一、if 语句
if guess == 8:
  print ('xxx')
else:
  print ('xxx')

二、while 语句
while guess != 8:
  temp = input ('xxx')
  guess = int (temp)
1、无限循环 [按 ctrl + c 强制结束]
while ‘c’：
  print ('xxx')
2、循环n次
i = n
while guess = i:
  print ('xxx')
  i = i - 1

三、语句形式
1、一行可书写多个语句
print ('xxx'); print ('yyy')
run:
xxx
yyy
2、一语句可使用反斜杠或者括号分解成多行
(3 >2 and\
2 < 1)
run:False
