• Có một số cách để cập nhật tệp JSON trong Python.Ở đây, tôi sẽ cung cấp cho bạn ví dụ rất đơn giản về tệp JSON chỉnh sửa bằng các hàm Open (), append (), dump () và đóng ().Vì vậy, hãy xem một ví dụ đơn giản dưới đây: bạn có thể sử dụng các ví dụ này với phiên bản Python3 (Python 3).edit JSON file using open(), append(), dump() and close() functions. so let's see a simple example below: You can use these examples with python3 (Python 3) version.json.loads() function is present in python built-in ‘json’ module. This function is used to parse the JSON string.
