python list remove with index code example

Example 1: how to remove an element in a list by index python

list = [0, 1, 2, 3, 4, 5]

print(list)
# [0, 1, 2, 3, 4, 5]

del list[0]
print(list)
# [1, 2, 3, 4, 5]
      
del list[-2]
print(list)
# [1, 2, 3, 5]
      
del list[0:2]
print(list)
# [3, 5]

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 list remove at index

a = ['a', 'b', 'c', 'd']
a.pop(1)

# now a is ['a', 'c', 'd']
