First Learn Python to Start Your IT Career
First Learn Python to Start Your IT Career…
If you are new to Programming then first learn Python, or already know some programming, or testing, or networking or some other technology in the IT Industry, then also learn Python, It improves your career.
Old suggestion in the IT industry is “First Learn C language” then you can easily learn other Software technologies, but latest suggestion is “First learn Python Language” then you can smoothly move in the IT Industry.
What is Python?
Python is a general-purpose interpreted, interactive, object-oriented, high-level, open source programming language. It was created by Guido Van Rossum in 1989, but publicly released in 1991.
Python and all the necessary tools are available on all major platforms.
Basic understanding of Computer Programming terminology and of any of the programming languages is a plus.
How is Python Used?
Python can be used for nearly everything.
Majority of web applications and platforms rely on Python, including Google’s search engine, YouTube, and the web-oriented transaction system of the New York Stock Exchange (NYSE).
Python can also be used to process text, display numbers or images, solve scientific equations, and save data.
Easy-to-learn – Python has few keywords, simple structure, and a clearly defined syntax. This allows a Person to pick up the language quickly.
Easy-to-read – Python’s source code is fairly easy-to-read and understand
Easy-to-maintain – Python’s source code is fairly easy-to-maintain.
A broad standard library – Python’s bulk of the library is very portable and cross-platform compatible on UNIX, Windows, and Macintosh.
Interactive Mode – Python has support for an interactive mode which allows interactive testing and debugging of snippets of code.
Portable – Python can run on a wide variety of hardware platforms and has the same interface on all platforms.
Databases – Python provides interfaces to all major commercial databases.
Scalable – Python provides a better structure and support for large programs than shell scripting.
Distribution of Python
CPython is the reference implementation of Python written in the C programming language.
Jython is an implementation of the Python programming language that can run on the Java platform. Jython programs use Java classes instead of Python modules .Jython compiles into Java byte code, which can then be run by Java virtual machine.
A Python implementation written in C# targeting Microsoft’s .NET framework. Similar to Jython, it uses .Net Virtual Machine i.e Common Language Runtime. IronPython can use the .NET Framework and Python libraries, and other .NET languages can use Python code very efficiently.
Anaconda is a free and open-source distribution of the Python and R programming languages for scientific computing (data science, machine learning applications and large-scale data processing)
Python Applications / Uses of Python:
i. Desktop GUI
ii. Web and Internet Development
iii. Games and 3D Graphics
iv. Scientific and Numeric Applications
v. Machine Learning and Artificial Intelligence
vi. Data Science
vii. Business Applications (Such as e-commerce, ERP and many more.)
viii. Network Programming
ix. Embedded Applications
x. Audio and Video Applications
xii. Software Testing / Writing automated tests
xiii. Python for DevOps / System administration / Writing automation scripts.
(The ultimate goal with DevOps is to automate each task in the development life cycle to save time. With python modules and libraries we can do automation using the tools and scripts written in python.)
Note: Python can be used with Selenium, and Appium for Automated Testing.
Practice Python Programming:
(We can download Python Software from the official website python.org, Python supports various operating systems, download your operating system compatible Python software.)
> Download & Install Python
> Set path while Installation
> Launch Python IDLE (Integrated Development & Learning Environment)
> Write Python Code using Interactive Mode or Script Mode, and Execute.
Note: You can download PyCharm IDE, Install it, set python executable in PyCharm, and use PyCharm IDE to write & execute Python programs. Python IDLE is best for learning purpose, and PyCharm IDE for realtime.
If you want to use Eclipse IDE for Python then you need install pydev plugin for Eclipse IDE.
First Focus on Python Fundamentals:
> Python Basic Syntax
> Python Variables
> Python Data Types
> Python Operators
> Python Control Flow (Conditions, Loops, and Branching)
> Python User Input
> Python Functions (Built-in & User defined)
> Python Object oriented Programming (Class, Object, Method, Inheritance, Polymorphism, Abstraction, and Encapsulation)
