Introduction to Functions
Explore Python functions by learning how to define, call, and reuse them. Understand the difference between built-in and user-defined functions, function naming conventions, and how to pass arguments and return values effectively.
What are functions?
We divide a problem into subproblems and resolve a specific subproblem or task using a function. A Python function is a block of code that performs a specific and well-defined task.
Advantages of functions
Two main advantages of functions are:
- They help us divide our program into multiple tasks. For each task, we can define a function. This makes the code modular.
- Functions provide a reuse mechanism. The same function can be called any number of times.
