To get a list of tuples, use list(zip(foo, bar)). And to zip until both iterators are exhausted, you would use itertools.zip_longest. In Python 2, zip returns a list of tuples. This is fine when foo and bar are not massive.

Nov 22, 2024 · A simple approach to iterate over two lists is by using zip() function in Python. we can combine two lists and iterate over them in parallel. It creates pairs of elements by matching elements from each list at the same index.

Nov 30, 2022 · In this article, we’ll learn how to best loop over multiple lists in Python. We will start with a simple for loop, learn how to iterate over multiple lists “manually”, then explore the usefulness of the zip and zip_longest functions.

Mar 29, 2018 · I'm trying to loop through 2 lists and combine the results and write that to a file, however I could find a method to do this yet. hosts = ['host1', 'host2', 'host3'] ips = ['ip1', 'ip2', 'ip3'] filename = 'devicelist.txt' with open(filename, 'w') as out_file: for i in ips: for h in hosts: out_file.write(h + ' - ' + i + '\n')

Mar 6, 2023 · Given two lists, write a Python program to merge the given lists in an alternative fashion, provided that the two lists are of equal length. Examples: Input : lst1 = [1, 2, 3] lst2 = ['a', 'b', 'c'] Output : [1, 'a', 2, 'b', 3, 'c'] Input : lst1 = ['name', 'alice', 'bob'] lst2 = ['marks', 87, 56] Ou

May 9, 2014 · I need to loop through 2 lists. I want to loop through until the first list is complete; whereas the second list should repeat itself until the first list is complete. I want to input a list of databases and a list of streams.

Dec 19, 2024 · Let's explore a few methods to use list comprehension with two lists. One of the most common tasks is to apply conditions to two lists. We can use list comprehension and zip () to filter or modify elements based on conditions. Explanation: zip(a, …

Jun 19, 2023 · This concise, example-based article will walk you through some different ways to iterate over 2 Python lists in parallel. Without more delays, let’s get started.

Feb 9, 2025 · We can iterate over a single Python list using a for loop or a range() function. The range(start, stop, step) function enables us to get a sequence of numbers from a defined range of values. It accepts start , stop , and step as input.
