Your Learning in This Python Course Online!

The concept of Python course was first introduced in the late 1980s by Guido van Rossum, member of the National Research Institute of Mathematics and Computer Science.

Initially, it was formulated as a response to ABC programming language which was founded in the Netherlands.

Van Rossum was working as an implementer at the CWI (Centrum Voor Wiskunde en Informatica) for ABC programming language when he started developing a new scripting language which resembled the structure of the ABC language, but was accessible to the AMOEBA system calls; a distribution system that he was working on at the time.

So he began to develop a new language of programming that would overcome the flaws of the ABC language. His efforts paid off in the year 1991 when he introduced the first/initial version of the language which he named as Modula 3.

If you remember then way back during the 1970s, there was a popular comedy show which was telecasted on BBC comedy TV, the name of the show was Monty Python’s Fly Circus. So Van Rossum being a huge fan of the show named his project as “Python”. This is how Python came into existence.

Python is a high-level performing general-purpose language which is object-oriented. It caters a wide range of applications like Web development (Django and Bottle), app development, scientific and mathematical computing (Orange, SymPy, NumPy) and desktop graphical user Interfaces (Pygame, Panda3D).

The structure of the language is very easy and clean and its length of the code is short as compared to others. Working with Python offers you a larger problem-solving approach as it is simple to comprehend and understand.

Python offers built-in data structures along with fast typing and binding which makes it an effective language for Rapid Application Development.

Along with this, the programming language not only supports packages and modules but also encourages code reuse and program modularity.

It also eliminates the compilation step which in turn increases productivity and decreases the overall cost of the program.

Why Python Certification from KnowledgeHut?   

python-online-course

Python stands tall on the seventh rank in the category of the most popular programming language of the world among software developers. And according to a developer survey by Stackoverflow in the year 2018 it has been chosen as the most wanted technology of the year.

Before you start learning the language, make the right choice. There are a lot of learning resources available in the market today that teach you coding in the third version without any prior experience in Python version 2.  The third version Python 3 is the latest version and also the future. So if you decide to start learning the language with the latest version it is going to be great for you.

WHAT WILL YOU LEARN IN THIS COURSE?                                      

Python Certification is best offered by KnowledgeHut where the course comprises of instructor-led 24 hours live session along with 7- hours of Multiple Choice Questions and assignments. Not just the training it also provides you with 22 hours of hands-on practical sessions and three use cases.

The Python certification training from KnowledgeHut introduces the learner to a new world and helps you learn the language from scratch. It also provides exposure to architecture, design philosophy, basics of scripts, applications, and packages through hands-on practical sessions.

Before you begin with the course it is important to know what are you going to learn in the course.

  1. Install Python

The first step is to install Python so begin your Python journey by learning to Install Anaconda – Python /*distribution.

The topics covered in this course are:

  • Python Editors and IDEs
  • Install Anaconda
  • Hands-on:
  • Install Anaconda – Python distribution
  1. Master Python fundamentals

You can easily create your first program on Python by learning its basic structure, the variables, its types, and so on…

  1. Data Structures

It is important to know the data structures that Python handles. Here you will learn to create, manipulate Python lists, tuples, etc.

Learning Objective:

To learn the various data structures that are used in Python.

The topics which will be covered in the course are:

  • Arrays
  • Lists
  • Tuples
  • Dictionaries
  • Sets
  • Hands-on: here you can write the Python Code to understand and implement Python Data Structures.
  1. Conditional Statements

This is where you learn how to write the codes for complex decision making. This can be achieved by mastering control structures like if, for, while, break and a few more.

  1. Modules

Here you will learn to write and import your Python modules and their usage in other directories

Learning Objective:

The objective is to learn building modules and installing packages.

  • Hands-on:
  • Write Python Code to create modules and execute them.
  1. Regular Expressions

This will teach you about Regular Expressions; what is their use in parsing files, text for information and matching patterns.

Learning Objective:

The objective is to learn about Regular Expression Objects, subexpressions, tips, and tricks that one implements while coding.

The topics which will be covered in this course are:

  • Pattern matching
  • Parsing data
  • Subexpressions
  • Complex substitutions
  • RE tips and tricks
  • Hands-on: Writing codes to use Regular Expression, matching pattern, parsing data and so on.
  1. Object-Oriented Programming

The objective is to learn how to do object-oriented programming and writing user-defined functions.

Learning Objective:

The objective is to gain knowledge on OOPs to code easily and efficiently. And to learn how to construct classes and define objects.

The topics which will be covered in this course are:

  • Introduction to Python Classes
  • Defining Classes
  • Initializers
  • Instance Methods
  • Properties
  • Class Methods and Data
  • Static Methods
  • Private Methods and Inheritance
  • Module Aliases
  • Hands-on: Writing codes to construct a class and to define objects.
  1. Master Python best practices

You can now take your Python programming skills to the next level with functions, import packages, and improved code readability

 

HOW IS KNOWLEDGEHUT DIFFERENT?

INSTRUCTOR-LED LIVE CLASSROOM

The course offers you real-time interaction with the instructors that are experts from the industry. You can listen, learn, and ask questions simultaneously.
