带有返回AttributeError的Python Json：__enter__

Question

为什么返回AttributeError：__enter__

排序方法只是根据列表的排序方式创建的字符串，当前时间使用stfttime

current_time = strftime("%Y-%m-%d %H-%M-%S", gmtime())

filename = f"Komplett-{str(sorting_method)}-{str(current_time)}.txt"
if not os.path.exists(f'C:/Users/tagp/OneDrive/Dokumenter/Python/{filename}'):
        open(str(filename), "w+")   
with (filename, "w+") as json_data:
            my_list = {}
            my_list["products"] = []
            for thing in my_products:
                my_list["products"].append({
                    "Product Title":thing.title,
                    "Price":thing.price,
                    "Rating":thing.rating,
                    "Stock":thing.stock
                    })
            json.dump(my_list, json_data, indent = 4)

完整回溯：

Traceback (most recent call last):
    File "komplett.py", line 172, in <module>
        with (filename, "w") as json_data:
AttributeError: __enter__

你只是为了使用开放

current_time = strftime("%Y-%m-%d %H-%M-%S", gmtime())

filename = f"Komplett-{str(sorting_method)}-{str(current_time)}.txt"
if not os.path.exists(f'C:/Users/tagp/OneDrive/Dokumenter/Python/{filename}'):
        open(str(filename), "w+")   
with open(filename, "w+") as json_data:
            my_list = {}
            my_list["products"] = []
            for thing in my_products:
                my_list["products"].append({
                    "Product Title":thing.title,
                    "Price":thing.price,
                    "Rating":thing.rating,
                    "Stock":thing.stock
                    })
            json.dump(my_list, json_data, indent = 4)
