Points to ponder
Introduction to Python :
Python is Object-oriented programming language (OOPs), designed for code ease for all-purpose which other languages do not have. Variable creation and syntax are very simple to understand as compared to other object-oriented languages.
Python evolution :
Guido van Rossum trying to create an interpreter (you will come to know the difference between interpreter and compiler in later chapters) for new scripting language and named the project Python. So open interpreter in public and named Python in 1991 as a language.
The need for python :
It was needed in early 2000 when programming becomes so complex to understand and code then python was substituting with all other programmings object-oriented language with its simple syntax, unable to declare variables and other features. So then till now it is so popular used in many ways.
How python is different from other languages :
It is so different and easy from other programming languages using its syntax and class declaration.
No need to declare variables. If int x = 20 in other oops language x needs to assign either integer or character or other variable but in python no need to declare variable only x = 20 will work fine.
Speed is so fast as much liked language for Machine learning and Data Science modeling and bigger projects.
Class creation and calling in very easy as compared to other languages.
Any kind of work you may think of can be done with python which is its high positive point like data analysis, data science, big data and any kind of computer things.
Python versions :
The Python version release are as follows:
Python 3.1 - 27 Jun 2009
Python 3.2 - 20 Feb 2011
