If you do not have pandas already installed in and imported into your Python environment, run the lines of code below in your preferred Python programming IDE in order to install and import list of dictionaries to dataframe otherwise, you can skip to the next section:. We will create a sample list of dictionaries using identical keys with differing values.

Working with data in Python often involves using Pandas, a powerful library that provides data manipulation and analysis tools. One common task is converting a DataFrame into a list of dictionaries, which can be useful for various data processing operations. In this blog post, we will explore different approaches to convert a DataFrame to a list of dictionaries in Python. To follow along with the examples in this blog post, you should have a basic understanding of Python and be familiar with the Pandas library. Make sure you have the necessary libraries installed, including Pandas.

When working with Pandas dataframes , you may sometimes encounter a column that contains a list of Python dictionaries or JSON objects. To get started open a new Jupyter notebook and import the Pandas package. We can now use the pd. As you can see, the variants column contains a list of Python dictionaries or JSON objects and is not easy to read or work with. The function will take the df dataframe as an argument and return a new dataframe with the variants column converted into a new dataframe. The function first creates a list called rows that will hold each row of data we want to add to the dataframe. DataFrame function to create a new dataframe from the rows list. Now we can use our reusable function and pass it the df dataframe and the name of the column that contains the list of dictionaries or JSON objects. We get back a nice neat dataframe containing only the contents of the variants column. Picture by Pixabay, Pexels. Data Science Pandas.

Dict is a type in Python to hold key-value pairs. Key is used as a column name and value is used for column value when we convert dict to DataFrame. When a key is not found for some dicts and it exists on other dicts, it creates a DataFrame with NaN for non-existing keys.
