Python Generate random number between x and y which is a multiple of 5

Question

I ve read the manual for pseudo-randomness in Python  and to my knowledge  you can only generate numbers up to a given maximum value  i e  0-1  0-30  0-1000  etc   I want to    a  Generate a number between two ints  i e  5-55  and b  Only include multiples of 5  or those ending in 5 or 0  if that s easier    I ve looked around  and I can t find anywhere that explains this

Create an integer random between e g  1-11 and multiply it by 5  Simple math   import random for x in range 20     print random randint 1 11  5  print   produces e g   5 40 50 55 5 15 40 45 15 20 25 40 15 50 25 40 20 15 50 10

If you don t want to do it all by yourself  you can use the random randrange function   For example import random  print random randrange 10  25  5  prints a number that is between 10 and 25  10 included  25 excluded  and is a multiple of 5  So it would print 10  15  or 20

The simplest way is to generate a random nuber between 0-1 then strech it by multiplying   and shifting it  So yo would multiply by  x-y   so the result is in the range of 0 to x-y  Then add x and you get the random number between x and y      To get a five multiplier use rounding  If this is unclear let me know and I ll add code snippets
