• Condition comparison

  >>> 1 < 3
  True
  >>> 1 > 3
  False
  >>> 1 == 1
  True
  >>> 1 == 2
  False
  >>> 1 != 1
  False
  

• Conditional branch syntax

  Pay attention to the colon and indentation, there is no {}

  temp = input("不妨猜一下小甲鱼现在心里想的是哪个数字：")
  guess = int(temp)
  if guess == 8:
      print("我草，你是小甲鱼心里的蛔虫嘛？")
      print("哼，猜对了也没有奖励")
  else:
  	if guess > 8: #if-else语句,注意缩进和冒号
  		print("哥，大了大了")
  	else:
  		print("嘿，小了，小了")
  print("游戏结束，不玩啦")
  

• loop statement

  temp = input("不妨猜一下小甲鱼现在心里想的是哪个数字：")
  guess = int(temp)
  i=0
  while guess != 8 and i < 3: #while循环语句
      i = i + 1
      temp = input("哎呀，猜错了，请重新输入吧：")
      guess = int(temp)
      if guess == 8:
          print("我草，你是小甲鱼心里的蛔虫嘛？")
          print("哼，猜对了也没有奖励")
      else:
  		if guess > 8: #if-else语句,注意缩进和冒号
  			print("哥，大了大了")
  		else:
  			print("嘿，小了，小了")
  print("游戏结束，不玩啦~~")
  

• random function

  import random #导入random函数库
  secret = random.randint(1,5) #生成1—5之间的整数
  temp = input("不妨猜一下小甲鱼现在心里想的是哪个数字：")
  guess = int(temp)
  i=0
  while guess != secret and i < 3:
      i = i + 1
      temp = input("哎呀，猜错了，请重新输入吧：")
      guess = int(temp)
      if guess == secret:
          print("我草，你是小甲鱼心里的蛔虫嘛？")
          print("哼，猜对了也没有奖励")
      else:
          if guess > secret: #if-else语句,注意缩进和冒号
              print("哥，大了大了")
          else:
              print("嘿，小了，小了")
  print("游戏结束，不玩啦~~")
