You are required to complete 5 functions for hashtable which is a list. (Must be done in Python)

Please refer to the question for each function. Also, there are test codes and required outputs for all of the functions.

Function 1:

Function 2:

Function 3:

Function 4:

Function 5

Write a function called insert_key0 that inserts a key into a hashtable, represented by a list, using the hash function: index = key % (length of hashtable) As parameters the function will take a key to insert and a list representing the hashtable. You may assume no collisions will occur and there will be space for the value. The 'None' value will be used to represent empty positions in the hashtable. e.g: hashtable [0,1,2,3,None,5,None,7] insert_key(12, hashtable) print(hashtable) output: [0, 1, 2, 3, 12, 5, None, 7] Answer: (penalty regime: 0 %) 1-] def insert_keyCkey, hashtable)
