Example 1: how to combine two lists in python
listone = [1,2,3]
listtwo = [4,5,6]
joinedlist = listone + listtwo
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: add two list in python
list1 = ["a", "b" , "c"]
list2 = [1, 2, 3]
list1.extend(list2)
print(list1)
Example 4: join lists python
first_list = ["1", "2"]
second_list = ["3", "4"]
# Multiple ways to do this:
first_list += second_list
first_list = first_list + second_list
first_list.extend(second_list)
Example 5: python add elements of two lists together
list1 = [1, 2, 3]
list2 = [4, 5, 6]
sum_list = []
for (item1, item2) in zip(list1, list2):
sum_list.append(item1 + item2)
print(sum_list)
Example 6: merge two lists
# Makes list1 longer by appending the elements of list2 at the end.
list1.extend(list2)
