In this example, we loop through the list of integers. We use an if statement to check if the number is even or odd, and we print the corresponding message based on the condition.Video, Further Resources & Summ

tuple -> () # tuple is a like a list but you cannot change the values in a tuple once it's defined. Tuples are good for storing information whose elements shouldn't be changed throughout the life of a program. Deque deque is preferred over a list in the cases where we need quicker...
Python range is one of thebuilt-in functions. When you want the for loop to run for a specific number of times, or you need to specify a range of objects to print out, the range function works really well. When working withrange(), you can pass between 1 and 3 integer arguments to...
Iterate Dictionary using for loop What is for loop in Python In Python, theforloop is used to iterate over a sequence such as alist, string,tuple, other iterable objects such asrange. With the help offorloop, we can iterate over each item present in the sequence and executes the same ...
Method 1: Using a for Loop Theforloop is one of the simplest and most common ways to iterate through a list in Python. Here’s the basic syntax: for item in list_name: # Do something with item Example: Let’s say we have a list of city names, and we want to print each city:...
When you’re working with iterables of string objects, you might be interested in transforming all the objects using some kind of transformation function. Python’s map() can be your ally in these situations. The following sections will walk you through some examples of how to use map() to...

The collections module provides a deque object that is like a list with faster appends and pops from the left side but slower lookups in the middle. These objects are well suited for implementing queues and breadth first tree searches:
