Python program to concatenate two lists #python #shorts #coding

In this Python tutorial, we'll dive into how to concatenate two lists efficiently. Concatenating lists is a common operation in Python programming, and understanding different approaches to achieve this task can improve your coding skills. Whether you're a beginner or an experienced Python developer, mastering list manipulation techniques like concatenation is essential. Follow along with the code examples provided in the video to learn practical implementations of list concatenation in Python.
Python Program to Concatenate Two Lists
To understand this example, you should have the knowledge of the following Python programming topics:
Python List
Python List extend()
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, the + operator is used to concatenate two lists.

Example 2: 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 a list.

Example 3: Using extend()
list_1 = [1, 'a']
list_2 = [1, 2, 3]
print(list_2)
Output
[1, 2, 3, 1, 'a']
Using extend(), you can concatenate a list to another list as shown in the example above.
