【问题描述】：

我有一个 json 文件。我想在 django python 中读取 json 文件。

Json 文件包含

{
    "ATM Cash" : ["withdrawal"],
    "Expense" :["fees","goods","stationery","purchase","material","telephone"],
    "Income" : ["salary","deposit","rewards"],
    "Payment" : ["tranfer","payment"],
    "Medical" : ["dr ", 
       "doctor","dr.","nursing","pharmacist","physician","hospital","medicine"],
    "Food/Restaurent" :["food","catering"],
    "Groceries" : ["big bazar"],
    "Shopping" : ["cloths"],
    "Mobile recharge" : ["airtel"],
    "Auto & Fuel" : ["fuel"],
    "Travel" : ["travel"],
    "General" : ["others"]
}

【解决方案1】：

如果是文件则使用json.load()like

import json
with open('path/to/file/file_name.json', 'r') as f:
    my_json_obj = json.load(f)

【解决方案2】：

import json 

    json_data = '{
        "ATM Cash" : ["withdrawal"],
        "Expense" :["fees","goods","stationery","purchase","material","telephone"],
        "Income" : ["salary","deposit","rewards"],
        "Payment" : ["tranfer","payment"],
        "Medical" : ["dr ", 
           "doctor","dr.","nursing","pharmacist","physician","hospital","medicine"],
        "Food/Restaurent" :["food","catering"],
        "Groceries" : ["big bazar"],
        "Shopping" : ["cloths"],
        "Mobile recharge" : ["airtel"],
        "Auto & Fuel" : ["fuel"],
        "Travel" : ["travel"],
        "General" : ["others"]
    }'


    data = json.loads(json_data)

只需这样做，但请先按照基本教程进行操作。

【讨论】：

您的答案是正确的，因为 json_data 在您的情况下是一个字符串。他想从文件中读取它。所以他应该使用 json.load() 而不是 json.loads()。顺便说一句，如果您不喜欢回答新手发布的问题，那么您可以跳过它而不是沮丧。

【解决方案3】：

import json
def read_file(path):
    file = open(path, "r")
    data = file.read()
    file.close()
    return data

def read_json(path):
    return json.loads(read_file(path))

def write_json(path, data):
     return write_file(path, json.dumps(data))

def write_file(path, data):
   file = open(path, "w")
   file.write(str(data))
   file.close()
   return data

我发现这些由 MkNxGn 创建的函数对于写入和读取文件非常有用，包括 json 中的文件。
