How do you check whether a number is divisible by another number Python

Question

I need to test whether each number from 1 to 1000 is a multiple of 3 or a multiple of 5  The way I thought I d do this would be to divide the number by 3  and if the result is an integer then it would be a multiple of 3  Same with 5    How do I test whether the number is an integer   here is my current code   n   0 s   0  while  n  lt  1001       x   n 3     if isinstance x   int  long            print  Multiple of 3           s   s   n     if False          y   n 5         if isinstance y   int  long                s   s   n      print  Number        print n     print  Sum       print s     n   n   1

a   1400 a1   5 a2   3  b  str a a1  b1   str a a2  c  b  len b -2  len b   c1  b  len b1 -2  len b1   if c      0       print  yeah for 5    if c1      0       print  yeah for 3

For small numbers n 3    0 will be fine  For very large numbers I propose to calculate the cross sum first and then check if the cross sum is a multiple of 3   def is divisible by 3 number       if sum map int  str number      3    0          my bool   False     return my bool

Try this      public class Solution      public static void main String   args        long t   1000      long sum   0       for int i   1  i lt t  i                 if i 3    0    i 5    0                   sum   sum   i                                  System out println sum

You do this using the modulus operator     n   k    0   evaluates true if and only if n is an exact multiple of k  In elementary maths this is known as the remainder from a division   In your current approach you perform a division and the result will be either   always an integer if you use integer division  or always a float if you use floating point division    It s just the wrong way to go about testing divisibility

You can simply use   Modulus operator to check divisibility  For example  n   2    0 means n is exactly divisible by 2 and n   2    0 means n is not exactly divisible by 2

This code appears to do what you are asking for   for value in range 1 1000       if value   3    0 or value   5    0          print value    Or something like  for value in range 1 1000       if value   3    0 or value   5    0          some list append value    Or any number of things

I had the same approach  Because I didn t understand how to use the module    operator    6   3   0  This means if you divide 6 by 3 you will not have a remainder  3 is a factor of 6    Now you have to relate it to your given problem   if n   3    0  This is saying  if my number n  is divisible by 3 leaving a 0 remainder    Add your then print  return  statement and continue your

The simplest way is to test whether a number is an integer is int x     x  Otherwise  what David Heffernan said

You can use   operator to check divisiblity of a given number  The code to check whether given no  is divisible by 3 or 5 when no  less than 1000 is given below   n 0 while n lt 1000      if n 3  0 or n 5  0          print n  is multiple of 3 or 5      n n 1
