Write a Python program to find the length of a dictionary of values.

Visual Presentation:

Sample Solution:

Python Code:

``````# Define a function 'test' that calculates the length of the values in a dictionary and returns a new dictionary with values as keys and their lengths as values.
def test(dictt):
result = {}
for val in dictt.values():
# Calculate the length of each value and store it as a key-value pair in the 'result' dictionary.
result[val] = len(val)
return result

# Create a dictionary 'color_dict' with integer keys and color values.
color_dict = {1: 'red', 2: 'green', 3: 'black', 4: 'white', 5: 'black'}

# Print a message indicating the start of the code section and the original dictionary.
print("\nOriginal Dictionary:")
print(color_dict)

# Print a message indicating the intention to calculate the length of dictionary values.
print("Length of dictionary values:")

# Call the 'test' function to calculate the length of values in the dictionary and print the result.
print(test(color_dict))

# Create a dictionary 'color_dict' with string keys and names as values.
color_dict = {'1': 'Austin Little', '2': 'Natasha Howard', '3': 'Alfred Mullins', '4': 'Jamie Rowe'}

# Print a message indicating the start of the code section and the original dictionary.
print("\nOriginal Dictionary:")
print(color_dict)

# Print a message indicating the intention to calculate the length of dictionary values.
print("Length of dictionary values:")

# Call the 'test' function to calculate the length of values in the dictionary and print the result.
print(test(color_dict))
```
```

Sample Output:

```Original Dictionary:
{1: 'red', 2: 'green', 3: 'black', 4: 'white', 5: 'black'}
Length of dictionary values:
{'red': 3, 'green': 5, 'black': 5, 'white': 5}

Original Dictionary:
{'1': 'Austin Little', '2': 'Natasha Howard', '3': 'Alfred Mullins', '4': 'Jamie Rowe'}
Length of dictionary values:
{'Austin Little': 13, 'Natasha Howard': 14, 'Alfred Mullins': 14, 'Jamie Rowe': 10}
```
