The Python code is given below with code and output screenshot Algorithm Check if the list is empty. If yes, return an empty list Start a loop through the list and store frequency of each element into a dictionary If element already exist in list, then add 1 to its frequency If element was not found in list previously, then make the frequency 1 Check if frequency of all elements of the list are same. If yes return the full list If any element has frequency greater than 1, store the element into a separate list an return it as answerdef find_mode(lst): if len(lst) == 0: return [] f = {} for i in lst: if i in f: f[i] += 1 else: f[i] = 1 ans = [] if len(set(f.values())) == 1: return lst for i in f: if f[i] > 1: ans.append(i) return ans print(find_mode ([12, 11, 12, 3, 6, 7, 9]))print(find_mode (["hat", "sweater", "pants", "sock"]))print(find_mode ([11.4, 9.9, 13.0, 77.1, 11.4, 13.0, 9.9, 15.88]))print(find_mode([1,2,3,4,5]))

2A in Python language please:

User Defined Functions and Recursion
Background
The purpose of this Programming is to practice writing function definitions, using functions inside of
other functions, and using recursion to solve complex problems.
Restrictions
Any function that violates the following:
• You are not allowed to import anything
•
You are not allowed to use the global keyword, nor should you have any global variables. (In
other words, do not create any variables outside of a function definition.
You are not allowed to use slicing (except for the 5th function add_chars)
•
No built-in function except round(), range(), and len() is allowed
• From list methods, you are allowed to use .append(), .insert(),.remove(), or del
•
From dictionary methods, you are allowed to use .keys(), .values(),.items()
Testing
In addition to the examples in the tester file, you should also devise your own test cases for your code.
Develop additional test cases, on your own, to make sure that you haven't missed anything (empty lists,
different sized lists, etc) and your code is correct. The goal is to keep your focus on writing correct code.
Functions
In this Programming, you will be writing and calling a handful of functions (five). From the description,
you will generate the signature, and function body for each function. (The examples can give you hints
about the signatures!)

(2) find_mode ()
#you have to determine the signature
Description: Design and write a function called find_mode() which determines which element(s)
from a list occurs the most. The mode is returned as a list, with one or more elements in it. (If
there is a tie for the most-occurring, then both/all must be in the list.) If the list is empty, the
mode is and empy list.
Parameters: (read the description carefully)
Return value: (read the description carefully)
Assumptions:
• The items in the list are the same data type.
• The list is non-empty.
Examples:
[12]
find_mode ([12, 11, 12, 3, 6, 7, 9])
find_mode (["hat", "sweater", "pants", "sock"])
→ ["hat", "sweater", "pants", "sock"]
find_mode ([11.4, 9.9, 13.0, 77.1, 11.4, 13.0, 9.9, 15.881)
[9.9, 11.4, 13.0]
find_mode ([1,2,3,4,5]) [1,2,3,4,5]
