You can even use generators in Python to perform this operation. The best method is the list comprehension technique. In this article, we learned to find the list of values from a given list of dictionaries by using several built-in functions such as append(), map(), lambda, operator and functools module etc and different examples to find the values on the basis of the given key. A dictionary can be defined using any variable name and then assigning different key-value pairs in curly braces. Data inside a dictionary can be of any type say, integer, string or a float value, etc. Each key-value pair maps the key to its associated value. A dictionary consists of a collection of key-value pairs. List3 = Python Dictionaryĭictionaries are Python's other built-in data type and it is also known as an associative array. The list is ordered, changeable, and allows duplicate values. Lists can be defined using any variable name and then assigning different values to the list in a square bracket. The list uses comma-separated values within square brackets to store data. Iterate over all the dicts in a list of dicts & check if a given value exists. Data inside the list can be of any type say, integer, string or a float value, or even a list type. Get all values in a list of dictionary & check if a given value exists. It is like a collection of arrays with different methodology. Python has a built-in data type called list. Let's first have a quick look over what is a list and a dictionary in Python. We will use some built-in functions, simple approaches, and some custom code as well to understand different ways. In this article, we will learn how to get a list of values from a dictionary in Python.
