Introduction of python programming language:

 Python programming language

What is python?

• Python is a powerful high level, object oriented, interpreted language.
• Proposed by Guido van Rossum in 1989.
• It has simple, easy to use syntax and making it the perfect language for someone trying to learn computer programming for the first time.

Wherefrom the python has derived?

• In the 1980s, Guido van Rossum was working on the Amoeba distributed OS (ADOS).
• He has used ABC language (i.e., interpreted language). This is simple easy to understand syntax in ADOS.
• So, he decided to create a language that was extensible (fast).
• This is lead to the design new language which was later named “Python”.

Why the name python came?

• Guido van Rossum was a fan of a comedy serial from the late seventies.
• So, the name python was adopted from the same series “Monty Python’s Flying Circus.

Features of python language:

• A simple language that is easier to learn.
• Free and open source
• Extensible
• Large standard library to solve common task.
• Object-oriented.  

Applications of python:

• Web application (Flash, Pyramid, crome, etc)
• Scientific and numerical computing (earthpy for earth science, astropy for astronomy, and so on).
• Data analytics and machine learning.

Software companies that use python:

• Google
• Quora
• Netflix
• Facebook
• Instagram
• Dropbox etc

Reasons to choose python language:

• Python interpreter act as a calculator because python has modes.

1.Shell mode (Python 3.5(32-bit):

• Shell mode immediately returns the result of the command for you to enter in the shell.

2.Script mode (IDLE(Python 3.5 32-bit):

• The script mode is used to write the script then run and also possible to immediately ran output.
• It contains edit options and you can be also, save that py document.

Working with script mode:

Numbers:

String:

• A string is a collection of characters or alphabetic and form a sentence or word called a string.
• The strings are represented by single or double quotes (“word or sentence“ or
• ’word or sentence‘).

Note:

Compiler:

• It is used to merge all programs into machine code and checking errors.

Interpreter:

• It is used to check error line by line and change it line by line machine codes.
