Visual Presentation:

Python Dictionary: Drop empty Items from a given Dictionary.

Sample Solution:

Python Code:

# Create a dictionary 'dict1' with keys and associated values, including a 'None' value.
dict1 = {'c1': 'Red', 'c2': 'Green', 'c3': None}

# Print a message indicating the start of the code section and the original dictionary.
print("Original Dictionary:")
print(dict1)

# Print a message indicating the intention to create a new dictionary without empty items.
print("New Dictionary after dropping empty items:")

# Use a dictionary comprehension to create a new dictionary that excludes items with 'None' values.
# Iterate through the key-value pairs in 'dict1' and include them in the new dictionary if the value is not 'None'.
dict1 = {key: value for (key, value) in dict1.items() if value is not None}

# Print the new dictionary containing only non-empty items.
print(dict1) 

Sample Output:

Original Dictionary:

{'c1': 'Red', 'c2': 'Green'}
