A Newbie Guide to Python

Python is a useful programming language for writing simple and fast scripts, but it is also a good

language to use when creating large-scale applications. Even massive operations like YouTube

use Python to deliver their content on the web. Python is easy to learn for beginners while being

sophisticated enough for experienced engineers to use. Let's take a look at the features and

history of Python and explore the reasons for using it.

What is a Python?

Python is a high-level object-oriented programming language. This is an interpreted language,

which means that you do not need to compile your programs before running them, which

speeds up the code writing and debugging cycle. Python is a versatile and widely used

language, so many standard Python packages are available to you when you write your code,

rather than having to write all the algorithms from scratch.

A Brief History about Python

Python was created in the late 1980s by Guido van Rossum. Van Rossum had already worked

on a language called ABC, which was the predecessor of Python. Building on his earlier work

with ABC, van Rossum created a simple parser and virtual machine, and then began to develop

the basic syntax of Python. He named the new language after Monty Python's Flying Circus, a

popular British comedy comedy he enjoyed.

Guido van Rossum published the first version of Python in 1991. He continued to be the main

author of the language for many years, although other people also contributed to the

development of the language.

python 2 0 was released in october 2000 with

Python 2.0 was released in October 2000, with several significant improvements, including

support for Unicode and a complete garbage collector to get rid of variables that are no longer

used by the program. The latest major release of Python is Python 3.0, which includes many

simplifications over Python 2.0 and is designed to help programmers do things in the simplest

and most obvious way.

How Python is Different from Other Languages?

Python can be considered similar to other interpreted programming languages, such as

Javascript and Perl. Some programmers have also made comparisons between Python and

compiled languages, such as C ++ and Java. However, there are some key differences that

distinguish Python from its competitors.

Python vs Java/C++

Python is considered easier to use than Java and C ++, which are also object-oriented

programming languages. Python uses dynamic typing, which means programmers do not have

to spend time defining variables before using them. As a result, Python code is typically 3-5

times shorter than Java code that serves the same purpose. The comparison with C ++ is even

more favorable; Python code can be up to 10 times shorter than equivalent code in C ++.

Python vs Perl

Python is often used as an alternative to Perl, which is another scripting language that allows

programmers to quickly write useful code. However, Python is designed to be much easier to

read than Perl, allowing programmers to share, debug, and maintain code efficiently. On the

other hand, Perl has many useful features for application-oriented tasks, such as built-in regular

expressions.

Benefits of Python

Python is often considered one of the best languages to introduce beginners to programming. In

fact, 80% of the top IT departments teach Python in their introductory programming courses. It

is widely considered to have one of the most superficial learning curves of any programming

language, making it an excellent choice for new programmers.

Readable

Python is written to be read. It has a simple syntax that closely mimics English. It also uses

white spaces rather than braces to identify function bodies, forcing new programmers to have

their code in a standardized and easy-to-read way.

Concise

The Python code is very brief compared to other languages. You do not need to set variables at

the beginning of the program file because the interpreter handles input when you run the

program. It's one less thing for new programmers to think when they learn to code for the first

time.

Wide Range of Packages

In addition to being an excellent language for beginners, Python is also very useful for

experienced programmers. This is the fifth most used language on GitHub. The popularity of

Python means that many people develop packages for the language. Python.org maintains a list

of the most popular Python modules, packages, and libraries that can help programmers

visualize data, manipulate images, and develop interactive websites.

PIP

PIP stands for Python Package Index. It is a tool that you can use to quickly and easily install

Python packages. Just use the 'pip install' and 'pip uninstall' commands to add and remove

packages. PIP downloads packages before installing them, thus preventing partially completed

installations.

Interpreted

Python is an interpreted language. There is no compile step between writing the code and

executing it. This speeds up the process of writing, testing and correcting code, which is a nice

feature for many developers.

Free

Finally, Python is completely free, which gives it an advantage over a few competitors. For

example, scientists can use Python as an alternative to proprietary languages like Matlab for

data analysis and simulations.

Disadvantages of Python

Python has some disadvantages, which may make it unsuitable for certain applications.

Speed

Python works slower than many other languages. This is because it is an interpreted language.

In compiled languages, the compiler can create code that runs quickly and efficiently. As a

result, Python is slower than compiled languages, such as C or C++. There are variants of

Python, specially designed to handle certain situations, that can run faster.

python 2 vs python 3 newcomers to python must

Python 2 vs Python 3

Newcomers to Python must choose if they want to program in Python 2.7 or Python 3. Although

Python 3 is the most up-to-date version of the language, some programmers are reluctant to

make the change because many useful libraries are not yet available. Python 3. Although the

availability of two stable versions of Python is not necessarily a significant disadvantage, many

new programmers are confused by the choice. Python 2 and 3 have a similar syntax, but they

are not fully compatible, so you should be aware that two versions exist and check that all the

packages you want to use are available for your chosen version before starting your coding

project.
