List Comprehension: Elegant way to create new List. Suppose, we need to compute the transpose of a matrix that requires nested for loop. Example. Both the while loop and range-of-len methods rely on looping over indexes. But sometimes lists can also contain lists within them. So when the control flows from the outer loop to the inner loop it returns back to the outer-loop only when the inner loops are completed. Let’s glance at 11 ways to Iterate Through List in Python which we are learning today. In this article we will see how to use list comprehension to create and use nested lists in python.
