python, json type write - how can i use \n on dictionary value?

python dictionary
json to python dict online
python object to json
python print json
python json bytes
python list to json
python custom json encoder
python create json array

i create dic type value, and here is my code

date = ["2015 1 3", "2015 1 3", "2015 1 3"]
des  = ["btcarchitect coinkite blockchain circlebits...", "swiftstealth offers you privacy in  bitswift v2 ...", "all in one article  bitcoin blockchain ..."]

for i in range(3) :
    dic = {"date":date[i], "description":des[i]}

with open('j.json', 'a', encoding='UTF-8-sig') as f:
        f.write(json.dumps(dic, indent=2, ensure_ascii=False))
    print (json.dumps(dic, indent=2, ensure_ascii=False) )

when i print this value, it works fine but f.write this 'dic' value, there is no \n on each tuple

here is result of print (dic)

{
  "date": "2015 1 3",
  "description": "btcarchitect coinkite blockchain circlebits..."
}
{
  "date": "2015 1 3",
  "description": "swiftstealth offers you privacy in  bitswift v2 ..."
}
{
  "date": "2015 1 3",
  "description": "all in one article  bitcoin blockchain ..."
}

and my json file is saved like this,

{
  "date": "2015 1 3",
  "description": "btcarchitect coinkite blockchain circlebits..."
}{
  "date": "2015 1 3",
  "description": "swiftstealth offers you privacy in  bitswift v2 ..."
}{
  "date": "2015 1 3",
  "description": "all in one article  bitcoin blockchain ..."
}

how can i save this end of } , and \n { ?

You can simply add \n to end of each line. Here's how to write:

outputFile=open('somefile.txt','a')
for i in range(3) :
    dic = {"date":date[i], "description":des[i]}
    outputFile.write(json.dumps(dic) + '\n')
outputFile.close()

19.2. json — JSON encoder and decoder, json exposes an API familiar to users of the standard library marshal and pickle modules Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object) using this Keys in key/value pairs of JSON are always of the type str. As a result of this, if a dictionary is converted into JSON and then back into a  JSON stands for JavaScript Object Notation. It means that JSON is a script (executable) file, which is made of text in the programming language, is used to save and transfer the data. Python supports JSON through an inbuilt package called json package. How to convert JSON to dict in Python. You can parse the JSON string using json.loads() method

import json
date = ["2015 1 3", "2015 1 3", "2015 1 3"]
des  = ["btcarchitect coinkite blockchain circlebits...", "swiftstealth offers you privacy in  bitswift v2 ...", "all in one article  bitcoin blockchain ..."]

dicts = []
for i in range(3) :
    dic = {"date":date[i], "description":des[i]}
    dicts.append(dic)

file=open('json.txt','a')
for i in dicts:
    file.write(json.dumps(i))
    file.write('\n')
file.close()

Using dictionaries to store data as key-value pairs, The dictionary stores objects as key-value pairs and can be used to represent complex unordered; Versatility as a data format; Dictionaries in the wild; JSON as data Just like the list object can contain a sequence of any kind of Python object, writing that kind of ugly forest of conditional-branches, especially for such a . Parameter: It takes JSON file as the parameter. Return type: It returns the python dictionary object. Example 1: Let’s suppose the JSON file looks like this: We want to convert the content of this file to Python dictionary.

Try the below. Similar idea as psychoCoder. -

import json

date = ["2015 1 3", "2015 1 3", "2015 1 3"]
des  = ["btcarchitect coinkite blockchain circlebits...", "swiftstealth offers you privacy in  bitswift v2 ...", "all in one article  bitcoin blockchain ..."]

with open('j.json', 'a') as f:
    for i in range(3) :
        dic = {"date":date[i], "description":des[i]}
        f.write(json.dumps(dic, indent=2, ensure_ascii=False))
        f.write("\n")
        print (json.dumps(dic, indent=2, ensure_ascii=False) )

It's common to transmit and receive data between a server and web application in JSON format. In Python, JSON exists as a string. For example: p = ' {"name": "Bob", "languages": ["Python", "Java"]}'.

Convert JSON to dictionary in Python, To use this feature, we import the json package in Python script. Return type: It returns the python dictionary object. for printing the key-value pair of print ( "\​nPrinting nested dicitonary as a key-value pair\n" ) GeeksforGeeks and would like to contribute, you can also write an article using contribute.geeksforgeeks.org​  Introduction of JSON in Python : The full-form of JSON is JavaScript Object Notation. It means that a script (executable) file which is made of text in a programming language, is used to store and transfer the data. Python supports JSON through a built-in package called json. To use this feature, we import the json package in Python script.

Python, json.dumps() is an inbuilt function in json library. print ( type (test1)). print ( "​initial dictionary = " The str() function converts the specified value into a string. filter_none Python code to demonstrate. # to convert dictionary into string. # using str() using str. result = str (test1). # print resulting string. print ( "\n" , type (​result)). Python and JSON. Python makes it simple to work with JSON files. The module used for this purpose is the json module. This module should be included (built-in) within your Python installation, and you thus don't need to install any external modules as we did when working with PDF and Excel files, for instance.

Reading and Writing JSON in Python, The same information can be represented using JSON as follows: type(person) # notice the type of data returned by load() <class 'dict'> > is also a string and is used to separate keys and values in a dictionary. By default  Let’s look at the differences between the JSON object and the python dictionary. The ‘won_grammy’ value in the JSON object is ‘false’, while in the dictionary it is a capitalized ‘False’. Additionally, the ‘album_sale’ ‘value Null’ was parsed as ‘None’ in the python dictionary.

Comments
  • f.write('\n')?
  • Please don't include pictures of code, ideally it should be in text. But what you're trying to create is JSON Lines
  • Try removing indent=2 and just dump the raw string
  • @zvone it doesn't works.
  • @roganjosh i edited it. and how can i create new json line?
