1. What Type of Language is the Python Programming Language?
Python is defined as an interpreted, high–level, and a general-purpose programming language. The language was made with an emphasis on code readability and with the use of significant indentation.
Python language object-oriented approach focus on helping programmers to write clear and more logical code for small and large-scale projects.
Additionally, Python is dynamically-typed and garbage-collected programming language. That means that it supports multiple programming paradigms, structured, procedural, object-oriented and functional programming. Python language is normally described as a a batteries included language based on its comprehensive standard library.
2. Is Python a Programming Language or a Scripting Language?
Python is a programming language because it lets you program a computer to carry out your instructions. It is also a scripting language because it lets you write your Python programs in the form of scripts. That means unlike other programming languages that must first be compiled and completely debugged before being converted into executables and only then executed. Python language is therefore both a programming language and a scripting language.
3. What are the Python Programming Language Key Features?
a) Python is an object-oriented programming language. Everything in a python is in the form of an object. Python supports inheritance, encapsulation and polymorphism.
b) Python is a dynamically typed language. This means there is no need to declare a type of variable. It is decided at run time.
c) Python uses a Graphical User Interface to develop desktop applications. There are many modules available in python like PyQT5, Tkinter, Kivy etc. to develop applications.
d) Python is an Interpreted Language. Its code is executed line by line. Because of this, there is no need to worry about linking to libraries, syntax, and type checking which makes it easy to debug the code.
e) Python is free and open source freely available to download, install and use from python.org. Libraries of python are open source. Anyone could use modules and functions of python.
f) Python is a high-level language. It uses a common English language for coding that is more understandable to the user.
g) Python is a portable language. it is called cross-platform language. The language run on various platforms without changing the code.
h) Python supports a large number of standard libraries for regular expression, web browsers, databases, image processing, unit testing, and others.
i) Python automatically assigns memory to the variable. There is no need to declare data type.
j) Python is an Extensible language. Python code can be written into C or C++ language and also be compiled in C/C++ language.
k) Python is an Integrated language because it can easily be integrated with other languages like C and C++.
l) Python supports automatic garbage collection. Memory block that is no longer used free by the garbage collector gets to be deleted as unwanted objects to free more memory space.
4. What are the Python Modules?
A Python module is a file containing Python definitions and statements. A module is used to define functions, classes, runnable code, and variables. We can import the functions, classes defined in a module to another module using the import statement. The advantage of modules is that it helps in grouping related code into a module. The grouping makes it very easy for the one to easily understand and use code. Furthermore, it also makes the code logically organized.
5. What is __init__?
The “What is __init__“ allows the Python interpreter to know that a directory contains code for a Python module. For instance an __init__.py file can be blank. The “What is __init__” file is used to import modules from another folder into your project. Every classes have a function called __init__(), the function is usually executed when the class is being initiated. The __init__() function is always called automatically every time the class is being used to create a new object.
