You can use a list comprehension:
def remove_values_from_list(the_list, val):
return [value for value in the_list if value != val]
x = [1, 2, 3, 4, 2, 2, 3]
x = remove_values_from_list(x, 2)
print x
# [1, 3, 4, 3]

October 16, 2021how to remove all instances of an element in a list?
Deleting elements of a list while you are iterating over it is generally considered a bad idea in every language I personally know of. In Python, usually you should just build a new list. Experienced Python programmers would likely use what we call a 'list comprehension' to do this in a single line of code, but it looks like you aren't quite ready for that. This is perfectly fine! Just know that in Python, if you are iterating over a list using the range function and looking up list indices as you do so, chances are you are doing it the wrong way in 99.9% of cases. Python has different idioms. Here is a snippet of code, based on your own code but modified, that demonstrates how you might do this. This not how I would actually write it myself, but it is meant to demonstrate a few relevant Python idioms, be relateable to your code above, and hopefully to be tailored to your own personal skill level with Python. I don't think this is a homework assignment of yours, so it is basically giving you an answer for free, but due to its demonstrative nature I think it is probably okay in this case. my_list = [1, 2, 3, 2, 2, 4, 5, 6, 2, 2, 7, 8, 9, 2, 2, 2] unwanted_item = 2 new_list = [] for item in my_list: if item != unwanted_item: new_list.append(item) my_list = new_list print(my_list) More on reddit.com

There is no remove_all method or anything like that, but the best ways to accomplish this are with a list comprehension or filter.
Assuming that ls only contains other lists you can write the following to remove all occurrences of the empty list []:
List Comprehension
ls = [[1], [1, 2], [1, 2, 3], [], [2], [2, 3], [], [], [3]]
ls = [x for x in ls if x]
# now ls = [[1], [1, 2], [1, 2, 3], [2], [2, 3], [3]]
Filter
ls = [[1], [1, 2], [1, 2, 3], [], [2], [2, 3], [], [], [3]]
ls = list(filter(None, ls))
# now ls = [[1], [1, 2], [1, 2, 3], [2], [2, 3], [3]]
Generalizing for more than just the empty list
If you wanted to remove all occurrences of a given element elem (that is not the empty list) you can modify the above code as follows:
ls = [x for x in ls if x != elem]
##### or #####
ls = list(filter(lambda x: x != elem, ls))

A set object is an unordered collection of distinct hashable objects. Common uses include membership testing, removing duplicates from a sequence, and computing mathematical operations such as intersection, union, difference, and symmetric difference. (For other containers see the built-in dict, list, and tuple classes, and the collections module.)
