To read a .parquet file with Python, the pandas library is your friend. In fact, pandas provides a convenient way to read and write data in a variety of formats (you might be familiar with CSV or XLS[X] files), including Parquet.
I create a small example to show you:
  import pandas as pd
  ## read the Parquet file into a DataFrame 
  df = pd.read_parquet('example.parquet')
  ## display the DataFrame
  print(df)
Note: The file is assumed to be in the current working directory with the name example.parquet.
- you can change the name of the file from 
exampletodfordata_source - you can change the directory to save this file by adding 
folder/subfolder/example.parquet - you can also change the directory using 
os
