无法使用python读取json文件

Question

i am trying to read a json file that is the input for Mongodb. if i can edit a single record as a valid jason i am able to do so. but when i am trying to read the entire file, i am not able to do it. it shows me error.

Error message

I have done a base code like given below.

#!/usr/bin/python
# -*- coding: utf-8 -*-

import json 
# comment : Importing the json file to read;
database = "new 2.json"
data = json.loads(open(database).read())

# Comment : Variable Declaration;

# Comment : Display the json values;
for key,value in data.iteritems():
    if 'patient_id' == key:
        print("key: {0} | value: {1}".format(key, value))
    if 'name' == key:
        print("key: {0} | value: {1}".format(key, value))
    if 'age' == key:
        print("key: {0} | value: {1}".format(key, value))
    if 'gender' == key:
        print("key: {0} | value: {1}".format(key, value))
# for key,value in data.iteritems():
    if 'address' == key:
        print("key: {0} | value: {1}".format(key, value))
    # if 'labRecords' == key:
        # print("key: {0} | value: {1}".format(key, value))

i am able to print the data for a single record, that i have corrected into a proper json file. but for the others i need to modify all the records. is there any way to do it???

Answer 1

It looks like you are missing the second parameter to open which should be one of either:

a , r , w , rb , or wb

With the file test.json in the working directory, this works for me:

Test.json

{
  "foo": 1,
  "bar": 2,
  "baz": 3
}

Python script:

import json

with open("test.json", "rb") as f:
    data = json.load(f)


for key, value in data.items():
    print(key, value)

Output:

foo 1
bar 2
baz 3

Answer 2

You can try this.

import json
with open("json_data.json", mode='r', encoding='utf-8') as json_data:
    data = json.load(json_data)
    print(data)

json_data.json

 {
  "hello": 11,
  "world": 22,
  "json": 33
}

output

{'hello': 11, 'world': 22, 'json': 33}

make sure your json format data is ok. and check first you get the output as you want. and than you can proceed your further work.
