Control flow: while loop

CLick here to download IPYTHON notes for this lecture

    python while loop statement: As many people are asking questions about prime numbers program, please check this one

p = 10
q = 16
# we will keep checking every number starting from p to q
for i in range(p, q):
	print("we are checking ", i, "is prime or not")
	# we assume that i is not divisible by any number except 1 and i
	is_i_divisble_by_any_number = False
	# now, we will start searching for a number that devides i in range 2, i
	for j in range(2, i):
		# lets check if j devides i or not
		if i % j == 0:
			# since there exist a number j that devides i, our assumption is wrong
			# so we are setting is_i_divisble_by_any_number = True
			is_i_divisble_by_any_number = True
			print(" the number ", j, "devides ", i)
			# since we got the number, so we proved that its not a prime numer
			# so we will break it
			break
	# if our assumption still holds even after the search in range(2, i)
	# we declare i as prime number
	if is_i_divisble_by_any_number == False:
		print(i, "is a prime number")
	else:
		print(i, "is not a prime number")
	print("="*50)

Output of the of the code

we are checking  10 is prime or not
 the number  2 devides  10
10 is not a prime number
==================================================
we are checking  11 is prime or not
11 is a prime number
==================================================
we are checking  12 is prime or not
 the number  2 devides  12
12 is not a prime number
==================================================
we are checking  13 is prime or not
13 is a prime number
==================================================
we are checking  14 is prime or not
 the number  2 devides  14
14 is not a prime number
==================================================
we are checking  15 is prime or not
 the number  3 devides  15
15 is not a prime number
