This article shows different ways to concatenate two lists or other iterables in Python.Use a + b¶The simplest way is by just using the + operator to combine two lists:a = [1, 2] b = [3, 4] c = a + b # [1, 2, 3, 4] ...
In thisPython tutorial, I will explain how toconcatenate multiple lists in Pythonusing different methods with some illustrative examples.
