If you also need the removed value, use my_dict.pop(key). Both raise KeyError when the key is missing; pop can instead return a fallback if you provide one.
Remove an entry by key
A dictionary entry consists of a key and its associated value. Python removes the entry by key—not by searching for its value. Use del when you only need to delete the entry:
person = {"name": "Ada", "age": 36}
del person["age"]
print(person) # {'name': 'Ada'}del person["age"] changes the existing dictionary in place. It raises KeyError if "age" is not a key in the dictionary.
Choose the removal method you need
| Need | Operation | What happens |
|---|---|---|
| Delete a known key without using its value | del d[key] |
Removes the entry; raises KeyError if the key is absent. |
| Delete a key and retrieve its value | d.pop(key) |
Removes and returns the value; raises KeyError if the key is absent. |
| Delete a key only if present | d.pop(key, default) |
Removes and returns the value if present; otherwise returns default. |
| Remove the most recently inserted entry | d.popitem() |
Removes and returns a (key, value) pair; raises KeyError if the dictionary is empty. |
| Remove every entry | d.clear() |
Empties the dictionary. |
These operations and their behavior are documented in the Python 3.14.8 built-in types reference.
#1 Best Overall
Use pop when you need the removed value
pop removes the entry and returns its value, which is useful when the value should be saved or used immediately:
person = {"name": "Ada", "age": 36}
name = person.pop("name")
print(name) # Ada
print(person) # {'age': 36}To avoid an error when a key may be absent, pass a default:
age = person.pop("age", None)If "age" is missing, this returns None without changing the dictionary. Use this form only when None is an acceptable fallback. If None could also be a stored value and you need to tell that apart from a missing key, use a unique sentinel:
missing = object()
value = person.pop("age", missing)
if value is missing:
print("No age entry")Remove the latest entry or empty the dictionary
Remove the most recently inserted pair
Call popitem() when you want to remove and receive the most recently inserted key-value pair:
last_key, last_value = person.popitem()Dictionaries preserve insertion order, and popitem() removes pairs in last-in, first-out order in current Python; that order has been guaranteed since Python 3.7. Calling it on an empty dictionary raises KeyError.
Remove all entries
Call clear() to empty the dictionary in place:
person.clear()Afterward, the dictionary still exists, but it contains no entries.

del and pop take a key, not a value. Python dictionaries do not provide a remove(value) method. If your goal is to exclude entries with a particular value, build a new dictionary by filtering its items:
scores = {"Ada": 10, "Lin": 7, "Sam": 10}
without_tens = {
key: value
for key, value in scores.items()
if value != 10
}
print(without_tens) # {'Lin': 7}This creates a new dictionary and leaves scores unchanged. The dictionary removal operations are described in the official Python documentation.
