We can also use + operator to concatenate multiple lists to create a new list. Perhaps theoretically/under the hood that is correct however a major distinction between the two is the fact that lists accept mixed data types and mixed numeric types, on the other hand array requires a type-code restricting all elements to the determined type: Arrays are mutable in python, so they can be modified in place without copying the existing array contents. Note: When people say arrays in Python, more often than not, they are talking about Python lists.If that's the case, visit the Python list tutorial..
