Hello World in Python
print("Hello World!")
Python was created by Guido van Rossum.
The first version of Python as released in the year 1991.
Python's design philosophy encourages code readability.
Python creates code blocks via indentation as opposed to using curly braces like other Programming languages.
Python is both Functional and Object Oriented Programming language. You can run a Python program without creating a class.
It was designed with a focus on readability and ease of use, making it a popular choice for both beginner and advanced programmers. Python's design philosophy emphasizes code readability, and its syntax allows programmers to express concepts in fewer lines of code than languages like C++ or Java.
Python has a large and active community of developers who have created a vast ecosystem of libraries, tools, and frameworks for various applications such as web development, data science, machine learning, and scientific computing. Some of the popular libraries and frameworks in the Python ecosystem include NumPy, Pandas, Matplotlib, Django, Flask, TensorFlow, and PyTorch.
One of the key features of Python is its dynamic type system, which allows programmers to write more concise and expressive code. In Python, variables do not have to be declared with a specific data type, as the type of a variable is determined at runtime based on the value assigned to it.
Python is also an interpreted language, meaning that it is not compiled into machine code like languages such as C++ or Java. Instead, Python code is translated into byte code, which is executed by the Python interpreter. This makes Python programs more portable, as they can be run on any system with a Python interpreter installed.
Python supports multiple programming paradigms, including procedural, object-oriented, and functional programming. It also has a vast standard library, which provides developers with a wide range of built-in functions and modules to perform common tasks such as file I/O, networking, and regular expressions.
Python has become increasingly popular in recent years, particularly in data science and machine learning fields, due to its ease of use and powerful libraries for data analysis and visualization. It has been used by companies such as Google, Facebook, and Dropbox to build large-scale applications.
Overall, Python is a versatile and powerful programming language with a wide range of applications. Its ease of use and large community of developers make it an excellent choice for both beginners and experienced programmers alike.
Python programs can be developed via an IDE like Eclipse IDE or IntelliJ PyCharms or text editors like Atom, VS Code etc.
However for beginners it is recommended to start programming via a text editor or IDLE so that you can get a firm grasp of the concepts of the language.
We have started this training module with a hello world program as displayed above.
You can use the left hand navigation to jump directly to a Python module you are interested in.
Alternative you can use previous and next links in a given module to go step by step. Happy learning!
