This section covers different methods to concatenate lists in Python, helping you combine multiple lists efficiently.

# Using the + operator list1 = [1, 2, 3] list2 = [4, 5, 6] concatenated_list = list1 + list2 print(concatenated_list) # Output: [1, 2, 3, 4, 5, 6] # Using the extend() method list3 = [1, 2, 3] list4 = [4, 5, 6] list3.extend(list4) print(list3) # Output: [1, 2, 3, 4, 5, 6] # Using list comprehension list5 = [1, 2, 3] list6 = [4, 5, 6] concatenated_list_comp = [item for sublist in [list5, list6] for item in sublist] print(concatenated_list_comp) # Output: [1, 2, 3, 4, 5, 6]
