Python JSON: Convert JSON encoded data into Python objects

Python JSON: Exercise-5 with Solution

Write a Python program to convert JSON encoded data into Python objects.

Sample Solution:-

Python Code:

import json

jobj_dict =  '{"name": "David", "age": 6, "class": "I"}'
jobj_list =   '["Red", "Green", "Black"]'
jobj_string = '"Python Json"'
jobj_int = '1234'
jobj_float =  '21.34'
python_dict =  json.loads(jobj_dict)
python_list = json.loads(jobj_list)
python_str =  json.loads(jobj_string)
python_int =   json.loads(jobj_int)
python_float = json.loads(jobj_float)

print("Python dictionary: ", python_dict)
print("Python list: ", python_list)
print("Python string: ", python_str)
print("Python integer: ", python_int)
print("Python float: ", python_float)

Output:

Python dictionary:  {'name': 'David', 'age': 6, 'class': 'I'}
Python list:  ['Red', 'Green', 'Black']
Python string:  Python Json
Python integer:  1234
Python float:  21.34

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
