Answer 1

You can use pyarrow to read Parquet files with Python 2.7, see https://arrow.apache.org/docs/python/parquet.html Note that there are no Python 2.7 wheels available for Windows. You either need to use conda there or switch to Linux / OSX.

Read Parquet files:

import pyarrow.parquet as pq
table = pq.read_table("file.parquet")
# Optionally convert to Pandas DataFrame
df = table.to_pandas()

Write Parquet files:

import pyarrow as pa
import pyarrow.parquet as pq

# If your input data is a Pandas DataFrame, we need to convert it to an Arrow table first.
table = pa.Table.from_pandas(df)
pq.write_table(table, "filename.parquet")
