s3-reader 0.2.3

Python library to read S3 file as local file.

s3-reader

Python library to read S3 file as local file.

Requirement

• Python 3.9, 3.10, 3.11

Installation

$ pip install s3-reader

Usage

from s3_reader import File


def check_s3_file(path):
    file = File(path)

    with open(file.path) as f:
        ...

check_s3_file('s3://<bucket>/path/to/file')

In this example, the S3 file is downloaded when file = File(path) is executed, and it is stored as a temporary file.

file.path refers to the path of the locally stored temporary file.

At the end of the check_s3_file function, the file object is deleted, and consequently, the temporary file is also deleted.

If path refers to a local file instead of an S3 file, File simply copies the path, and you can use the File object in the same manner.
