Pandas AWS - AWS made easy for data scientists

Pandas AWS makes it super easy to use a pandas.DataFrame along with AWS services.

Working with S3

First create an S3 client to be used later and define a bucket

from pandas_aws import get_client

s3 = get_client('s3')
MY_BUCKET= 'pandas-aws-bucket'

Example 1: get a DataFrame from a parquet file stored in S3

from pandas_aws.s3 import get_df

df_from_parquet_file = get_df(s3, MY_BUCKET, 'my_parquet_file_path', format='parquet')

Example 2: get a DataFrame from multiple CSV files (with same schema) stored in S3

from pandas_aws.s3 import get_df_from_keys

df_from_list = get_df_from_keys(s3, MY_BUCKET, prefix='my-folder', suffix='.csv')

Example 3: put a DataFrame into S3 using an xlsx (Excel) file format

from pandas_aws.s3 import put_df

put_df(s3, my_dataframe, MY_BUCKET, 'target_file_path', format='xlsx')

Example 4: put a DataFrame into S3 using multi parts upload

from pandas_aws.s3 import put_df

put_df(s3, my_dataframe, MY_BUCKET, 'target_file_path', format='csv', compression='gzip', parts=8)

Installing pandas-aws

Pip installation

You can use pip to download the package

pip install pandas-aws

Contributing to pandas-aws

Git clone

We use the develop brand as the release branch, thus git clone the repository and git checkout develop in order to get the latest version in development.

git clone [e-mail]:FlorentPajot/pandas-aws.git

Preparing your environment

Pandas AWS uses poetry to manage dependencies. Thus, poetry is required:

curl -SSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python

Create a separate Python environment, for example using pyenv along with pyenv-virtualenv and Python 3.7.7:

pyenv install 3.7.7
pyenv virtualenv 3.7.7 pandas-aws
pyenv activate pandas-aws

Check your environment using:

which python
// should show something like .pyenv/shims/python
python -V
// should show python 3.7.7 (or any other version you selected)
pip list
// should show barely nothing except pip and setuptools

In cas your encounter a problem, check Pyenv documentation.

Then install dependencies with poetry after your git clone from the project repository:

poetry install
