我已经为number的collatz模式编写了一个python代码，我想计算它达到1所需的步骤数。我怎么做？

Question

def collatz(n):
    while n > 1:
        print(n, end=' ')
        if (n % 2):
            # n is odd
            n = 3*n + 1
        else:
            # n is even
            n = n//2
    print(1, end='')
 
 
n = int(input('Enter n: '))
print('Sequence: ', end='')
collatz(n)

Answer 1

只要加一个计数器就行了

def collatz(n):
    counter = 0
    while n > 1:
        counter += 1
        print(n, end=' ')
        if (n % 2):
            # n is odd
            n = 3*n + 1
        else:
            # n is even
            n = n//2
    print(1, end='\n')
    print("Number of steps until convergance :" + str(counter))
 
 
n = int(input('Enter n: '))
print('Sequence: ', end='')
collatz(n)
