Example 1: delete a value in list python
list.remove(element)
Example 2: 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: """
>>> a = [4, 5, 6]
>>> a.remove(7)

ValueError: list.remove(x): x not in list
>>> del a[7]

Example 3: remove element from list python
# animals list
animals = ['cat', 'dog', 'rabbit', 'guinea pig']
# 'rabbit' is removed
animals.remove('rabbit')
# Updated animals List
print('Updated animals list: ', animals)
Example 4: remove item from list python
l = list[1, 2, 3, 4]
for i in range(len(list)):
l.pop(i) # OR "l.remove(i)"
Example 5: 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]
>>>
Example 6: del vs remove python
A = [1,2,3,4]
del(A[1])
# A: [1,3,4]
B = {9,8,7,6}
B.remove("8")
# B: {9,7,6}
