Python實現求1-1000以內的素數

def func():
    for i in range(2,1000):
        # count表示被整除的次數
        count = 0
        for j in range(1,i+1):
            if i%j==0:
                count+=1
            # count==2說明，該數字只能被1和它本身整除
            if count==2:
                if i==j:
                    print(i)
