Example 1: add all items in list to another list python
a = [1]
b = [2,3]
a.extend(b)
print(a)
------ OR -------
a += b
Example 2: 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 3: python add all values of another list
a = [1, 2, 3]
b = [4, 5, 6]
a += b
# another way: a.extend(b)
Example 4: 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)
