How do I concatenate lists in Python in an async application?

In Python, you can concatenate lists using various methods. This is particularly useful in asynchronous applications where you may need to gather and combine results from different asynchronous calls. Below are some common methods to concatenate lists.

Keywords: Python, concatenate lists, async application, list methods
Description: This guide explains various methods of list concatenation in Python, especially in the context of asynchronous programming.
# Using the + operator list1 = [1, 2, 3] list2 = [4, 5, 6] combined_list = list1 + list2 print(combined_list) # Output: [1, 2, 3, 4, 5, 6] # Using the extend() method list1 = [1, 2, 3] list2 = [4, 5, 6] list1.extend(list2) print(list1) # Output: [1, 2, 3, 4, 5, 6] # Using the itertools.chain() method import itertools list1 = [1, 2, 3] list2 = [4, 5, 6] combined_list = list(itertools.chain(list1, list2)) print(combined_list) # Output: [1, 2, 3, 4, 5, 6] # Using List Comprehension list1 = [1, 2, 3] list2 = [4, 5, 6] combined_list = [item for lst in [list1, list2] for item in lst] print(combined_list) # Output: [1, 2, 3, 4, 5, 6]
