You likely don’t need to know about this in your first week of using Python, but as you dive deeper into Python you’ll find that it can be quite convenient to understand how to pass a function into another function. This is part 1 of what I expect to be a series on the various ...
Arbitrary arguments allow us to pass a varying number of values during a function call. We use an asterisk (*) before the parameter name to denote this kind of argument. For example, # program to find sum of multiple numbersdeffind_sum(*numbers):result =0fornuminnumbers: result = result...
Since our decorator takes a function as an argument, we’ll define a new function and pass it to the decorator. We learned earlier that we could assign a function to a variable. We'll use that trick to call our decorator function. def say_hi(): return 'hello there' decorate = upper...
