Dictionary is used in manifold practical applications such as day-day programming, web development and AI/ML programming as well, making it a useful container overall. Hence, knowing the ways for achieving different tasks related to dictionary usage always is a plus.
Example
# using del # Initializing dictionary test_dict = {"Vishesh" : 29, "Ram" : 21, "Vishal" : 27, "Prashant" : 25} # Printing dictionary before removal print ("The dictionary before performing remove is : " + str(test_dict)) # Using del to remove a dict del test_dict['Vishal'] # Printing dictionary after removal print ("The dictionary after remove is : " + str(test_dict)) # using pop() # Initializing dictionary test_dict = {"Vishesh" : 29, "Ram" : 21, "Vishal" : 27, "Prashant" : 25} # Printing dictionary before removal print ("The dictionary before performing remove is : " + str(test_dict)) # Using pop() to remove a dict. pair removed_value = test_dict.pop('Ram') # Printing dictionary after removal print ("The dictionary after remove is : " + str(test_dict)) print ("The removed key's value is : " + str(removed_value)) # Using pop() to remove a dict. pair doesn't raise exception # assigns 'No Key found' to removed_value removed_value = test_dict.pop('Nilesh', 'No Key found') # Printing dictionary after removal print ("The dictionary after remove is : " + str(test_dict)) print ("The removed key's value is : " + str(removed_value)) # using items() + dict comprehension # Initializing dictionary test_dict = {"Vishesh" : 29, "Ram" : 21, "Vishal" : 27, "Prashant" : 25} # Printing dictionary before removal print ("The dictionary before performing remove is : " + str(test_dict)) # Using items() + dict comprehension to remove a dict. pair new_dict = {key:val for key, val in test_dict.items() if key != 'Prashant} # Printing dictionary after removal print ("The dictionary after remove is : " + str(new_dict)) '
