Write a Python program that takes a String as an input from the user and counts the frequency of each character using a dictionary. For solving this problem, you may use each character as a key and its frequency as values. [You are not allowed to use the count() function] Hint: You can create a new dictionary to store the frequencies. You may ignore case for simplicity (i.e. may consider P and p to be the same). =================================================================== Sample Input: "Python programming is fun" Sample Output: {'p': 2, 'y': 1, 't': 1, 'h': 1, 'o': 2, 'n': 3, 'r': 2, 'g': 2, 'a': 1, 'm': 2, 'i': 2, 's': 1, 'f': 1, 'u': 1} 

Suppose you have been given the following list of tuples.

list_1 = [("a", 1), ("b", 2), ("a", 3), ("b", 1), ("a", 2), ("c", 1)]

Write a Python program that converts this list of tuples into a dictionary and then prints the

dictionary.

[You are not allowed to use set]

Hint: Think of membership operators (in and not in).

===================================================================

Output:

{'a': [1, 3, 2], 'b': [2, 1], 'c': [1]}

Write a python program that takes an input from the user and finds the number of times that the

input is present in a given tuple.

===================================================================

Example 1:

Given tuple: (10, 8, 5, 2, 10, 15, 10, 8, 5, 8, 8, 2)

Sample Input 1:

8

Sample Output 1:

8 appears 4 times in the tuple

===================================================================

Example 2

Given tuple: (10, 8, 5, 2, 10, 15, 10, 8, 5, 8, 8, 2)

Sample Input 2:

1

Sample Output 2:

1 appears 0 times in the tuple

===================================================================
