Ques:- How the string does get converted to a number?
Asked In :-

Comments
• To convert the string into a number the built-in functions are used like int() constructor. It is a data type that is used like int (‘1’) ==1.
• float() is also used to show the number in the format as float(‘1’)=1.
• The number by default are interpreted as decimal and if it is represented by int(‘0x1’) then it gives an error as ValueError. In this the int(string,base) function takes the parameter to convert string to number in this the process will be like int(‘0x1’,16)==16. If the base parameter is defined as 0 then it is indicated by an octal and 0x indicates it as hexadecimal number.
• There is function eval() that can be used to convert string into number but it is a bit slower and present many security risks like __import__('os').system("rm -rf$HOME") - use of this will delete the home directory of the system.

Ques:- What are HTTP methods and how are they used in APIs
Asked In :-
Xoriant Solutions Pvt Ltd, KRIOS Info Solutions, Itobuz Technologies, Addweb solutions, Solace Infotech, TNQ Technologies, MatchMove India, Sun Technology Integrators, Spectra Medix India, Novalnet e-Solutions,
Right Answer:
HTTP methods are standardized request types used in APIs to perform actions on resources. The main methods are:
1. **GET**: Retrieve data from a server.
2. **POST**: Send data to a server to create a new resource.
3. **PUT**: Update an existing resource on the server.
4. **DELETE**: Remove a resource from the server.
5. **PATCH**: Apply partial modifications to a resource.
These methods define the action to be performed on the specified resource in the API.

Ques:- What are RESTful principles and how do they apply to API design
Asked In :-
STIC SOFT E-SOLUTIONS, Addweb solutions, Dhruvsoft Services, Elite Software Solutions, QUALYS SECURITY TECHSERVICES, Tredence Analytics Solutions, Spark Infosys, Noesys Consulting, Deligence Technologies, Technostacks Infotech,
Right Answer:
RESTful principles include:
1. **Statelessness**: Each API call must contain all the information needed to understand and process the request, with no stored context on the server.
2. **Client-Server Architecture**: The client and server are separate, allowing for independent development and scalability.
3. **Uniform Interface**: A consistent way to interact with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE).
4. **Resource-Based**: APIs should expose resources (data entities) through URIs, and clients interact with these resources.
5. **Representation**: Resources can be represented in various formats (like JSON or XML), and clients can request the format they prefer.
6. **Cacheability**: Responses should indicate whether they can be cached to improve performance and reduce server load.
These principles guide the design of APIs to be scalable, efficient, and easy to use.

Ques:- What is an API and how does it work
Asked In :-
Ziffity Solutions, Toxsl Technologies, Itobuz Technologies, LiteBreeze Infotech, TRICON INFOTECH PVT, Spectra Medix India, Muvi Entertainment, Tredence Analytics Solutions, NSOFT SOLUTIONS, Spark Infosys,
Right Answer:
An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs work by sending requests from one application to another, which then processes the request and sends back a response.
