ImportErrors are one of the most common python exceptions. Import errors are caused when a particular module is inaccessible or cannot be found. This error is also raised when modules are in circular dependencies. Syntax errors and version mismatches can…
In python, it is possible to import one module or class from inside another. A circular dependency is created when one module is imported from another(directly or indirectly). Circular dependencies cause recursion, leading to infinite looping, failures, tight coupling, and…
Einstein summation is used to simplify tensors, matrices, and vector expressions. It is a notational convention. In python, numpy provides a function named, einsum() that can compute the Einstein summation either implicitly or explicitly, as specified. Numpy in the implicit…
For loops are used mainly to iterate over a collection of integer or character literals in python. It is useful when we have a list of items, and we have to go through them one by one. For loops are…

Strings are a collection of characters. It is an immutable data type. Since python doesn’t have a character datatype specifically, it converts the elements of a string into its’ respective Unicode characters. Syntactically, strings are declared in between double or…
One of the most useful features of Python is its huge collection of in-built modules. Modules make everything easier. Due to the availability of numerous python libraries, implementing python code using the in-built modules has increasingly become hassle-free. But, when…
Python lists can be nested in the form of 2d structures as a replacement for arrays in other languages. Since python doesn’t have an array data type, it uses lists to create these 2d, 3d or sometimes N-dimensional arrays. Flattening…
When we extract information from data, we come across identical values very often. There are ways in which we can eliminate the duplicates to create a unique array. Or we can also determine which elements have a copy and create…
Buttons are an important part of messaging nowadays. In discord, the button feature of in a message was added recently to make some tasks like playing or pausing music easier. When adding bots, using the discord developer’s portal and python,…
