Dataprep: Data Preparation in Python

---

Documentation | Forum | Mail List

Dataprep lets you prepare your data using a single library with a few lines of code.

Currently, you can use dataprep to:

• Collect data from common data sources (through dataprep.connector)
• Do your exploratory data analysis (through dataprep.eda)
• ...more modules are coming

Examples & Usages

The following examples can give you an impression of what dataprep can do:

• Documentation: Connector
• Documentation: EDA
• EDA Case Study: Titanic
• EDA Case Study: House Price

EDA

There are common tasks during the exploratory data analysis stage, like a quick look at the columnar distribution, or understanding the correlations between columns.

The EDA module categorizes these EDA tasks into functions helping you finish EDA tasks with a single function call.

• Want to understand the distributions for each DataFrame column? Use plot.

• Want to understand the correlation between columns? Use plot_correlation.

• Or, if you want to understand the impact of the missing values for each column, use plot_missing.

You can drill down to get more information by given plot, plot_correlation and plot_missing a column name.: E.g. for plot_missing

    for numerical column usingplot:

    for categorical column usingplot:

Connector

Connector provides a simple way to collect data from different websites, offering several benefits:

• A unified API: you can fetch data using one or two lines of code to get data from many websites.
• Auto Pagination: it automatically does the pagination for you so that you can specify the desired count of the returned results without even considering the count-per-request restriction from the API.
• Smart API request strategy: it can issue API requests in parallel while respecting the rate limit policy.

In the following examples, you can download the Yelp business search result into a pandas DataFrame, using only two lines of code, without taking deep looking into the Yelp documentation! More examples can be found here: Examples
