Course Description
A function is a subset of code meant for repeated use in one or many programs. This course explores different function types and how to use pre-built functions for a variety of purposes, including mathematical operations. You’ll also learn about user-defined functions, which are functions created by the programmer, to provide more customized results for things not in the general library of functions.
What You'll Learn
- Identify the different types and purposes of functions in Python
- Use pre-built functions for mathematical operations and string handling
- Decide when to use pre-built functions versus creating your own
- Create user-defined functions to produce more customized results
- Apply functions as reusable subsets of code across one or many programs
Key Takeaways
- A function is a subset of code meant for repeated use in one or many programs.
