Remove All Keys From Python Dictionary

In this tutorial, we will look at how to remove all the key-value pairs from a Python dictionary with the help of some examples.

How to remove all items from a dictionary in Python?

remove all items from a python dictionary

You can use the Python dictionary clear() function to remove all the key-value pairs from a dictionary. The following is the syntax –

# remove all dictionary items
my_dict.clear()

It removes all the items in the dictionary in place thereby resulting in an empty dictionary.

Let’s look at some examples.

You have a dictionary containing the names to department mapping of employees in an office. Unfortunately, management has decided to close down this branch and lay off the employees.

You need to update the employee dictionary such that there are no items present in the dictionary.

# create a dictionary
employees = {
    "Jim": "Sales",
    "Dwight": "Sales",
    "Angela": "Accounting"
}
# remove all items from dictionary
employees.clear()
# display the dictionary
print(employees)

Output:

{}

Here we used the dictionary clear() function to remove all the key-value pairs from the employees dictionary. The employees dictionary is now empty.

Note that the clear() function modifies the dictionary in-place.

Let’s look at another example.

# create a dictionary
test_scores = {
    "Chad": 91,
    "Hasan": 98
}
# remove all items from dictionary
test_scores.clear()
# display the dictionary
print(test_scores)

Output:

{}

The test_scores dictionary originally contained two key-value pairs. We get an empty dictionary after using the dictionary clear() function.
