The length of the resulting tuples will always equal the number of iterables you pass as arguments. You can refer to the below screenshot to see the output for python zip three lists.

In python zip for loop, we have multiple iterable objects that can be handled by using zip , and the for loop is used to iterate.

Python zip list of lists defines three different lists with the same number of items and passes those lists to the zip method, which will return the tuple iterator and then convert it into the list using the list method.

It can be helpful to think of the zip function as combining two or more lists or other iterable objects into an object containing ordered tuples from the lists. The reason for this is that the zip function actually returns a zip object. We can confirm this by checking the type of this:. The zip function takes in any number of iterable objects and will zip them together.

However, something to keep in mind: the built-in zip function will max out at the length of the shortest iterable provided. Because of this, if one list contains 5 elements and another list contains a million — the resulting zip object will just contain 5 items.

The result of calling zip on the iterables is displayed on the right. As a first example, let's pick two lists L1 and L2 that contain 5 items each. Let's call the zip function and pass in L1 and L2 as arguments. If you go back to the documentation, the second item in the numbered list reads: "The iterator stops when the shortest input iterable is exhausted.

Unlike working with the range object, using zip doesn't throw errors when all iterables are of potentially different lengths. Let's verify this as shown below. We now see that the output list only contains 4 tuples and the item 5 from L1 has not been used. So far so good! Let's go ahead and verify this. Observe how we get 1-tuples when we pass in only L1 in the code snippet below:. When we call the zip function with no arguments, we get an empty list, as shown below:.

Let's now create a more intuitive example. The code snippet below shows how we can use zip to zip together 3 lists and perform meaningful operations.

Given a list of fruits, their prices and the quantities that you purchased, the total amount spent on each item is printed out. Now we understand how the zip function works, and we know its limitation that the iterator stops when the shortest iterable is exhausted. Let's now try out an earlier example of L2 containing one item less than L1.
