Syntax object.__ror__(self, other) The Python __ror__() method implements the reverse Bitwise OR | operation with reflected, swapped operands. So, when you call x | y, Python attempts to call x.__or__(y). If the method is not implemented, Python attempts to call __ror__ on the right operand and if this isn’t implemented either, it raises a TypeError. … Read more
In Solidity, you can use the require, revert, and assert functions to check error conditions and handle exceptions, but they look similar at first glance, and you might get confused about how to use them. This article will explain their differences, specifically to Python developers. We use a simple smart contract below, taken from the … Read more
What is a Graph? When we want to illustrate how one thing relates to another, most often, we would preferably use a graph. From a concrete perspective, a graph is a graphical representation or an image of relationships. A graph is built of entities and their relationships. Entities represent actors in a relationship you are … Read more

This tutorial is about applying object segmentation in five lines of code. We show a beginner-friendly code implementation using the PixelLib library on Google Colab. Does machine learning have to be hard? Well, back then when everything must be coded from scratch, yes. But today, we are stepping on the shoulders of giants. Lots of … Read more
Syntax object.__rmatmul__(self, other) The Python __rmatmul__() method implements the reverse matrix multiplication @ operation with reflected, swapped operands. So, when you call x @ y, Python attempts to call x.__matmul__(y). If the method is not implemented, Python attempts to call __rmatmul__ on the right operand and if this isn’t implemented either, it raises a TypeError. … Read more
Syntax object.__rand__(self, other) The Python __rand__() method implements the reverse Bitwise AND * operation with reflected, swapped operands. So, when you call x * y, Python attempts to call x.__and__(y). If the method is not implemented, Python attempts to call __rand__ on the right operand and if this isn’t implemented either, it raises a TypeError. … Read more
Syntax object.__rmul__(self, other) The Python __rmul__() method implements the reverse multiplication operation that is multiplication with reflected, swapped operands. So, when you call x * y, Python attempts to call x.__mul__(y). Only if the method is not implemented on the left operand, Python attempts to call __rmul__ on the right operand and if this isn’t … Read more
Syntax object.__rsub__(self, other) The Python __rsub__() method implements the reverse subtraction operation that is subtraction with reflected, swapped operands. So, when you call x – y, Python attempts to call x.__sub__(y). Only if the method is not implemented on the left operand, Python attempts to call __rsub__ on the right operand and if this isn’t … Read more
