e python Write a function named concat_keys whose parameter is an object/dictionary. The parameter will have strings as keys and integers as values. The function should return a string whose value is the concatenation of the parameter's keys with a space added after each key.

Write a function named count_vowels that accepts a string as an argument. The function should count the number of times each vowel (the letters a, e, i, o, and u) appears in the string, and store those counts in a dictionary. When the function ends, the dictionary should have exactly 5 elements. In each element, the key will be a vowel (lowercase) and the value will be the number of times the vowel appears in the string.

This section has been set as optional by your instructor. OBJECTIVE: Write a program in Python that prints the middle value of a dictionary's values, using test_dict from the test_data.py module. NOTE: test_dict is created & imported from the module test_data.py into main.py Example 1: test dict = {'a':1,'b':9,'c':2,'d':5} prints 5 Example 2: test_dict = {'b':9,'d':5} prints 5 Hint: You may(or may not) find the following function useful: list.sort() which sorts the elements in a list. Note: the result is automatically stored in the original list, and return value from the function is None Туре list = [1, 2,3,2,1] After calling: list = [1,1,2,2,3] list.sort(), 339336.2266020 x3zgy7 LAB 13.11.1: Middlest Value (Structured Types) АCTIVITY 0/11 File is marked as read only Current file: test_data.py 1 #This module creates the test_dict to be used in main.py 2 #Reads input values from the user & places them into test_dict 3 dict_size = int(input()) #Stores the desired size of test_dict. 4…

Assume the variable definitions references a dictionary.  Write an if statement that determines whether the key 'marsupial' exists in the dictionary.  If so, delete 'marsupial' and its associated value.   If the key is not in the dictionary, display a message indicating so.
