How to Iterate Over Every Nth Element in String in Loop Using Python

Guide Kit

Iterating through a list, tuple, or string of elements is possible with a loop in Python, which is a control flow statement. There are several types of loops in Python, including:

for loops: These loops iterate over a sequence of items, such as a list or tuple, and perform a specific operation for each item.
while loops: These loops continue to execute a block of code as long as a given condition is true.

The loops are very useful in Python, and you can use them to perform repetitive tasks, iterate over sequences, and automate processes.

To iterate over every nth element in a string in a loop, you can use a for loop with the “range()” function and string slicing. To obtain the index and value of each nth element, you may alternatively use the “enumerate()” function.

range function: This function can generate a sequence of numbers and iterate over them using a for loop.
enumerate function: In Python, you can iterate over a sequence and get both the index and the value of each element by using the enumerate() function.

For more information about iterating over every nth element in a string in loop-Python, refer to the code below.
