Help!

Maybe you already know the name of a Python function, but you still have to figure out how to use it. Ironically, you have to ask for information about a function with another function: help(). In IPython specifically, you can also use ? before the function name.

To get help on the max() function, for example, you can use one of these calls:

help(max)
?max

Use the IPython Shell to open up the documentation on pow(). Do this by typing ?pow or help(pow) and hitting Enter.

Which of the following statements is true?

Possible answers

pow() takes three arguments: base, exp, and mod. Without mod, the function will return an error.

pow() takes three required arguments: base, exp, and None.

pow() requires base and exp arguments; mod is optional.

pow() takes two arguments: exp and mod. Missing exp results in an error.
