Question

I am trying to remove a dictionary from a list if it already exists but it doesn’t seem to be working. Can anyone see what I am doing wrong or advise me what I should be doing

new_dict = {'value': 'some value', 'key': 'someKey'}
if new_dict in my_list:
    my_list.remove(new_dict)

new_list is a list of dictionaries where new_dict is definitely in

Answer 1

If new_dict is “definitely” in my_list, then my_list.remove(new_dict) should do the trick (i.e., no need for the if new_dict in my_list, that just slows it down).
