Python - prime numbers generator

Question

Hello
Why my code don't work?

numb = int(input())
primeNumb = [2,]
i = 3
b = True
z = 2

while i < numb:
while b == True:
while z < i:
if i % z == 0:
b = False
z = z + 1
print(primeNumb)
primeNumb.append(i)
i = i + 1
print(primeNumb)

Answer 1

You must reset z and b to its original value somewhere in the loops. I solved it like this:

while i < numb:
while (z < i and b == True):
if i % z == 0:
b = False
z = z + 1
z = 2 # reset z
if b == True:
primeNumb.append(i)
b = True # reset b
i = i + 1
print(primeNumb)

Answer 2

Dawid Uzarski I think there is a logic error bcoz, let numb=9, i=8 and z=4, it satisfies all the above conditions and 8%4 is 0,
Therefore according to your code 8 is a prime number but it is not.

Answer 3

Ohh thx Paul Jacobs I miss that

Answer 4

Dawid Uzarski by version of finding primes in an given range.
