Give Feedback

Whether you’re looking to ace your coding interview or simply to level up your development skills, solving coding challenges can help you grow as a programmer. In this Real Python Code Conversation, Philipp challenges Martin to write a function that doubles each character in a string. Through their conversation, you’ll learn how to tackle a coding challenge and stand out from the pack in your job search.

In this video course, you’ll learn how to:

  • Use functions to write reusable, maintainable code
  • Communicate your thoughts in a coding interview
  • Use if __name__ == "__main__" to build multipurpose code
  • Write tests and use test-driven development

At the end of the course, you’ll get to hear how Martin did with the coding challenge, and you’ll leave with resources for further exploration.
