Question

我的代码

with open('res1536.json', 'r') as json_file:
    json_data = json.load(json_file)

for group in json_data['resources']:
    group['slot'] = 0
    group['slot'] += 1


with open("RES_Edited.JSON", 'w') as json_edited:
             json.dump(json_data, json_edited, indent = 1)

但是它保存所有的插槽，例如“ slot”：1 我希望它将是“插槽”：1 “广告位”：2 “广告位”：3 ...

谢谢！

在循环时进行计数的一个好方法是enumerate。文件：http://book.pythontips.com/en/latest/enumerate.html

with open('res1536.json', 'r') as json_file:
    json_data = json.load(json_file)

for i, group in enumerate(json_data['resources']):
    group['slots'] = i


with open("RES_Edited.JSON", 'w') as json_edited:
             json.dump(json_data, json_edited, indent = 1)

您可以明确地执行以下操作：

i = 0
for group in json_data['resources']:
    group['slots'] = i
    i += 1

如何将每个json值增加1？
