Python JSON: Convert Python objects into JSON strings. Print all the values
Python JSON: Exercise-3 with Solution
Write a Python program to convert Python objects into JSON strings. Print all the values.
Sample Solution:-
Python Code:
import json
python_dict = {"name": "David", "age": 6, "class":"I"}
python_list = ["Red", "Green", "Black"]
python_str = "Python Json"
python_int = (1234)
python_float = (21.34)
python_T = (True)
python_F = (False)
python_N = (None)
json_dict = json.dumps(python_dict)
json_list = json.dumps(python_list)
json_str = json.dumps(python_str)
json_num1 = json.dumps(python_int)
json_num2 = json.dumps(python_float)
json_t = json.dumps(python_T)
json_f = json.dumps(python_F)
json_n = json.dumps(python_N)
print("json dict : ", json_dict)
print("jason list : ", json_list)
print("json string : ", json_str)
print("json number1 : ", json_num1)
print("json number2 : ", json_num2)
print("json true : ", json_t)
print("json false : ", json_f)
print("json null ; ", json_n)
Output:
json dict : {"name": "David", "age": 6, "class": "I"} jason list : ["Red", "Green", "Black"] json string : "Python Json" json number1 : 1234 json number2 : 21.34 json true : true json false : false json null ; null

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")
