Sorting is a basic building block that many other algorithms are built upon. It’s related to several exciting ideas that you’ll see throughout your programming career. Understanding how sorting algorithms in Python work behind the scenes is a fundamental step toward implementing correct and efficient algorithms that solve real-world problems. In this course, you’ll learn: How different sorting algorithms in Python work and how they compare under different circumstances How Python’s built-in sort functionality works behind the scenes How different […]

The built-in Python function eval() is used to evaluate Python expressions. You can pass a string containing Python, or a pre-compiled object into eval() and it will run the code and return the result. Although Python’s eval() is an incredibly useful tool, the function has some important security implications that you should consider before using it. In this course, you’ll learn how eval() works and how to use it safely and effectively in your Python programs. In this tutorial, you’ll […]

Whether you’re just getting to know a dataset or preparing to publish your findings, visualization is an essential tool. Python’s popular data analysis library, pandas, provides several different options for visualizing your data with .plot(). Even if you’re at the beginning of your pandas journey, you’ll soon be creating basic plots that will yield valuable insights into your data. In this course, you’ll learn: What the different types of pandas plots are and when to use them How to get […]

Python supports a wide range of arithmetic operators that you can use when working with numbers in your code. One of these operators is the modulo operator (%), which returns the remainder of dividing two numbers. Modular operations are useful to check if a number is even or odd, simplifying cycling through data, and doing non-decimal based units conversion. In this course, you’ll learn: How modulo works in mathematics How to use the Python modulo operator with different numeric types […]
