Python Introduction to Programming Language

Python Introduction: Python course provides basic and advanced concepts of python. Our Python Course is designed for beginners and professionals.

Python Language is a simple general-purpose high-level and object-oriented programming language.

Python is an interpreted scripting language also. Guido Van Rossum 1991 is known as the founder of the python programming language.

Our python course includes all topics of Python programming such as installation, control statements, strings, lists, tuples, dictionaries, modules, exceptions, date and time, file i/o, programs, etc.

There are also give python interview questions to help you better understand the python programming language.

History of Python Language

Python laid its foundation in the late 1980s. The implementation of python was started in December 1989 by Guido Van Rossum at CWI in Netherland.

1. February in 1991 Van Rossum published the code version 0.9.

2. Python 1.0 was released in 1994 with new features like lambda,

map, filter, and reduce.

3. Python 2.0 added new features like list comprehension, a garbage collection system.

4. Python 3.0 released on December 3, 2008, also called "py3K" was released. It was designed to rectify the fundamental flaws of language.

What is Python Programming Language?

Python is a general-purpose dynamic high-level and interpreted programming language. It supports an object-oriented programming approach to developing applications. It is simple and easy to learn and provides lots of high-level data structures.

Python is an easy to learn yet powerful and versatile scripting language, which makes it attractive for application development.

Python syntax and dynamic typing with its interpreted nature make it an ideal language for scripting and rapid application development.

Python supports multiple programming patterns, including object-oriented, imperative, and functional or procedural programming styles.

Python is not intended to work in a particular area, such as web programming. That is why it is known as a multipurpose programming language because it can be used with web, enterprise,3D CAD, etc.

We do not need to use data types to declare variable because it is dynamically typed. So we can write a=100 to assign an integer value in an integer variable.

Python makes the development and debugging fast because there is no compilation step included in the python language development and the edit test debug cycle is very fast.

Python 2 vs Python 3

Python programming language is the most powerful language. whenever a new version is released, it supports the features and syntax of the existing version of the language.

Therefore, it is easier for the projects to switch to the newer version. However, in the case of python, the two versions Python 2 and Python 3 are very much different from each other.

A list of differences between Python 2 and Python 3 is given below.

1. Python 2 uses print as a statement and used as a print ("Somethings") to print some string on the console.

Python 3 uses print as a function and is used as a print("Somethings") on the console.

2. Python 2 uses the function raw_input() to accept the user's input. It returns the string representing the value, which is then typed by the user. To convert int into the integer we need to use the int() function in python.

Python 3 uses the input() function which automatically interpreted the type of input entered by the user.

However, we can cast this value to any type by using primitive function int(), str(), etc.

3. Python 2 the implicit string type is ASCll.

Python 3 the implicit string type is Unicode.

4. Python 3 does not contain the xrange() function of python 2. The xrange() is the variant of range() function. which returns an xrange object that works similar to a java iterator. The range() returns a list.

5. There is also a small change made in exception handling in python 3. It defines a keyword as which is necessary to use. we will discuss it in the exception handling section of the python programming course.
