Here is how to delete an element from a dictionary in Python.

my_dict = {'a': 1, 'b': 2, 'c': 3}
del my_dict['b']
print(my_dict) 

{'a': 1, 'c': 3}

You can delete an element from a dictionary in Python by using the del statement and specifying the key of the element you want to remove.

The above code will remove the key-value pair where the key is 'b'.

Alternatively, you can also use the pop() method with the key of the element as an argument. For example:

my_dict = {'a': 1, 'b': 2, 'c': 3}
my_dict.pop('b')
