We are currently coding of python C methods are being used. The base of all the libraries such as Numpy, Opencv, pytorch etc are built with the C and C++ i.e. these libraries internally call the Compiled C code where code will be executed in the machine and the result will be return in python wrapper. Why are we using the C methods in python? The reason why we are using the C method in python is the performance. The python performance will be decreased because of the dynamic typing. It has to reduce the type of operands to ... Read More

OOPs is abbreviated as object oriented programming language. It helps us to deal with the real time entities with inheritance, polymorphism, encapsulation etc. By using the oops concept we can make the code and functions work together in a better way. Group of objects is called a class. The class contains the blueprint, which takes as the reference to create the object. This contains attributes and methods in a logical entity. Now let’s see why we have to split the code into multiple classes. If we create the entire code in the single class, it will be easy to write ... Read More
There are different modules or packages in the python classes. When we use their names as it is in the code it will be somewhat clumsy and not good to see. So, we need to organize the python classes in modules and packages. Modules are the group of functions, classes or any block of code kept in a single file. The file extension of the methods will be .py. If the python code is with 300-400 lines of code, then it can be made as a module for better understandability. The module name can be available as ...
