clear() method for deleting all elements of a dictionary

clear(), takes no argument.

Returns : None. ( the parent dictionary elements are removed )

my_dict={'a':'Alex','b':'Ronald','c':'Ron'}
my_dict.clear()
print(my_dict)

Output is here

{}

We can check the data type of the output

my_dict={'a':'Alex','b':'Ronald','c':'Ron'}
my_dict.clear()
print(type(my_dict))

Output

<class 'dict'>

Difference between del and clear

clear is a method of directory class, del is a keyword in Python. After using clear the list is not deleted but after using del the dictionary object is deleted.

my_dict={'a':'Alex','b':'Ronald','c':'Ron'}
del my_dict
print(my_dict) #NameError

The last line will generate error as we can't print the dictionary after deleting the same.
