In this example, we use an Iterator object to iterate over a List and use the next() method inside a while loop to print each element of the List one by one:Open Compiler import java.util.ArrayList; import java.util.Iterator; public class iterateOverList { public static void main(String...
Another approach is that - Iterate over the list using for ... in loop and insert each element at the 0th index using the list.insert() method. When a new element will be added at the 0th index the previous element will be shifted to the next position. In this way, we will get ...

Python Code: # Define a function 'pairwise' that iterates over all pairs of consecutive items in a listdefpairwise(l1):# Create an empty list 'temp' to store the pairstemp=[]# Iterate through the list elements up to the second-to-last elementforiinrange(len(l1)-1):# Get the curr...
To iterate through a list in Python, the most straightforward method is using aforloop. The syntax is simple:for item in list_name:, whereitemrepresents each element in the list, andlist_nameis the list you’re iterating over. For example, if you have a list of city names likecities ...
Run Code Output 1 a 2 b 3 c 1 a 2 b 3 c 4 None Using the zip_longest() method of itertools module, you can iterate through two parallel lists at the same time. The method lets the loop run until the longest list stops. Also Read: Python Program to Concatenate Two Lists Share...
