[已解决]关于while 循环

jessie0621

for i in range(10):
    for j in range(10):
        while (i==0 or j==0):
            continue
        print (str(i) + " x " + str(j) + " = " + str(i*j))

为什么这个不会输出任何值吗，i和j在一个范围10里面会不会改变（从0-9）

i和j开始都是0，while成立，执行while中内容，然后里头只有continue，i和j的值没有改变机制，while又成立，又执行while中的continue，死循环。
