# Basic syntax:
first_list.append(second_list) # Append adds the second_list as an
# element to the first_list
first_list.extend(second_list) # Extend combines the elements of the
# first_list and the second_list
# Note, both append and extend modify the first_list in place
# Example usage for append:
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.append(second_list)
print(first_list)
--> [1, 2, 3, 4, 5, [6, 7, 8, 9]]
# Example usage for extend:
first_list = [1, 2, 3, 4, 5]
second_list = [6, 7, 8, 9]
first_list.extend(second_list)
print(first_list)
--> [1, 2, 3, 4, 5, 6, 7, 8, 9]
list_1 = ['w','h']
list_1.append('y') # you need no veribal to store list_1.append('y')
print(list_1) # ['w','h','y']
list_2 = ['a','r','e']
list_1.append(list_2) # This also donot need a veribal to store it
print(list_1) # ['w','h','y',['a','r','e']]
list_1.extend(list_2)
print(list_1) # ['w','h','y',['a','r','e'],'a','r','e']
# please like
# Add to List
my_list * 2 # [1, 2, '3', True, 1, 2, '3', True]
my_list + [100] # [1, 2, '3', True, 100] --> doesn't mutate original list, creates new one
my_list.append(100) # None --> Mutates original list to [1, 2, '3', True, 100] # Or: <list> += [<el>]
my_list.extend([100, 200]) # None --> Mutates original list to [1, 2, '3', True, 100, 200]
my_list.insert(2, '!!!') # None --> [1, 2, '!!!', '3', True] - Inserts item at index and moves the rest to the right.
' '.join(['Hello','There'])# 'Hello There' --> Joins elements using string as separator.
#.append() is a function that allows you to add values to a list
sampleList.append("Bob")
print ("Bob should appear in the list:", sampleList)
#The output will be:
Bob should appear in the list: ['Bob']
