We then use the izip() function to iterate over the lists. We have declared two lists, list01 and list02, with some data values. It returns the elements of both lists mapped together according to their index. It then zips or maps the elements of both lists together and returns an iterator object. It iterates over the lists until the smallest of them gets exhausted. The izip() function also expects a container such as a list or string as input. To use a version before Python 3.0, we use the izip() function instead of the zip() function to iterate over multiple lists. Use the izip() Function to Iterate Over Two Lists in Python This is how we can iterate over two lists using the zip() function.

So, the expected output is 1, x and 2, y. It maps the elements of both the lists in a clubbed or tuple format to return an iterator object. The zip() function then iterates over the two lists in parallel only 2 times the length(list02)=2. We pass the lists list01 and list02 as input to the zip() function. We have two lists for iteration indicated in the code. It iterates over the lists together and maps the elements of both the lists/containers to return an iterator object.

The zip function accepts multiple lists, strings, etc., as input. Python zip function enables us to iterate over two or more lists by running until the smaller list gets exhausted. Use the zip() Function to Iterate Over Two Lists in Python Well, having recalled the iteration of a single list, let us now understand different ways through which we can iterate two Python lists. Isn’t that simple? And, if we have more than one list to iterate in parallel?! The stop index is set as 4, equivalent to the list length, so that the range() function iterates the sequence until the last element and displays it. Here, we have passed the start index to the function as 0 so that it starts to get the sequence of elements from the list right from position 0, i.e., the first element. Output: Iteration through a single list: 10 Print('Iteration through a single list:', lst) We declare a list with some arbitrary values and then loop in the list using any in-built function such as range().

The step index is an optional parameter that allows us to include patterns such as increments in the iteration of the sequence of elements in the list.Ĭonsider the example below.

The stop index determines the position or integer where the iteration of the sequence of elements should stop.

The start index is where the range() function starts to iterate and get the numbers or elements.

Reverse a List using One Line Python Code #shorts #coding #programming It accepts start, stop, and step as input. The range(start, stop, step) function enables us to get a sequence of numbers from a defined range of values. We can iterate over a single Python list using a for loop or a range() function. This article will unveil the different ways to iterate over two lists in Python with some demonstrations. Iterating a single data structure like a list in Python is common, but what if we come across a scenario that expects us to iterate over two/multiple lists together? While parsing the data stored in data structures such as dictionary, tuple, list, we come across iteration to move over the data sequence stored in it.
