.extend() py code example

Example 1: what does .extend do in python

# Difference between .append() and .extend() in python
# .extend explained below :)

list = ['hello', 'bro'] 
my_list.append('append') 

print (my_list)
>>> ['geeks', 'for', 'geeks']

my_list.append ([6, 0, 4, 1])

print (my_list)
>>> ['geeks', 'for', 'geeks', [6, 0, 4, 1]]

# For list.extend, each element of an iterable gets appended 
# to my_list

my_list = ['geeks', 'for'] 
another_list = [6, 0, 4, 1] 
my_list.extend(another_list) 

print (my_list)
>>> ['geeks', 'for', 6, 0, 4, 1]

# NOTE: A string is an iterable, so if you extend
# a list with a string, you’ll append each character
# as you iterate over the string.

my_list = ['geeks', 'for', 6, 0, 4, 1] 
my_list.extend('geeks') 

print (my_list)
>>>['geeks', 'for', 6, 0, 4, 1, 'g', 'e', 'e', 'k', 's']
