bash ldapsearch script to python script

Question

I have a bash script for a simple ldapsearch for user email by it's UID.

I want to make the same thing but in python

Here is what I have:

#!/bin/bash
xargs -I {} \
ldapsearch -x -b '' -LLL -h ldaphost.com -p 255 uid={} mail \
    < file.in \
    >> file.out

Every solution I've found and tried has much more complex query requests when I'm only look to find specific user's email by their UID.
