我的代码有什么问题，请检查我的代码？

扎眼的阳光 python 384

原文标题 ：What is wrong with my code, Please check my code?

a = int(input())
if (a==0 or a==1 or a<1):
  print("factorial is one") 
else:
  fact =1
  while(a>1):
   fact = fact *a
   a = a-1
   print("factorial:",fact)

和输出就像：6factorial：6factorial：30factorial：120factorial：360factorial：720

但我只想要720

    压痕问题，在外面做打印while

    a = int(input())
if (a==0 or a==1 or a<1):
  print("factorial is one") 
else:
  fact =1
  while(a>1):
   fact = fact *a
   a = a-1
  print("factorial:",fact)

    N.B:the best way to do a factorial, is use a recursive function

    def fact(n):
  if n == 1:
    return 1
  else:
    return n * fact(n-1) 


number = int(input('Your nuumber'))

print('factorial', fact(number))
