Python: Check if Variable is a String

Introduction Python is a dynamically typed language, and the variable data types are inferred without explicit intervention by the developer. If we had code that requires a string to work correctly but lacked type hints, which are optional, how can we avoid errors if the variable used is not a string? In this tutorial, we’ll take a look at how to check if a variable is a string in Python, using the type() and isinstance() functions, as well as the […]

Seaborn Line Plot – Tutorial and Examples

Introduction Seaborn is one of the most widely used data visualization libraries in Python, as an extension to Matplotlib. It offers a simple, intuitive, yet highly customizable API for data visualization. In this tutorial, we’ll take a look at how to plot a Line Plot in Seaborn – one of the most basic types of plots. Line Plots display numerical values on one axis, and categorical values on the other. They can typically be used in much the same way […]

Navigating Namespaces and Scope in Python

In a program of any complexity, you’ll create hundreds or thousands of names, each pointing to a specific object. How does Python keep track of all these names so that they don’t interfere with one another? This course covers Python namespaces, the structures used to organize the symbolic names assigned to objects in a Python program. In this course, you’ll learn: How Python organizes symbolic names and objects in namespaces When Python creates a new namespace How namespaces are implemented […]

Differential Evolution Global Optimization With Python

Differential Evolution is a global optimization algorithm. It is a type of evolutionary algorithm and is related to other evolutionary algorithms such as the genetic algorithm. Unlike the genetic algorithm, it was specifically designed to operate upon vectors of real-valued numbers instead of bitstrings. Also unlike the genetic algorithm it uses vector operations like vector subtraction and addition to navigate the search space instead of genetics-inspired transforms. In this tutorial, you will discover the Differential Evolution global optimization algorithm. After […]

Serializing Objects With the Python pickle Module

As a developer, you may sometimes need to send complex object hierarchies over a network or save the internal state of your objects to a disk or database for later use. To accomplish this, you can use a process called serialization, which is fully supported by the standard library thanks to the Python pickle module. In this course, you’ll learn: What it means to serialize and deserialize an object Which modules you can use to serialize objects in Python Which […]
