title: Get schema of parquet file in Python
body: <p>Is there any python library that can be used to just get the schema of a parquet file?</p>
  <p>Currently we are loading the parquet file into dataframe in Spark and getting schema from the dataframe to display in some UI of the application. But initializing spark-context and loading data frame and getting the schema from dataframe is time consuming activity. So looking for an alternative way to just get the schema.</p>
