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")
