JSON in Python

-

 

v  JSON in Python: -

  • JSON stands for JavaScript Object Notation, which is a format for structuring data.

  • It is a widely used data format for storing and transferring data between a client and a server system.

  • It can be used with various programming languages such as Python, Perl, Java, etc.

  • Python supports JSON through a built-in package called Json. To use this feature, we import the JSON package in Python.

  •  The text in JSON is done through quoted strings, which contain the value in key-value mapping within { }, which is similar to a dictionary in Python.

  • JSON supports primitive types like numbers, strings, lists, nested lists, tuples and objects.

  • In Python, we can convert Python objects (like dictionaries and lists) into JSON strings; this process is called serialisation and also parse JSON data back into Python objects; this process is called deserialisation.

  • Python provides the following important methods in the JSON module:

1.      dump( )

2.      load( )

3.      dumps( )

4.      loads( )


1)    dump( ): -The json.dump( ) method is used to write a Python object to JSON data into a file.

Example                                                                                       





















                       output
 

2)    load( ): -json.load( ) method is used to read JSON data from a file and convert it into a Python object.

Example



Output: -

3)    dumps( ): -  json.dumps( ) method is used to convert a Python object like a dictionary or list into a JSON-formatted string.

Example                      


   output


4)  loads( ): - json.loads( ) method is used to convert a JSON string into a Python object.

Example

operators in c programming

v Operators: - An operator is a symbol that tells or intimates to the compiler to perform specific calculations or manipulations on one or more operands. Operators are essential for performing computations and making decisions in programs.   a + b is an operation a & b are operands + is an operator   Based on number of operands involved: 1.      Unary operators: - unary operators can be applied on only one operator. Example: -   ++ , -- , - (unary minus) , sizeof , ~ (compliment) , ! (not).   2.      Binary operators: - binary operators can be applied on two operands. Example: -   + , -,   * , / , etc.   3.    Ternary operators: - Ternary operator can be applied on three operands. Example: -   ?: (ternary conditional operator).   C supports several operators, can be classified into following...

Variables in c

  Variables: - A variable is a data name or an identifier which stores a value that can be changed during the program execution.  Every variable might belong to any of the data types, like int, float, char, etc.  The name of a variable can be composed of letters, digits, and the underscore character. It must begin with either a letter or an underscore.  Variables are case-sensitive because uppercase and lowercase letters are distinct. C programming language also allows defining various other types of variables, like numeric array, character array, pointer, Structure, Union, Enumeration and etc.               Example: - sum, height, _value Declaring a variable in C: - Variable declaration means telling the compiler about the name and type of a variable before using it in the program. Variable declaration is the process of reserving a memory location and defining the type of data that will be stored in that locatio...

Cloud Storage and Local Storage: Applications in Business

  Cloud Storage and  Local Storage: Applications in Business: -   Local Storage: - Local storage refers to storing data such as text, audio, video, graphics, animation, special characters, constants, mathematical expressions and numeric data on physical devices in our computer or other electronic devices. Local storage in business refers to storing business data such as customer contact information, sales records, financial statements, employee data, market research, operational metrics, raw information like customer feedback.  It can also stores the structured data, such as in spreadsheets, or unstructured, like text from surveys or social media post on physical devices like hard drives, SSDs, or company servers within the organization’s premises.  The business owns and manages the storage hardware.  Local storage provides faster access to large files, which is helpful for tasks like video editing, 3D rendering, and engineering design projects. It o...
