Precautions

Delete non-existent elements

When deleting an element that does not exist in the list, Python throws a ValueError exception.

>>> demo = [1, 3, 5]
>>> demo.remove(6)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ValueError: list.remove(x): x not in list

There are multiple elements in the list to be deleted

When there are more than one element to be deleted in the list, the remove() method deletes the first matching element.

demo = ["Pod", "ReplicationController", "Namespace", "ReplicationController"]
demo.remove("ReplicationController")
print(demo)
# outputs:
# ['Pod', 'Namespace', 'ReplicationController']
