用python2-100之间的素数只能被1和自己整除的自然数要求用while和for两种语句分别实现。

用while语句实现：

i = 2
while i <= 100:
    j = 2
    while j <= i:
        if i % j == 0 and i != j:
            break
        j += 1
    else:
        print(i),
    i += 1

用for语句实现：

for i in range(2, 101):
    for j in range(2, i):
        if i % j == 0:
            break
    else:
        print(i),
