PyTorch is an open source machine learning library used for developing and training neural network based deep learning models. It is primarily developed by Facebook's AI research group. Pytorch uses core Python concepts like classes, structures and conditional loops - that are a lot familiar to our eyes, hence a lot more intuitive to understand.

This blogs on Python was compiled as I was trying to learn the language. I will present it here, for someone who might want a quick introduction to the language, without digging through all the manuals.
A Regular Expression is a way to define a string pattern. Regular expression is not limited to Java. Today, most languages have regular expressions built into them. The syntax of regular expressions is quite common among all these languages. There are some minor differences that each language proposes. But, once we have a good grasp on any one, it will not require much effort to use the same knowledge elsewhere.
Everything in Java is an Object of a Class - including the classes themselves. Any class in Java is an object of java.lang.Class. It has defined its properties and methods that allow you to work on these properties. This is a very powerful feature of the Java language.
