Wherever you can use a comprehension, you can also use a for-loop. We will want to loop over the range of the length of one of the lists and access the items.

From this, we can see that the zip function method is significantly faster. It also happens to be more memory efficient since it only loads the data as it needs to! In this post, you learned three different ways two turn two Python lists into a dictionary.

Python lists and dictionaries are two structures used to store data. But what if you want to convert a list into a dictionary? You may want to do this if you want to assign a unique label to each value you have stored. This is only possible in a dictionary.

There are a few techniques and built-in functions you can use in Python to convert a list to a dictionary. This programming tutorial will discuss, with reference to examples, how to convert a list into a dictionary in Python. Lists and dictionaries are examples of Python collections. They allow you to store multiple similar values together in one data structure. The list data structure allows you to store data in a specific order. Here is an example of a Python list:.

Here is an example of a Python dictionary :. Get matched to a bootcamp today. The average bootcamp grad spent less than six months in career transition, from starting a bootcamp to finding their first job. Dictionaries are useful if you want to associate labels with each value. Lists are better if you are storing similar data, such as a list of prices or names, where you cannot label each value. You can convert a Python list to a dictionary using the dict.

The zip method is useful if you want to merge two lists into a dictionary. Say that we have a list of fruits that we want to turn into a dictionary. The value assigned to each fruit should be In stock :.

We could create this dictionary using the dict. This method accepts a list of keys that you want to turn into a dictionary. Optionally, you can specify a value you want to assign to every key. You can only specify one value to be assigned to every key. You cannot say that one key should have one value and another key should have a different value.

We first declare a Python variable called fruits which stores the names of the keys we want to use in our dictionary. We use dict. This method assigns the value of each key to be In stock.

Finally, we print the new dictionary to the console. If we did not specify the value In stock in our code, the default value for the keys in our dictionary would be None. We can also use a technique called dictionary comprehension to convert a Python list to a dictionary using the same values.

A dictionary comprehension is similar to a list comprehension in that both methods create a new value of their respective data types.
