python .remove function code example

Example 1: python delete from list

l = list[1, 2, 3, 4]
l.pop(0) #remove item by index
l.remove(3)#remove item by value
#also buth of the methods returns the item

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]
