python append list to another list code example

Example 1: python append list to another list

my_list = ['a','b']  
my_list.append('c') 
print(my_list)      # ['a','b','c']

other_list = [1,2] 
my_list.append(other_list) 
print(my_list)      # ['a','b','c',[1,2]]

my_list.extend(other_list) 
print(my_list)      # ['a','b','c',[1,2],1,2]

Example 2: add all items in list to another list python

a = [1]
b = [2,3]
a.extend(b)
print(a)

------  OR  -------
a += b

Example 3: python how to add one list to another list

# Basic syntax:
first_list.append(second_list) # Append adds the 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]

Example 4: python add all values of another list

a = [1, 2, 3]
b = [4, 5, 6]
a += b
# another way: a.extend(b)

Example 5: append a list to another list as element

a = ['Jon', 'janni', 'Jannardhan']
b = ['28', '29', '30']
a.append(b)
print(a)
a.pop()
a.extend(b)
print(a)
