Objects in real-world and programming

OBJECTS IN REAL-WORLD AND PROGRAMMING

In object-oriented programming, an object is a real-world entity. In object-oriented programming, it is said that an object is a real-world entity. If we talk about our surroundings, how do we define an object? We would say that; an object is any living or non-living thing in our surroundings. There is a special thing about an object that is an object is never static, it keeps changing. There are always two features of an object, behavior and its properties. Behaviors mean for what task it is used and the properties are its physical appearance. The best example of this would be an isolated room. If you close a room from all sides for 2-3 days or more and come back, then you will find some changes in every object present in the room. Those changes can be very minute, but there will be changes. For example, dust can be present over things. When we closed the room, there was no dust. This shows that an object always keeps changing.

That is why it is said that an object is a real-world entity and that is why languages which are object-oriented are said to be better.

What Are The Classes?

A class in object-oriented programming is defined as the collection of member functions and member variables. A class is also known as the collection of the objects. Member functions, as well as member variables, are those variables and functions which are declared inside a class. That is why the word member is used as these are the members of the class. In an object-oriented language, not a single line of code can be written outside a class.

WHAT IS A COMPILER?

A compiler is responsible for checking the line of codes and finding errors in lines of code. A compiler checks the code page wise. A compiler always checks the whole page first and then shows the errors.

WHAT IS AN INTERPRETER?

A compiler is also responsible for finding errors in the program. An interpreter checks the code line by line. An interpreter checks a single line and if it finds any error in it, then it will show those errors to the user immediately and do not show the output of the next line until the shown error is resolved.

Interpreters and Compilers Used by Python

Python uses an interpreter by default. However, we can use the compiler as well as an interpreter in the Python. Here are some interpreters and compilers which are used by the Python. They are listed below:

• CPython (It is an interpreter)
• Jython (It is a compiler which is used for compiling the Java code in Python)
• IronPython (It is a compiler which is used for compiling the.NET code in Python)
• Nuitka (It is a compiler)
• StacklessPython (It is an interpreter)
