[Tutor] Question on lists
Thu, 18 Mar 1999 08:21:41 -0800
Hi - I'm trying to write a function that will return a list of prime factors
of a given number. For example, factor(36) would return [2,2,3,3]. What I
have so far is given below. Trouble is, each time it factors the quotient, a
is given as an empty list again. At this point, it's returning just the
first prime factor of the number. Is there any way to work around this?
Thanks in advance,
# Factor by trial division:
a =  # Is there a better way to define a?
k = floor(sqrt(n))
for i in range(2, k+1):
if n%i == 0:
factor(n/i) # Factor quotient
