python list pop vs remove

>>> a = [9, 8, 7, 6]
>>> del a[1]
>>> a
[9, 7, 6]

Here is what the above code is Doing:
1. We create a list called a with four elements.
2. We delete the element at index 1.
3. We print the list.

The output is:

[9, 7, 6]

As you can see, the element at index 1 (8) is gone.

You can also delete a range of elements from a list. For example:

>>> a = [9, 8, 7, 6]
>>> del a[1:3]
>>> a
[9, 6]

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We delete the elements at indices 1 and 2.
3. We print the list.

The output is:

[9, 6]

As you can see, the elements at indices 1 and 2 (8 and 7) are gone.

You can also delete all the elements from a list. For example:

>>> a = [9, 8, 7, 6]
>>> del a[:]
>>> a
[]

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We delete all the elements from the list.
3. We print the list.

The output is:

[]

As you can see, the list is empty.

You can also delete the list itself. For example:

>>> a = [9, 8, 7, 6]
>>> del a
>>> a
Traceback (most recent call last):
File ““, line 1, in
NameError: name ‘a’ is not defined

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We delete the list.
3. We try to print the list.

The output is:

Traceback (most recent call last):
File ““, line 1, in
NameError: name ‘a’ is not defined

As you can see, the list is gone and we get an error when we try to print it.

You can also delete an element from a list by using the remove() method. For example:

>>> a = [9, 8, 7, 6]
>>> a.remove(8)
>>> a
[9, 7, 6]

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We remove the element 8 from the list.
3. We print the list.

The output is:

[9, 7, 6]

As you can see, the element 8 is gone.

You can also delete an element from a list by using the pop() method. For example:

>>> a = [9, 8, 7, 6]
>>> a.pop(1)
8
>>> a
[9, 7, 6]

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We remove the element at index 1 from the list and print it.
3. We print the list.

The output is:

8
[9, 7, 6]

As you can see, the element at index 1 (8) is removed from the list and printed.

You can also delete an element from a list by using the pop() method with no arguments. For example:

>>> a = [9, 8, 7, 6]
>>> a.pop()
6
>>> a
[9, 8, 7]

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We remove the last element from the list and print it.
3. We print the list.

The output is:

6
[9, 8, 7]

As you can see, the last element (6) is removed from the list and printed.

You can also delete an element from a list by using the del statement with an index. For example:

>>> a = [9, 8, 7, 6]
>>> del a[1]
>>> a
[9, 7, 6]

Here’s what the above code is doing:
1. We create a list called a with four elements.
2. We delete the element at index 1.
3. We print the list.

The output is:

[9, 7, 6
