In Python, both arrays and lists can be used to store collections of items. However, there are some key differences between the two:


FeatureArrayList
DefinitionA collection of items that are of the same data type and ordered.A collection of items that can be of different data types and ordered.
HomogeneityArrays are homogeneous, which means that they can only store elements of the same data type.Lists are heterogeneous, which means that they can store elements of different data types.
Memory AllocationArrays allocate memory in contiguous blocks of memory, which makes them more efficient for numerical operations.Lists allocate memory in non-contiguous blocks, which makes them less efficient for numerical operations.
Mutable vs. ImmutableArrays are mutable, which means that their elements can be changed after creation.Lists are mutable, which means that their elements can be changed after creation.
SizeArrays have a fixed size that is set at the time of creation.Lists can grow or shrink dynamically in size as elements are added or removed.
PerformanceArrays have faster performance compared to lists for numerical operations due to their contiguous memory allocation.Lists have slower performance compared to arrays for numerical operations due to their non-contiguous memory allocation.
Examplesarray('i', [1, 2, 3]), array('f', [1.0, 2.0, 3.0])[1, 'apple', True], ['red', 'green', 'blue']
