[Tutor] Problem with default arguments for function

Dick, Another typical strategy is to use some prescribed special value for the precision parameter to designate the desire for full precision. For example, since precisions should presumably be positive, one could design this function as: def fact(n, precision=15): """compute n!. preci

[Tutor] Problem with default arguments for function

I just discovered mpmath () and am trying to write a useful function that uses it to compute factorials. Here's what I have: def fact(n, precision=15, full=False): """ compute n! """ from mpmath import mpf if not isins
