考拉兹猜想--代码实现

def collatz(number):
    while True:
        if number%2==0:
            number=number//2
            print(number)
        elif number%2==1 and number!=1:
            number=number*3+1
            print(number)
        else:
            break
print('enter number:')
try:
    number=int(input())
    collatz(number)
except ValueError: #检测是否输入非整数
    print('请输入整数:')
    number=int(input())
    collatz(number)
