I need help with problem 1, this problem needs codes to be written for the flatten function

Problem 1 Programming Problem 1 Write a function flatten that takes a list of atoms or lists (that can be of atoms or lists) and returns a flattened list. An atom is an element that cannot be broken down further into constituent pieces. The code below illustrates how this function should perform. Put your code for this function in a new module named FunctionFun.py Listing 1: Implementing Flatten. 1 x [11, 2], 13,4], 5 [6]],7] 3 z [0, 1 "small", 5, 23], "car "JJ 6 def flatten (x) 7 TODO: implement the flatten function 9 print flatten (x))
