Python Tutorial For Beginners


Python Tutorial

Welcome! to the Python tutorial.

If you are new to programming or an intermediate programmer and want to learn the new generation language Python then start now right here.

We will cover topics of python in every detail and yet very easy to understand. We believe in learning with examples so you will see lots of examples with pictures which clears your concept very easily.

We also have an FAQ at the end of each topic for you in any doubt.


What is Python?

Python is a widely used high-level programming language. It is often compared to Tcl, Perl, Scheme, or Java. However, Python is much more flexible, powerful, and readable than these other systems.

Python is so versatile that it can be used to write a simple computer program to create a complex AI algorithm.

Python is a programming language that lets you work more quickly and integrate your systems more effectively. You can use Python as your base language for your own applications, either interactively in a text editor or non-interactively as a scripting language.

Python is an interpreted language. This means that Python is read as a sequence of characters, and the interpreter does the work of translating the characters into the appropriate actions. This allows Python to be a very powerful language, but also means that Python is not a compiled language. Compiled languages are typically compiled to machine code, which is faster and more efficient than source code.

Python is a free and open-source language.

Python is multi-platform.

Python is cross-platform.

Python support multiple programming paradigms like Object Oriented, Procedure Functional, etc.

Python is the most useful programming language of the current era. It was created by Guido Van Rossum and was released in the year 1991.

Python is a dynamic programming language and has an automatic memory management system, which means it requires less rigid coding and hence is a beginner-friendly language.

The motive of python language is to let programmers and developers focus on creating logic rather than worrying about syntax memory management.

Python is very rich in its standard libraries it is also called to be "batteries included" because of this.

Python Example Codes

The python code syntax is very easy to read, write and understand.

python codes are so easy that you can understand code very much just by reading it.

To print something on the screen you just have to use the print method in python.

print("Hello World!")

Output:

Hello World!

Similarly repeating a task by creating a loop in python is also easy and readable.

for i in range(3):
    print("Python Tutorial");

Output:

Python Tutorial

Note: Don't worry if you do not understand the code we will discuss these later in detail.


What is Python used for?

Day by day python is evolving and it is being used in almost all areas of software development and the technical field. Simply you can say python is everywhere.

Python is used in almost all fields of application development such as:

python use

It is also used in the world of scientific computing, via the Python Scientific Package (PythonSci).


Why you should learn Python?

Python is extremely versatile and can be used in almost all fields. It can be called Future language. Why not learn just one language and work in multiple fields. If you want more reasons to learn python here are a few:

  1. Easy - Python is very easy to read, write and learn. It is a good choice to start learning to program.
  2. Growth - Python is the fastest-growing language. According to StackOverflow python is the fastest growing language in the world.
  3. Demand for jobs - Python is also among the highest in demand for jobs. Once you learn python you can choose one of the multiple fields Python is used in.
  4. Community - Python community is really vast and supportive. Any issue that you face has a high chance that it has been solved in the past to get a solution for your problem.
  5. Scripting and Automation - Python can be used for writing programs for small and big devices of home to automate it which makes it cool.

Python history

Python was created by Guido van Rossum in 1991 at CWI in Netherland. It was first released in 1991 and was the most popular language in the world at that time. It was created to be a free and open-source language.

The idea of python programming language was taken from ABC programming language which was created by Ada Lovelace in 1820.


Python versions

Python supports 2 major versions:

  1. Python2
  2. Python3

But python organization has announced that from Jan 1, 2020, they will not improve Python 2, they have suggested to every organization using python to switch to Python 3 as soon as possible.

We will also look at python 3 in this python tutorial.


Python Code Example

Here are some examples in python.

Printing your name in python.

print("John Smith")

Output:

John Smith

Printing the first 10 numbers.

# Printing 10 number
for i in range(0):
    print(i)

Output:

0
1
2
3
4
5
6
7
8
9
# printing numbers from 1-10
for i in range(1, 11):
    print(i)

Output:

1
2
3
4
5
6
7
8
9
10

Conclusion

Python is a highly useful yet very simple programming language. We have to see what Python is used for, what python can do, the history of python, simple code snippets. In the coming chapters, we will learn other concepts of python like variables, conditions, loops, data structure, etc.
