Example 1
# Python program explaining
# the dictionary.copy() method
# initialising the dictionary
fruits = {
"banana": "apple",
"orange": "mango",
"grapes": 5
}
# printing the dictionary
print("Dictionary:",fruits)
# copying the dictionary elements.
dictionary2= fruits.copy()

Dictionary: {'grapes': 5, 'orange': 'mango', 'banana': 'apple'}
After the copying the dictionary...
Dictionary2: {'grapes': 5, 'orange': 'mango', 'banana': 'apple'}
Example 2
# Python program explaining
# the dictionary.copy() method
#initializing the dictionary
dictionary = {1: "numbers", 2: "digits"}
# copying the elements of dictionary in dictionary1
dictionary1 = dictionary.copy()
print('dictionary: ', dictionary)
print("After copying the dictionary elements in dictionary1...")
print('dictionary1: ', dictionary1)
Output
dictionary: {1: 'numbers', 2: 'digits'}
After copying the dictionary elements in dictionary1...
dictionary1: {1: 'numbers', 2: 'digits'}
Example 3
# Python program explaining
# the dictionary.copy() method
dictionary = {1:'one', 2:'two',3:'three'}
# copying the original dictionary using copy() function
copyElement = dictionary.copy()
# removing all elements from the dictionary
# Only new dictionary becomes empty as copy()
# does shallow copy.
copyElement.clear()
# printing the dictionary after clearing all elements
print('new: ', copyElement)
# printing the original elements
print('original: ', dictionary)
Output
new: {}
original: {1: 'one', 2: 'two', 3: 'three'}
