Expand your Python programming skills

Learning how to debug is the most valuable skill to develop as you learn to program. This four-week course from the University of Michigan will help you improve your programming ability by providing you with the skills you need to understand and debug code.

What’s more, you’ll learn the crucial techniques to help minimise mistakes and problems in your code.

Use a debugger to fix problems with your code

Most modern development environments contain a debugger, which you can use to find bugs and understand what is happening in your code. However, many people still rely on print statements when they debug.

This course will help you gain confidence in using debuggers, so you can spend less time seeking out and fixing bugs and focus on building exciting new programming projects.

Learn to recognise semantic and syntax errors in your code

The majority of coding errors occur when the programmer doesn’t understand the code or makes mistakes with the language, resulting in bugs.

On this course, you’ll gain the knowledge and skills needed to spot and solve semantic and syntax errors more easily. You’ll also streamline your coding process by learning to write and run unit tests to examine and check your code.

Study with the experts at the University of Michigan

Barbara Ericson is an Assistant Professor in the School of Information at the University of Michigan and an award-winning author of computing curricula.

With her years of expertise and creative approach to programming, she is best positioned to help you unlock your programming potential by hunting and squashing bugs.

What topics will you cover?

  • Discover strategies to minimize the number of bugs (mistakes) in your code.
  • Learn how to use a code stepper to see exactly what happens when code executes.
  • Gain skills with common tasks in a debugger (setting breakpoints, examining variable values, stepping through code).
  • Learn to recognise common syntax and semantic errors.
  • Understand how to create unit tests to test your code.
  • Use the output from unit tests to debug your code.
