In-place assignment operators (also called compound assignment operators) perform an operation in-place on a variable provided as first operand. They overwrite the value of the first operand variable with the result of the operation when performing the operator without assignment. For example, x += 3 is the same as x = x + 3 of …

Python’s in-place bitwise left-shift operator x <<= y calculates the left-shift operation x << y, and assigns the result to the first operands variable name x. You can set up the in-place left-shift behavior in your own class by overriding the magic “dunder” method __ilshift__(self, other) in your class definition. The expression x <<= y …
This tutorial is about training deep learning (DL) models to classify Star Wars Lego images. We use the TensorFlow library to create and compare the image classifiers. Are you looking for interesting deep learning projects that are suitable for beginners? Do not worry, this is not another MNIST image classification tutorial. Instead, we are going …

Python’s in-place bitwise XOR operator x ^= y calcualtes bitwise XOR x ^ y and assigns the result to the first operand x. To set this up for your own class, override the magic “dunder” method __ixor__(self, other) in your class definition. The expression x ^= y is syntactical sugar for the longer-form x = …
Introduction Have you ever come across strings in Python that have unnecessary spacing between the words or characters? If so then you are at the correct place to find the solutions to your problem. In this article, we are going to learn about the different methods to remove multiple spaces in a string. In Python, …

This machine learning cheat sheet gives you a visual overview of 6 must-know machine learning algorithms (and where to learn more). Linear Regression: train your linear model to predict output values. K-Means Clustering: apply it on unlabeled data to find clusters and patterns in your data. K-Nearest Neighbors: use a similarity metric to find the …

Logistic regression is a popular algorithm for classification problems (despite its name indicating that it is a “regression” algorithm). It belongs to one of the most important algorithms in the machine learning space. Linear Regression Background Let’s review linear regression. Given the training data, we compute a line that fits this training data so that …
In this article, we will learn numerous ways to execute system commands in Python. ➥ Problem: Given an external command that can run on your operating system, how to call the command using a Python script? ➥ Example: Say you want to ping a remote server using your operating system’s ping command—all from within your Python program. How …
Python’s in-place bitwise right-shift operator x >>= y calculates the right-shift operation x >> y, and assigns the result to the first operands variable name x. You can set up the in-place right-shift behavior in your own class by overriding the magic “dunder” method __irshift__(self, other) in your class definition. The expression x >>= y …
Python’s in-place bitwise AND operator x &= y calcualtes bitwise-and x & y and assigns the result to the first operand x. To set it up for your own class, override the magic “dunder” method __iand__(self, other) in your class definition. The expression x &= y is syntactical sugar for the longer-form x = x …
Python provides the in-place exponentiation operator x **= y that raises x to the power of y using x ** y and assigns the result to the first operands variable name x. You can set up the in-place exponentiation behavior for your own class by overriding the magic “dunder” method __ipow__(self, other) in your class …
