Creating Functions with Parameters
Lesson Objectives
• Write functions with parameters to generalize a
solution instead of duplicating code.
• Identify appropriate situations for creating a
function with parameters.
• Use random numbers as inputs to function calls for
the purpose of testing.
• Add parameters to a function in an existing piece of
code to generalize its behavior.
Creating Functions with Parameters
Think-Pair-Share
What is the benefit of using parameters in a function?
• Makes your function more responsive to different
scenarios
• Your function is a general solution to many
problems
