You can remove all items from a dictionary in Python using the clear() method. This method empties the dictionary, leaving it with zero items. It does not take any parameters and does not return a value. Here's how you use it:

python

my_dict = {'a': 1, 'b': 2, 'c': 3}
my_dict.clear()
print(my_dict)  # Output: {}

After calling clear(), the dictionary becomes empty {}

. Alternatively, you can also remove all items by reassigning the dictionary to an empty dictionary:

python

my_dict = {'a': 1, 'b': 2, 'c': 3}
my_dict = {}
print(my_dict)  # Output: {}

Or, if you want to remove items one by one, you could iterate over the keys and delete them using del in a loop, but this is less efficient than clear()

. In summary, the simplest and most common way to remove all items from a dictionary is to use the clear() method.
