Example 1: python remove element from list
myList.remove(item) # Removes first instance of "item" from myList
myList.pop(i) # Removes and returns item at myList[i]
Example 2: delete a value in list python
list.remove(element)
Example 3: how to delete an item from a list python
myList = ['Item', 'Item', 'Delete Me!', 'Item']
del myList[2] # myList now equals ['Item', 'Item', 'Item']
Example 4: python remove value from list
# Below are examples of 'remove', 'del', and 'pop'
# methods of removing from a python list
""" 'remove' removes the first matching value, not a specific index: """
>>> a = [0, 2, 3, 2]
>>> a.remove(2)
>>> a
[0, 3, 2]
""" 'del' removes the item at a specific index: """
>>> a = [9, 8, 7, 6]
>>> del a[1]
>>> a
[9, 7, 6]
""" 'pop' removes the item at a specific index and returns it. """
>>> a = [4, 3, 5]
>>> a.pop(1)
3
>>> a
[4, 5]
""" Their error modes are different too: """

Example 5: python how to remove elements from a list
# Basic syntax:
my_list.remove(element)
# Note, .remove(element) removes the first matching element it finds in
# the list.
# Example usage:
animals = ['cat', 'dog', 'rabbit', 'guinea pig', 'rabbit']
animals.remove('rabbit')
print(animals)
--> ['cat', 'dog', 'guinea pig', 'rabbit'] # Note only 1st instance of
# rabbit was removed from the list.
# Note, if you want to remove all instances of an element, convert the
# list to a set and back to a list, and then run .remove(element) E.g.:
animals = list(set['cat', 'dog', 'rabbit', 'guinea pig', 'rabbit']))
animals.remove('rabbit')
print(animals)
--> ['cat', 'dog', 'guinea pig']
Example 6: delete element from list value
>>> a=[1,2,3]
>>> a.remove(2)
>>> a
[1, 3]
>>> a=[1,2,3]
>>> del a[1]
>>> a
[1, 3]
>>> a= [1,2,3]
>>> a.pop(1)
2
>>> a
[1, 3]
>>>
