python prime check
def isPrime(n): if n<2: #1, 0 and all negative numbers are not prime return False elif n==2: #2 is prime but cannot be calculated with the formula below becuase of the range function return True else: for i in range(2, n): if (n % i) == 0: #if you can precisely divide a number by another number, it is not prime return False return True #if the progam dont return False and arrives here, it means it has checked all the numebrs smaller than n and nono of them divides n. So n is prime
prime checker in python
#make the function #to do this all hte vairibles go in side the function def CheckIfPrime (): a1 = input("which number do you want to check") a = int(a1)#you need the checking number as an int not an str b = 2 #the number to check againts c = ("yes") while b < a:#run the loop if a%b == 0:#check if the division has a remainder c = ("no")#set the answer b = b+1 print(c)#print the output CheckIfPrime ()#call the function
