The Spark Python API (PySpark) exposes the Spark programming model to Python.

Spark’s Python API #

Key Differences in the Python API #

There are a few key differences between the Python and Scala APIs:

  • Python is dynamically typed, so RDDs can hold objects of multiple types.
  • PySpark does not yet support a few API calls, such as lookup and non-text input files, though these will be added in future releases.

IPython Configuration #
