Extracted text: The perm(n,k=None) function of the python math library (import math) returns the number of ways to choose k items from n items without repetition and with order. Select which are true. (HINT: You expect you to do a little research on this. I do not expect you to know the answer. Consult https://docs.python.org/3/library/math.html#special-functions or help(math.trunc) ). Raises TypeError if either of the arguments are not integers. Raises ValueError if either of the arguments are negative. If k is not specified or is None, then k defaults to n and the function returns n!. Evaluates to n! / (n - k)! when k <= n="" and="" evaluates="" to="" zero="" when="" k=""> n.
