python - Python中输出json txt名称

Question

我需要帮助将 .txt 输出文件的名称更改为 json 文件内的日期，这可能吗？

Json:

"date": "2018-03-21",

python :

import urllib.request, json

with urllib.request.urlopen("http://api.fixer.io/latest?&base=EUR") as url:
    data=json.loads(url.read().decode())
    print(data)

    with open('*changeNameHere*{}.txt'.format(*Example*), 'w') as outfile:
        json.dump(data["rates"], outfile)

简单地做:

import urllib.request, json

with urllib.request.urlopen("http://api.fixer.io/latest?&base=EUR") as url:
    data=json.loads(url.read().decode())
    print(data)

    with open('{}.txt'.format(data['date']), 'w') as outfile:
        json.dump(data["rates"], outfile)
