Write to S3 in Parquet format in Python (or Typescript) without spark

Question

I want to write data to S3 in Parquet format from inside AWS Lambda job, without using Spark. Either Python or Typescript should work. If the function cane to append to the existing Parquet file that would be even more awesome. Thank you!
