Comparing versions with Fabric

Question

I need to compare the version of the installed maven package with a minimum version, using fabric. That's a simple x.y.z version number. Is there any fabric or python library with a function to do that, or a simple way of doing it?

Answer 1

Here's a trick to do it, used by Python itself:

def versioncmp(current, required):
    current = [int(i) for i in current.split('.')]
    required = [int(i) for i in required.split('.')]
    return current >= required
