It is possible to nest aforloop into another loop. for_loop_nested.py #!/usr/bin/python nums = [[1, 2, 3], [4, 5, 6], [7, 8, 9]] for i in nums: for e in i: print(e, end=' ') print() We have a two-dimensional list of integers. We loop over the elements with ...
Aloopis a sequence of instructions that is continually repeated until a certain condition is reached. For instance, we have a collection of items and we create a loop to go through all elements of the collection. In Python, we can loop over list elements with for and while statements, and...
Loop through sequences: used for iterating over lists, strings, tuples, dictionaries, etc., and perform various operations on it, based on the conditions specified by the user. Example: Calculate the average of list of numbers numbers = [10, 20, 30, 40, 50] # definite iteration # run...
In this example, you use two nested loops. Together, they create a two-dimensional multiplication table. First, you loop over the numbers from one up to and including ten. These represent the rows in the table, and you can see those numbers at the beginning of each row. In the inner ...

Nested loops are typically used for working with multidimensional data structures, such as printing two-dimensional arrays, iterating a list that contains a nested list. A nested loop is a part of acontrol flow statementthat helps you to understand thebasics of Python. ...
Iterating through Python Lists Iterating is quite simple in lists. We can just use Python for loop to iterate, as shown below: Python 1 2 3 4 5 list1 = [1,2,3,4,5] for element in list1: print(element) Output: 1 2 3 4 5 List comprehension in Python List comprehension has a...
What is the purpose of the pop() method in Python lists? Explain how to use a loop to iterate through all items in a list. What does the count() method do in a list? How can you convert a list into a tuple?Python- Multi dimensional List » Matrix Multiplication without using built...
