How do I concatenate lists in Python in pure Python?

In Python, you can concatenate lists using several methods. Here are some of the most common approaches:

  • Using the `+` operator
  • Using the `extend()` method
  • Using list comprehension
  • Using the `itertools.chain()` method

Here's an example using the `+` operator:

list1 = [1, 2, 3] list2 = [4, 5, 6] result = list1 + list2 print(result) # Output: [1, 2, 3, 4, 5, 6]
