Here is how to remove a key from dictionary in Python.


del my_dict["key1"] 

Output

  


Explanation

If you have a dictionary named my_dict and you want to remove the key "key1", you can use the del statement. This will remove the key-value pair from the dictionary, and the key will no longer be accessible. Keep in mind that the del statement will raise a KeyError if the key does not exist in the dictionary. You can avoid this error by using the dict.pop() method, which will remove the key-value pair from the dictionary and return the value associated with the key, or a default value if the key does not exist. Here's an example of using dict.pop() to remove a key from a dictionary:

my_value = my_dict.pop("key1", None)
In this case, the value associated with the "key1" key will be removed from the dictionary and stored in the my_value variable. If the "key1" key does not exist in the dictionary, the my_value variable will be set to None.

Alternatively, you can use the dict.popitem() method to remove a random key-value pair from the dictionary. This method returns a tuple containing the key and value of the removed item. Here's an example of using dict.popitem() to remove a key from a dictionary:
my_key, my_value = my_dict.popitem()
In this case, a random key-value pair will be removed from the dictionary, and the key will be stored in the my_key variable and the value will be stored in the my_value variable.
