basis_points”從“0”更新為“500”并保存。
非常感謝您的幫助。

由于@JCaesar 的幫助，更新了答案
import json
import glob
import os
SOURCE_DIRECTORY = r'my_favourite_directory'
KEY = 'seller_fee_basis_points'
NEW_VALUE = 500
for file in glob.glob(os.path.join(SOURCE_DIRECTORY, '*.json')):
json_data = json.loads(open(file, encoding="utf8").read())
# note that using the update method means
# that if KEY does not exist then it will be created
# which may not be what you want
json_data.update({KEY: NEW_VALUE})
json.dump(json_data, open(file, 'w'), indent=4)
uj5u.com熱心網友回復：
我建議使用glob來查找您感興趣的檔案。然后使用json模塊來讀取和寫入 JSON 內容。
這是非常簡潔的，沒有健全性檢查/例外處理，但你應該明白：
import json
import glob
import os
SOURCE_DIRECTORY = 'my_favourite_directory'
KEY = 'seller_fee_basis_points'
NEW_VALUE = 500
for file in glob.glob(os.path.join(SOURCE_DIRECTORY, '*.json')):
json_data = json.loads(open(file).read())
# note that using the update method means
# that if KEY does not exist then it will be created
# which may not be what you want
json_data.update({KEY: NEW_VALUE})
json.dump(json_data, open(file, 'w'), indent=4)
