Example 1: Using + operator
list_1 = [1, 'a']
list_2 = [3, 4, 5]
list_joined = list_1 + list_2
print(list_joined)
Output
[1, 'a', 3, 4, 5]
In this example, + operator is used to concatenate two lists.
Example 2: Using iterable unpacking operator *
list_1 = [1, 'a']
list_2 = range(2, 4)
list_joined = [*list_1, *list_2]
print(list_joined)
Output
[1, 'a', 2, 3]
* operator allows unpacking inside the list or tuple.
Example 3: With unique values
list_1 = [1, 'a']
list_2 = [1, 2, 3]
list_joined = list(set(list_1 + list_2))
print(list_joined)
Output
[1, 2, 3, 'a']
If you want the unique items from a concatenated list, you can use list() and set(). set() selects the unique values and list() converts the set into list.
Example 4: Using extend()
list_1 = [1, 'a']
list_2 = [1, 2, 3]
list_2.extend(list_1)
print(list_2)
Output
[1, 2, 3, 1, 'a']
Using extend(), you can concatenate a list to another list as shown in example above.
