The ImportError you're spotting is due to Python 3 renaming the classic ConfigParser to now configparser. Revise your import flare:

import configparser

For cross-version compatibility, toss the exception thusly:

try:
    import configparser    # Python 3 anticipates you, ready to party 🎉.
except ImportError:
    import ConfigParser as configparser  # Python 2 grudgingly invites you, "Don't touch anything! 😠".

With this, your code's compatibility stakes even between the Python 2 and 3 clans without needing a longer war treaty.

Bridging to Python 3 - Smoother than you think!

Upgrading to Python 3 involves a couple of hurdles such as ImportError popping up if your old friend was Python 2, all thanks to few renamed or upgraded modules. How to ace this upgrade:

Follow PEP 8 guidelines when revamping your code for Python 3, maintaining readability and consistency. PEP 8, the secret recipe to elegant code.
Do a compatibility check of all packages with Python 3; don't leave behind your old projects and scripts.
Invoke pip3 to install packages specifically for Python 3 environments, avoiding ambiguity akin to ordering a pizza with "some toppings".

No Compatibility? No Fret.

When you encounter compatibility issues, you have these moves up your sleeves:

Opt for alternative packages that are Python 3-compatible, if the one you are using is not. Believe me, there's always another fish!
Look for community-supported forks to find the upgraded, Python 3-friendly version of your needed package.
Instead of renaming modules (and possibly creating a mess), use six or future for effortless cross-compatibility. They are the peacekeepers!
Consider virtual environments for efficient dependency management and avoiding clashes between Python 2 and 3 armies.

Street smart solutions for Python 3

When code compatibility becomes a speed bump:

Replace MySQL-python with its Python 3 knockout twin, mysqlclient.
Ensure python3-dev and libmysqlclient-dev are set up in your system before installing mysqlclient. Checks complete? Buckle up!

Sharing is caring:

Post successful solutions to forums to boost the community, climb some karma ladder!
Engage in community forums for additional support. United we code, divided we ImportError.

The Virtues of Virtual Environments

For an easily manageable dependency structure:

Utilize virtual environments. It separates your Python environment into neat, little rooms avoiding any chaos.
Keep a track of required packages together in a requirements.txt for future references. I mean, who doesn't love a neatly compiled packing list!
