While lists aren’t the most efficient data structure if you’ll be doing lots of deleting from the middle, there are definitely good ways to accomplish the task. The built-in `remove()`

method should be your first option. Let’s go over some examples.

## Remove element in Python list by value π

```
primes = [2, 3, 5, 5, 7, 11]
primes.remove(5)
print(primes)
# [2, 3, 5, 7, 11]
primes.remove(5)
# [2, 3, 7, 11]
primes.remove(5)
# careful, this will throw an error
# ValueError: list.remove(x): x not in list
```

If you want to safely remove items, and you aren’t sure if they exist in the list or not, you can either catch the error:

```
try:
primes.remove(5)
except Exception as e:
print("not in list")
```

Or, you can check for existence first:

```
if 5 in primes:
primes.remove(5)
```

## Remove an element in Python list by index π

The `del`

statement is a built-in keyword that allows you to remove items from lists. The simplest example deletes the item at a given index.

```
primes = [2, 3, 5, 5, 7, 11]
# delete the second item
del primes[1]
print(primes)
# [2, 5, 5, 7, 11]
```

Again, you need to be careful. If the index doesn’t exist an error will be raised.

```
primes = [2, 3, 5, 5, 7, 11]
# delete the eleventh item
del primes[10]
```

`IndexError: list assignment index out of range`

```
if len(primes) >= 10:
del primes[10]
```

## Come to the dark side

Regards and sorry for the interruption, Lane here! I built Boot.dev to give you a place to learn back-end development the...hard way? I mean easy? Maybe the "heasy" way? I don't know.

It's hard because you will have to write code... like a metric ton of code. It's easy because my courses have a built-in game that's pretty darn fun. Give it a try.

## Remove multiple of items from a python list π

```
primes = [2, 3, 5, 5, 7, 11]
# deleting items from 2nd to 4th
del primes[1:4]
print(primes)
# [2, 7, 11]
```

## Remove item by index and return it π

The `.pop()`

method removes an item from a list by index and returns that item.

```
primes = [2, 3, 5, 7]
# pop the second element
popped = primes.pop(1)
print("popped:", popped)
# 3
print("list:", primes)
# [2, 5, 7]
```

If you don’t pass an index parameter to `pop()`

it will default to `-1`

and remove the last element from the list. Just like the other methods, if you pass in a number too large, you’ll get the following error.

`IndexError: pop index out of range`
