function. The json.loads()
is a built-in Python function that accepts a valid json string and returns a dictionary to access all elements. The json.loads()
function is used to parse valid JSON string into dictionary.
import json
s = '''{
"name":"Android",
"version":13
}'''
d = json.loads(s)
print(d)
print(json.loads('"\\"foo\\bar"'))
{u'version': 13, u'name': u'Android'} "foar

function.

The json.tool module provides a simple command line interface to validate and pretty-print JSON objects.
Command line options:infileThe JSON file to be validated or pretty-printed.outfileWrite the output of the infile to the given outfile. Otherwise, write it to sys.stdout.--sort-keysSort the output of dictionaries alphabetically by key.--no-ensure-asciiDisable escaping of non-ascii characters, see json.dumps() for more information.--json-linesParse every input line as separate JSON object.--indent, --tab, --no-indent, --compactMutually exclusive options for whitespace control.-h, --helpShow the help message.
