Answer:
The answer to this question is given below in the explanation section.
Explanation:
The given Python code is:
>>> A = ['dog''red']
>>> B = [' cat', 'blue']
>>>C = ['fish', 'green']
We can implement an array of this data by using the dictionary in Python.
Dictionary in python:
A dictionary in python stores (key-value) pairs. For example, we can implement the -given arrays A, B, and C in the dictionary as given below:
d={'dog : red', 'cat : blue', 'fish : green'}
print(d['dog']) # Get an entry from a dictionary; prints "red"
print('cat' in d) # Check if a dictionary has a given key; prints "True"
d['fish'] = 'black' # Set an entry in a dictionary
print(d['fish']) # Prints "black"
# print(d['elephant']) # KeyError: 'elephant' not a key of d
print(d.get('elephant', 'N/A')) # Get an element with a default; prints "N/A"
print(d.get('fish', 'N/A')) # Get an element with a default; prints "black"
del d['dog'] # Remove an element from a dictionary
print(d.get('dog', 'N/A')) # "dog" is no longer a key; prints "N/A"
