prime numbers pyhton code example

Example 1: prime number in python

def prime(num):
    if num>1:
        s=int(num/2)
        for i in range(2,s+1):
            if num%i==0:
                return("not prime")
                break
        return("prime")
print(prime(239))

Example 2: python is a number prime

def prime(n):
  if min(n//3,n//2,n//5) == 0: 
    return True
  elif min(n%3,n%2,n%5) == 0: 
    return False
  else: 
    return True

# Super easy to use, and maximum efficiency! No imports needed.
print(prime(732))

def divis(n):
  if prime(n) == True: 
    return (1,n)
  for i in [2,3,5]:
    if n%i == 0: 
      return (i,n/i)

print(divis(735))
# Gets a divisibility pair: Make sure you have also implemented prime() or it may not work.

Example 3: python calculate prime numbers until numer

until = 20
[n for n in range(2, until) if all(n % m != 0 for m in range(2, n-1))]
