多次调用函数并传递参数

Question

I want to call the function multiple time and use it's returned argument everytime when it's called. For example:

  def myfunction(first, second, third):
         return (first+1,second+1,third+1)

1st call: myfunction(1,2,3) 2nd call is going to be pass returned variables: myfunction(2,3,4) and loop it until defined times. How can I do such loop? Thank you!

Answer 1

a,b,c = 1,2,3
while i<n:
    a,b,c = myfunction(a,b,c)
    i +=1

Answer 2

def myF(x,y,z,i):
    print x, i
    while i:
        x += 1
        i -= 1
        return myF(x,i)

This will keep calling myF until i is 0 which will break the while loop, example:

>>> myF(1,10)
1 10
2 9
3 8
4 7
5 6
6 5
7 4
8 3
9 2
10 1
11 0

For three arguments, you can do as follows:

>>> def myF(x,y,z,i):
        print x,y,z,i
        while i:
            i -= 1
            x,y,z = map(lambda s:s+1,(x,y,z))
            return myF(x,y,z,i)


>>> 
>>> 
>>> myF(1,1,1,10)
1 1 1 10
2 2 2 9
3 3 3 8
4 4 4 7
5 5 5 6
6 6 6 5
7 7 7 4
8 8 8 3
9 9 9 2
10 10 10 1
11 11 11 0
