Using Dict Comprehensions
final_dict = {key: value for key, value in d.items() if key not in [key1, key2]}
where key1 and key2 are to be removed.
In the example below, keys "b" and "c" are to be removed & it's kept in a keys list.
>>> a
{'a': 1, 'c': 3, 'b': 2, 'd': 4}
>>> keys = ["b", "c"]
>>> print {key: a[key] for key in a if key not in keys}
{'a': 1, 'd': 4}

Python - Remove Multiple Keys from Dictionary - GeeksforGeeks
July 12, 2025 - For example, consider a dictionary d = {'a': 1, 'b': 2, 'c': 3, 'd': 4} where we want to remove the keys 'b' and 'd', then the output will be {'a': 1, 'c': 3}. Let's explore different methods to remove multiple keys from a dictionary efficiently.
Is there a way to remove items/keys from a dict in a loop?
d = { ... } for k in list(d.keys()): d.pop(k, None) The important bit is the list(d.keys(). Instead of iterating over the dict itself, that creates a new separate list of keys and iterates over that. More on reddit.com

To delete a key regardless of whether it is in the dictionary, use the two-argument form of dict.pop():
my_dict.pop('key', None)
This will return my_dict[key] if key exists in the dictionary, and None otherwise. If the second parameter is not specified (i.e. my_dict.pop('key')) and key does not exist, a KeyError is raised.
To delete a key that is guaranteed to exist, you can also use
del my_dict['key']
This will raise a KeyError if the key is not in the dictionary.

Specifically to answer "is there a one line way of doing this?"
if 'key' in my_dict: del my_dict['key']
...well, you asked ;-)
You should consider, though, that this way of deleting an object from a dict is not atomic—it is possible that 'key' may be in my_dict during the if statement, but may be deleted before del is executed, in which case del will fail with a KeyError. Given this, it would be safest to either use dict.pop or something along the lines of
try:
del my_dict['key']
except KeyError:
pass
which, of course, is definitely not a one-liner.

my_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4} keys_to_remove = ['a', 'c'] new_dict = {k: v for k, v in my_dict.items() if k not in keys_to_remove} print(new_dict) # Output: {'b': 2, 'd': 4} Use pop() method in a for loop if performance is a major concern. Using del statement in a for loop is slightly slower than pop() method because you have to check for the existence of each key before deletion to avoid KeyError. Use list comprehension if you need to create a new dictionary excluding specific keys.
