Python实践：猜数字小程序Collatz序列

猜数字

• 代码

‘‘‘
猜数字小游戏，不断输入你所猜的数（1-100），程序会根据你的输入提醒你进行
适当调整所猜数的大小，直到最后猜出这个随机数
‘‘‘
guessNumber = random.randint(1,100)
print("I‘m thinking a number between 1 and 100.")

while True:
    print(‘Take a guess.‘)

    guess = int(input())

    if guess > guessNumber:
        print("It‘s too high")
    elif guess < guessNumber:
        print("It‘s to low")
    else:
        print("Congratulations, you win.")
        break

Collatz序列

• 代码

#Collatz序列
def collatz(number):
    if (number % 2 == 0):
        return number / 2
    else:
        return number * 3 + 1

print(‘Input a number.‘)

while True:
    global number1
    try:
        number1 = int(input())
    except ValueError:
        print(‘Please input a number‘)
        continue
    if collatz(number1) != 1:
        print(int(collatz(number1)))
    else:
        print(int(collatz(number1)))
        break

• 结果
