The childespy package allows you to access data in the childes-db from Python. This removes the need to write complex SQL queries in order to get the information you want from the database.
This package is a wrapper for the latest version of the childesr R package (https://github.com/langcog/childesr), so it requires the user to install R (>=3.6) on their machine. Instructions can be found here: https://www.r-project.org/.
childesr has R package dependencies, listed here, which childespy will automatically install.
This package is available through pip with pip3 install childespy and can be run with import childespy.
