判断随机数的函数：

1，流程图：

 

 

try:
    import random
    question=input("would you want to play a number game?：")
    if question=="yes":
        value=random.randint(0,100)
        ret1=0
        ret2=100
        while True:
            count=1
            question_two=(int(input("Try to guess the number: ")))
            if question_two>value:
                     print("请输入%s到%s之间的数"%(ret1,question_two))
                     ret2=question_two
                     continue
            elif question_two<value:
                     print("请输入%s到%s之间的数"%(question_two,ret2))
                     ret1=question_two
                     continue
            else:
                 print("That\'s it")
                 question_three=input("would you like to play again?:")
                 if question_three=='yes':
                     ret1=0
                     ret2=100
                     value=random.randint(0,100)
                     continue
                 else:
                    break
    else:
       question=="no"
except Exception as f:
    print('错误是%s'%f)

 2.产生一个菱形：

def func(f):
    count=1
    def inner(*args):
        while True:
            nonlocal count
            if count<num:
                print((2*count-1)*'*')
                count+=1
            else:
                break
        f(*args)
    return inner
@func
def func1(num2):
    while True:
        print('*'*(2*num2-1))
        num2-=1
        if num2==0:
            return
num1=int(input('请输入一个奇数'))
num=num1//2+1
func1(num)

num=int(input('请输入一个数字'))
num1=num//2+1
count=1
while True:
    if count<num1:
        print((2*count-1)*'*')
        count+=1
    elif count==num1:
        flag=num1
        count=num
        print((2*flag-1)*'*')
    else:
        flag-=1
        print((2*flag-1)*'*')
        if flag==0:
            break
