Question: How do Python arrays and lists differ from each other?
Answer:

The difference between Python array and Python list is as follows:

ArraysLists
The array is defined as a linear structure that is used to store only homogeneous data.The list is used to store arbitrary and heterogeneous data
Since array stores only a similar type of data so it occupies less amount of memory when compared to the list.List stores different types of data so it requires a huge amount of memory 
The length of the array is fixed at the time of designing and no more elements can be added in the middle.The length of the list is no fixed, and adding items in the middle is possible in lists.
