Most of the time you are adding elements into a list, or set, or a dictionary. However, there can also be cases when you just need to remove elements. Maybe a particular element, or even all elements at once.
If that is the case, then there is a quick method in Python that you can use to do that.
Let us first start with removing all the elements from a list.
Let us assume that we have the following list:
Now, all we have to do is call the method clear():
If we check, now there is no element left in the list:
The same applies to both sets and dictionaries.
For the sake of illustration, let us take a set with 3 elements:
Now, to remove all the elements in there, we can call the same function as earlier:
If we check, there are no remaining elements in the set:
Similarly, let us take a dictionary:
We call the same method again:
As you can probably tell, no elements are left in the dictionary anymore:
Yes, I know, this is quite straightforward and not that complicated, but wait. Why such an easy task should be complicated in the first place?
I hope you find this helpful.
