Whenever you think of Python’s asterisk operator (*), you most likely think of multiplication or exponentiation. Similarly, you probably associate the forward slash operator (/) with division. But you can also use the bare asterisk and slash as special parameters in function headers. These do something completely unrelated to mathematics. When defining functions, you’ll often include a list of comma-separated parameters to define what types of arguments the user can pass to your function. Using the asterisk and forward slash […]
