Understanding Python’s Complex() Function: A Beginner’s Guide to Working with Complex Numbers

Learn How to Create, Perform Calculations and Convert Strings to Complex Numbers in Python with Easy-to-Follow Examples

Complex numbers are numbers that contain both a real and an imaginary part, and they are commonly used in scientific and engineering applications. In this article, we will explore the complex() function in more detail, and provide practical examples of how it can be used in real-world scenarios. Whether you are new to Python or a seasoned developer, understanding how to work with complex numbers using the complex() function is an essential skill that will help you to build more robust and sophisticated programs. So, let’s dive in and learn more about the complex() function in Python.

The syntax for the complex() function is as follows:

complex(real, imaginary)

The real and imaginary arguments can be integers, floating-point numbers, or any expression that evaluates to a number.

Using the complex() function in Python

Let’s look at some examples of how the complex() function can be used in Python.

Creating a complex number

To create a complex number using the complex() function, we simply pass in the real and imaginary parts as arguments. For example:

x = complex(3, 4)
print(x)

Output:
