The NumPy where() function is a powerful tool for filtering array elements in lists, tuples, and NumPy arrays. It works by using a conditional predicate, similar to the logic used in the WHERE or HAVING clauses in SQL queries. It’s okay if you’re not familiar with SQL—you don’t need to know it to follow along with this tutorial. You would typically use np.where() when you have an array and need to analyze its elements differently depending on their values. For […]

One of the most common tasks that a computer program performs is to display data. The program often displays this information to the program’s user. However, a program also needs to show information to the programmer developing and maintaining it. The information a programmer needs about an object differs from how the program should display the same object for the user, and that’s where .__repr__() vs .__str__() comes in. A Python object has several special methods that provide specific behavior. […]

As the autumn leaves start to fall, signaling the transition to cooler weather, the Python community has warmed up to a series of noteworthy developments.
