Example 1: delete element of a list from another list python

l1 = ["a", "b", "c", "d", "e", "f"]
l2 = ["b", "c", "e"]

l1 = [elt for elt in l1 if elt not in l2]
# l1 = ['a', 'd', 'f']

Example 2: python remove element from list

myList.pop(i) # Removes and returns item at myList[i]

Example 3: 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']

print(l)
# [1, 2, 3, 4, 5, 6, 7, 8, 9]

# [1, 2, 3, 4, 5, 6, 7, 8]
