Python Forum

Hi,

I have been struggling with this code for four weeks and I cannot seem to rap my head around how to search for certain numbers after I run the code in python37. I can return factors for numbers I'm searching for but only if I type in a specific number. For instance if I want to see a print out of a factor for 2**11-1 which equals 23 I have to type in 2.

I do have two pieces of code the second piece allows you to see the range of items in the list and you can print factors for Non-Mersenne Primes!

Can someone help me the the second piece of code for subtraction and division? So I can output this in an automated fashion:)

Say you need to know the math for 1682 using P=29 then P=29**2*2 = 1682
