How to remove a key-value pair from a dictionary when the key is unknown in Python

Removing a key-value pair from a dictionary when the key is unknown results in a new dictionary without the specified key-value pair.

Solution for How to remove a key-value pair from a dictionary when the key is unknown in Python : You can use dict.items() to remove a key-value pair from a dictionary when the key is unknown Use dict.items() to get a list of key, value tuples from the dictionary dict. Use a for-loop to iterate through each key, value pair in the list. At each iteration, use an if-statement to check if value equals the value to remove. If it doesn’t, use dict[key] = value to add the current key, value pair to a new dictionary dict.

Use a dictionary comprehension for a more compact implementation.

a_dictionary = {"a": 1, "b" : 2, "c": 3}
