8,569 PointsDifference between number_of_tickets and num_tickets?
Can someone quickly explain what the difference is between these two? Why is the former set as the parameter of the function calculate_price when the variable we store and pass in later on is num_tickets? It's a bit confusing...

is a program variable, number_of_tickets
is just a function parameter name that acts as a placeholder for the actual value that will be supplied when the function is used.
Parameter names can be anything, but it is considered a "best practice" to use a name that suggests what kind of contents the parameter will hold.
