关于while 循环
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） 本帖最后由 suchocolate 于 2021-10-7 11:19 编辑
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。 [[, print()] for j in range(10)] 0 x 0 = 01 x 0 = 02 x 0 = 03 x 0 = 04 x 0 = 05 x 0 = 06 x 0 = 07 x 0 = 08 x 0 = 09 x 0 = 0
