Python is known to be the language that gives you the ability to write a few lines of code that can do a lot of things.
Just a few Python lines can be enough to pull data from an API that you can then also visualize in a fancy diagram.
Or even a single line of code can be enough for you to do plenty of things.
There are a lot of Python one-liners online that you can find.
In this article, we are going to see how to iterate through elements of a dictionary in a single line.
Before that, let’s start with iterating through elements in a list, as it can keep things rolling and seems less intimidating at first sight.
Let’s say that we have a list:
Now let’s say that we want to get only the even numbers that are on this list in a single line. Here’s how we can do that:
As you can see, it’s not that hard.
Now let’s say that we have a dictionary like the following:
Let’s say that we want to get only the elements that have odd values.
To do that, we need to first recall that an element in a dictionary contains a key and a value and we are going to have a condition based on the value of each element in the dictionary. So we are going to get both keys and values of a dictionary.
To iterate through the dictionary, we will use the method items().
Let’s see the whole example:
We could of course get only the keys from the dictionary:
Similarly, we can get only the values:
That’s basically it. It’s that simple.
That brings us to the end of this article.
I hope you find it useful.
