#1 Tab键:
1)控制缩进
2)IDLE智能补全
#2 =等号:
1)=:表示赋值
2)==:表示判断
#3 流程图:
print('..........小甲鱼_1..........')
temp=input('猜测小甲鱼心里想的是哪个数字:')
guess=int(temp)
if guess==8:
print('中了')
print('哼,中了也没有奖励')
else:
print('猜错啦,小甲鱼想的是8!')
print('游戏结束,不玩了。')
改进:
1)条件 if-else
2)循环 while and
3)import random 模块:random.randint函数-返回一个随机的整型
import random
secret = random.randint(1,10)
print('..........小甲鱼_1..........')
_continue = input('''是否参与游戏?
是:Y
''')
if _continue == 'Y':
temp = input('猜测小甲鱼心里想的是哪个数字:')
guess = int(temp)
while guess and _continue == 'Y':
if guess == secret:
print('中了')
print('哼,中了也没有奖励')
break
else:
if guess > secret:
print('大了大了!')
_continue = input('''是否继续猜测?
继续:Y
''')
temp = input('继续猜测小甲鱼心里想的是哪个数字:')
guess = int(temp)
else:
print('小了小了!')
_continue = input('''是否继续猜测?
继续:Y
''')
temp = input('继续猜测小甲鱼心里想的是哪个数字:')
guess = int(temp)
else:
print('游戏结束,不玩了。')

>>> help(input)
Help on built-in function input in module builtins:
input(...)
input([prompt]) -> string
Read a string from standard input. The trailing newline is stripped.
If the user hits EOF (Unix: Ctl-D, Windows: Ctl-Z+Return), raise EOFError.
On Unix, GNU readline is used if enabled. The prompt string, if given,
is printed without a trailing newline before reading.
