json.dump() to write Json output to file by using python file objects

By using file object in Python we can write Json formatted data to a file using dump() method.

Using List

import json
my_list=['Alex','Ronald','Ronny']

fob=open('data_j3.txt','w')
json.dump(my_list, fob)
fob.close()

Using Dictionary

import json
my_dict={1:'Alex',2:'Ronald',3:'Ronny'}
with open("data_j2.json", "w") as fob:
    json.dump(my_dict, fob)
fob.close()

import json
my_dict={1:'Alex',2:'Ronald'}

fob=open('data_j.txt','w')
json.dump(my_dict, fob)
fob.close()

From URL to Json file

import json
from urllib.request import urlopen
url="https://www.plus2net.com/php_tutorial/student.json"  
f=urlopen(url)   # open 
data=json.load(f) # data collected 
fob=open('E:\\my_data\\data_j.json','w')
json.dump(data, fob)
fob.close()

All above scripts will create text files and these files can be checked for Json data format. Here is one sample code to read the data from a file.

fob=open('data_j2.json','r')
print(fob.read()) # {"1": "Alex", "2": "Ronald", "3": "Ronny"}
fob.close()

ensure_ascii Parameter: Use ensure_ascii=False to handle non-ASCII characters in the output.

import json
data = {"name": "José", "country": "España"}
with open("E:\\data.json", "w", encoding="utf-8") as file:
    json.dump(data, file, ensure_ascii=False)
