From: Alan Gauld Date: 08/09/06 03:30:28 To: Kermit Rose; tutor@python.org Subject: Re: [Tutor] Exercise in writing a python function. > The current specifications for the function are: > > def incr(mult,z,zlim,mpylist): > # mult is a vector of exponents for the multipliers in mpylist. > # z is a positive odd integer. > # zlim is the upper bound critical value for the sum of ( > mpylist[k][0] * > mpylist[k][1] ) Just to clarify what this means. you have mpylist = [(2,3),(3,5),(5,7)] So the products list is: [6,15,35] So zlim in this case should be greater than the sum of products: 6+15+35 = 56 ******* Oops. That is what I said. I made a mistake in the specificiations. I should have specified that for this example that 3*mult[0] + 5 * mult[1] + 7 * mult[2] must be < zlim. >>>>> # where kth multiplier is mpylist [k][0] > # and kth multiplier index is mpylist [k][1] Not sure what you mean by the multiplier index? The sum above shows mpylist[k][1] being used in the multiplication, not as an index? ****** Yes. It's confusing because of my mistake of confusing mpylist[k][1] with mult[k]. >>>> > # function incr returns the next value of vector mult. I'm still not clear what mult does, your example above doesn't refer to mult anywhere? ***** Yes, another consequence of my mistake in the specifications. Kermit < [EMAIL PROTECTED] >
