质数列表生成器在运行时立即关闭 [英] Prime numbers list generator immediately closing when run

问题描述

我正在尝试制作一个质数列表.

I'm trying to make a list of prime numbers.

primes = []
num=int
for num in range (2,100):
    for x in range (2, num):
        if (num % x) == 0:
            pass
        else:
            primes.append(num)
            break
print(primes)
input()

但是当我尝试打开 .py 文件时它会立即关闭.我认为代码有问题.

but it closes immediately when I try to open the .py file. I think there is a problem with the code.

推荐答案

您的代码执行并完成，但它没有计算素数列表，因为它包含一个错误:

Your code executes and finishes, but it does not compute a list of prime numbers because it contains an error:

当您测试每个 num 以查看它是否为质数时，您可以测试所有可能的除数(正如您尝试做的那样)，如果找到单个除数则​​退出.如果在测试完所有除数后都没有找到除数，则仅将您的数字添加到列表中

When you test each num to see if it's prime, you can test all possible divisors (as you try to do) and quit if you find a single divisor. If no divisor has been found when you've tested them all, only then add your number to the list

此外，不需要 num=int 行

primes = []

for num in range (2,100):
    is_prime=True
    for x in range (2, num):
        if (num % x) == 0:
            is_prime=False
            break
    if is_prime:
       primes.append(num)

print(primes)
input()
