使用 arrays 进行动态迭代。 可能吗？ 如果是的话怎么办？

Question

What I am trying to achieve is a couple of nested loops, where the number of nests will be dynamic. So if for example there is 2 nested loops needed for the program then it will go

for i in abc:
   for j in def:
       codes

So, if there is a need for 3 nested loops that is set by multiple conditions within the program, then the loop will be dynamically set, and that's what I don't know how to do or if it can be done. So I want it to be automatically do

 for i in abc:
       for j in def:
           for k in ggh:
               codes

So you can see I manually wrote the third nest, but can it be done automatically? WITH PYTHON...

Answer 1

You can use a recursive function:

l = [1, 2, 3, 4, [1, 2, 3, 4, [1, 2, 3], [1, 2]], [1, 2], [1, 2, 3, 4]]

def recursive_iter(list_):
    for i in list_:
        if isinstance(i, (list, tuple)):
            recursive_iter(i)
        else:
            print(i)

recursive_iter(l)
