Document Summary

Section overview: in this section, the speaker introduces the concept of functions and their importance in breaking down a big project into smaller tasks. The speaker also discusses the concept of modularity. A function is defined using the keyword followed by the function name. The speaker defines a simple function called . The function takes a value from the user and assigns it to a variable called. The speaker demonstrates how to pass parameters to a function. When passing variables to a function, python uses "pass by value" rather than "pass by reference". If you modify the value of a variable inside a function, it does not affect the original variable outside of that function. There are different types of parameters that can be passed to functions. Positional arguments are passed based on their position in the argument list. Keyword arguments are passed with an explicit keyword=value syntax. Default arguments have default values specified in the function definition.
