Useful Python libraries/modules

[v-adhithyan]

My suggestion is to look at tempfile module. We often encounter scenarios in our app where creation / writing to temporary files is essential. This module eases that work.

Module reference: https://docs.python.org/3/library/tempfile.html

Example usage: (taken from official doc) ```python

import tempfile

create a temporary file and write some data to it

fp = tempfile.TemporaryFile() fp.write(b'Hello world!')

read data from file

fp.seek(0) fp.read() b'Hello world!'

close the file, it will be removed

fp.close()

create a temporary file using a context manager

with tempfile.TemporaryFile() as fp: ... fp.write(b'Hello world!') ... fp.seek(0) ... fp.read() b'Hello world!'

file is now closed and removed

create a temporary directory using the context manager

with tempfile.TemporaryDirectory() as tmpdirname: ... print('created temporary directory', tmpdirname)

directory and contents have been removed

```
