break 结束循环
continue 结束当前本次循环进入下次循环
使用for循环,和while循环,打印九九乘法表:
x = 1
y = 1
while x < 10 and y <= x < 10:
print('%d*%d=%d'%(x,y, x*y), end = '\t')
if x > y:
y += 1
else:
x += 1
y = 1
print('\n')
continue
方法二:
x = 1
while x < 10:
for y in range(1, x+1):
print('%d*%d=%d'%(x,y,x*y), end=' ')
print('\n')
x += 1
