Example 1: python list .remove
a = [10, 20, 30, 20]
a.remove(20)
# a = [10, 30, 20]
# removed first instance of argument
Example 2: 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 3: python remove
# the list.remove(object) method takes one argument
# the object or element value you want to remove from the list
# it removes the first coccurence from the list
generic_list = [1, 2, 2, 2, 3, 3, 4, 5, 5, 5, 6, 8, 8, 8]
generic_list.remove(1)
# The Generic list will now be:
# [2, 2, 2, 3, 3, 4, 5, 5, 5, 6, 8, 8, 8]
Example 4: python remove from array
arr = []
arr.remove(value)
Example 5: remove in list python
# animals list
animals = ['cat', 'dog', 'rabbit', 'guinea pig']
# 'rabbit' is removed
animals.remove('rabbit')
# Updated animals List
print('Updated animals list: ', animals)
