Introduction to Python
Python is one of the most popular dynamic programming languages, along with Perl, Tcl, PHP, and Ruby. Although it is often viewed as a scripting language, it is a general purpose programming language along the lines of Lisp or Smalltalk.
Today, from throw-away scripts to large scalable web servers that provide uninterrupted service 24×7, Python is used for everything. It is used for GUI and database programming, client and server side web programming, and application testing. It is used by scientists writing applications for the world’s fastest super computers and also by children who are learning to program for the first time.
Python is a direct product of Guido Van Rossum’s experience at CWI (Centrum Wiskunde & Informatica). Being a fresher at CWI, very little did he know that his experience would lead him to create something exceptional that Python programmers idolize today.
Python’s early development started at a research institute in Amsterdam, which is a Dutch acronym for a phrase that translates into English as Center for Mathematics and Computer Science. CWI is an interesting place; funded by the Dutch government’s Department of Education and other research grants. It conducts academic-level research into computer science and mathematics.
Rossum’s motivation for creating Python was the need for a higher-level language in the Amoeba project. The development of system administration utilities in C was taking too long. Moreover, doing these in the Bourne shell wasn’t working for a variety of reasons. The most important one was that as a distributed micro-kernel system with a new design, Amoeba’s primitive operations were very different than the traditional primitive operations available in the Bourne shell. So there was a need for a language that would “bridge the gap between C and the shell.” For a long time, this was Python’s main catchphrase.
Then the next issue popped up, why the name Python? The name finally emerged in his mind after the thought of Monty Python Flying circus. The word “Python” was also catchy, a bit edgy, and at the same time, it fit in the tradition of naming languages after famous people, like Pascal, Ada, and Eiffel. The Monty Python team may not be famous for their advancement of science or technology, but they are certainly a geek favorite.
Python was finally released on February 20th, 1991 under the version labeled 0.9.0. Since then, the invention has been buzzing all over the news and the rest is history.
Why Choose Python?
Whether it’s easy to learn or quick coding, python gives you some pretty good reasons to adopt it. Experience programming with the best!

An Integrated Development Environment is one of the best tools a programmer could use. It enables developers to work efficiently. While some programmers discredit the idea of using more than a text editor, when you find yourself working for a big project, an IDE will have features that makes the life of a developer quite easy.
A brief on Introduction to Python IDE will help you unveil the advantages of using it.
What are Strings?
Strings are the most important data types in computer languages. A string in python is a sequence of characters and are immutable. This means that once defined, they cannot be changed. For example, the replace
They do not modify the original string. They create a copy of a string, which they modify and return to the caller.
Python For Big Data Jobs
If you’re out there looking for a big data job, then you might have to look into python which is a must to be in your resume. A combination of python and big data can help you qualify for the job.
To know why, take a look at Why Python training is essential for big data jobs.
Python for Data Science
Data scientists today, are in need of python to carry out their tasks smoothly. The use of python to Java is comparatively easier for most data scientists, since Java is too complex.
Python can’t get better! Take a peek at Python for Data Science.
Sounds absurd? Or rather like a tongue twister? Matplotlib is an excellent 2D and 3D graphics library for generating scientific figures. It is quite easy to get started with and has a great control of every element in a figure, including figure size and DPI.
Importance Of Python Tutorial
For budding professionals in the programming world, getting some hands-on experience and understanding the python tutorials could speed up their career with a good python job. Hence, the tutorial is a must.
Hello World Program
In case you’ve started with understanding python and attempting to learn how to write it, then Hello World Program might help you. It gives an insight to a programmer about python covering the basics of how you can get started with Python.
Command Line Argument
A command line argument is nothing but an argument sent to a program. A program can take any number of command line arguments. For example, type the following command:
cat is the name of an actual command and shell executed this command when you type command at shell prompt. The first word on the command line is:
- cat – name of the command to be executed.
- Everything else on command line is taken as arguments to this command.
- Total number of command line arguments passed to the ls command, including command name itself are 2.
In any programming, exceptions and error handling often becomes a necessity when dealing with a lot of variables. The goal is to execute the code as intended. Let’s take a look at exceptions and understand why is it used.
