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")
