Python Functions Quiz

Functions in Python

• Intended learning outcomes for week 5 include defining and calling functions, creating custom object types with classes, and understanding references and mutable vs immutable objects.

• Functions are blocks of code that can be reused by calling them.

• Function calls are necessary to execute the code inside a function.

• Inputs to a function are called arguments and can be literals, variables, or complex expressions separated by commas.

• Functions can cause an effect, such as displaying output, or compute and return a result.

• Python has built-in functions that can be imported and used.

• User-defined functions can be created with parameters and a return value.

• Control flow in a function starts with the first statement and ends with the return statement or the end of the function.

• DRY (don't repeat yourself) code is a good practice that avoids code duplication and can be achieved with functions.

• Function parameters are placeholders for arguments and can have default values.

• Named arguments can be used instead of positional arguments and must come after them.

• Return statements are used to return a value from a function and terminate its execution, and can be used without a value to terminate the function.Introduction to Functions in Python

• Functions are a way to organize code for reuse and to avoid repetition.

• Functions are defined using the "def" keyword, followed by the function name and parentheses.

• The parentheses can include parameters, which are values that the function can use to perform its task.

• Functions can have a return statement, which specifies the value that the function should return when it is called.

• Functions can be called multiple times with different arguments, allowing for code reuse and flexibility.

• The scope of a variable determines where it can be accessed within a program.

• Functions can access variables defined outside of their own scope, but cannot modify them without using the "global" keyword.

• The "docstring" is a way to document a function's purpose and usage, and can be accessed using the "help" function.

• Functions can be nested within other functions, allowing for more complex code organization and reuse.

• Functions can also be imported from external modules or packages for even greater code reuse.

• Creating our own functions can improve code readability and maintainability.

• In the next lecture, we will learn about objects as another way to organize and manipulate code.
