Write a Python program that takes a String as an input 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. \[You are not allowed to use the count() function\]

### Task 11 (8 points)

Write a Python program that takes a String as an input 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:** 
1. You can create a new dictionary to store the frequencies. 
2. Ignore case for simplicity (i.e. consider P and p to be the same).
3. keys need to be lower case 
4. Do not count space. Remove space before counting.

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

**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}

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

here is my code but I don't know what is wrong

def task11(in_str):
  # YOUR CODE HERE
    test_str = in_str.lower()
    dict_out = {}
    for i in test_str:
        if i in dict_out:
            dict_out[i] += 1
        else:
            dict_out[i] = 1
    return dict_out
