Example 1: Using + operator
Output
[1, 'a', 3, 4, 5]
In this example, + operator is used to concatenate two lists.
Example 2: Using iterable unpacking operator *
Output
[1, 'a', 2, 3]
* operator allows unpacking inside the list or tuple.
Example 3: With unique values
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()
Output
[1, 2, 3, 1, 'a']
Using extend(), you can concatenate a list to another list as shown in example above.
