如何使用 python 将数据转储到 Json 文件中

How to dump data into Json file using python

如何将数据转储到 Json 文件 *正如在下面的 python 代码中看到的,我正在尝试在 Json 文件中转储数据,但我在 python 代码 *

中努力做到这一点
import time
import json
import os


def long_function(name):
    cache_path = 'cache.json'
    if not os.path.isfile(cache_path):
        with open(cache_path, 't') as json_file:
            cache_file_data = [name]
            jsondump(cache_file_data, json_file)
    else:
        with open(cache_path, 'r') as json_file:
            cache_file_data = json.load(json_file)

    if name in cache_file_data:
        print("Name already exist")
        return name
    else:
        cache_file_data.append(name)
        for e in range(5):
            time.sleep(1)
            print(e+1)
        with open(cache_path, 'w') as json_file:
            jsondump(cache_file_data, json_file)
            print("New Name added in cache")
            return name


print(long_function('nitu'))

所以请解决我的问题......请帮助我

这只不过是遵循这种模式,所以你的代码错误是..你没有在 if 条件下正确定义文件模式

with open (cache_path. "t") as json_file:

而不是

with open (cache_path. "w") as json_file:

第二件事是你没有做转储数据

import json
  
# JSON data:
x =  '{ "organization":"New_holn",
        "city":"Noida",
        "country":"India"}'
 
# python object to be appended
y = {"pin":117845}
 
# parsing JSON string:
z = json.loads(x)
  
# appending the data
z.update(y)
 
# the result is a JSON string:
print(json.dumps(z))
