python 的循环语法

1，while 语句
count = 0
while (count < 9):
print (‘The count is:’, count)
count = count + 1

	print ("Good bye!")

2，continue 和 break 的区别
i = 1
while i < 10:
i += 1
if i%2 > 0: # 非双数时跳过输出
continue
print (i) # 输出双数2、4、6、8、10

	i = 1
	while 1:            # 循环条件为1必定成立
	    print (i)         # 输出1~10
	    i += 1
	    if i > 10:     # 当i大于10时跳出循环
	        break

3，无线循环
var = 1
while var == 1 : # 该条件永远为true，循环将无限执行下去
num = input(“Enter a number :”)
print ("You entered: ", num)

	print ("Good bye!")
