How do you check whether a number is divisible by another number (Python)?
You do this using the modulus operator, %
n % k == 0evaluates 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.
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=0while n<1000: if n%3==0 or n%5==0: print n,'is multiple of 3 or 5' n=n+1
