python代码正在重新启动

Question

as I'm proceeding slowly with project Euler I started learning python. although its a great and simple language i got a bit stuck.

every code that i wrote and tried to run is automatically restarting. i think its because of the very very long loop (for example, finding the 10001 prime number), but i cant find out how to fix this issue. can anyone help me, give me a guide line or a tip?

oh, if its matters im using python 2.7

thank you!

the code as an example:

count = 0
num = 0
i = 1
def prime(num):
    if num <= 1:
        return False
    if num == 2:
        return True
    else:
        for i in range(3, num):
            if (num % i) == 0:
                return False
                break
        else:
            return True

while (count < 10001):
    if prime(i) == True:
        num == i
        count == count + 1
    i = i + 1

print num

You just need to change the == to = (twice) in your while loop:

while (count < 10001):
    if prime(i) == True:
        num = i
        count = count + 1
    i = i + 1

Then the code runs fine, and prints num as 104729
