Python recursive function

A nested list of integers is a list that stores integers in some hierarchy. That is, its elements are integers and/or other nested lists of integers. For example nested lst-[[1, 2], 3, [4, [5, 6, [7, 811 is a nested list of integers. Give a recursive implement to the following function: def flat list (nested lst, low, high) The function is given a nested list of integers nested list, and two indices: low and high (low Shigh), which indicate the range of indices that need to be considered. The function should flatten the sub-list at the positions low, low+1, .., high of nested list, and return this flattened list. That is, the function should create a new 1-level (non hierarchical) list that contains all the integers from the low...high range in the input list. For example, when callingflat 1list to flatten the list nested lst demonstrated above (the initial call passes low-0 and high-2), it should create and return [1, 2, 3, 4, 5, 6, 7, 8]
