Of course, but the top PP for the Python is 51mil by itself.
I agree though, even with the top powerplant, large beams are overly power hungry and WEP capacitor-destroying - you're better off using the C3G Pulse lasers for the C3 hardpoints.
I had this until last night, when I finally ground enough RES Anaconda's to buy the 7A Powerplant. Good (Python) bang for buck, resilient and (reasonably) agile.

Managing the power on this, you can run all day in a RES, with 8 shield charges as safety net; and with strong shields to begin with. Plenty of melting power and reasonable agility for around 92-97% power usage (and thats just on the 7C power plant). You can run A-class thrusters, a bit better scanners etc too if you have the budget, as well as 5A shield cells for more shield boosting power. Keep resisting the urge to fit large beams...for RES the pulses are where its at.
And, if a CMDR shows up and has a go at you, the extra armour
will help. The added 28tons of weight is +210 on top of the base 260 armour, so... ~80%+ more armour, and for a lot less than the 26-tons of reinforced bulkheads (20+mil). Purists will say it slows you down, but really? 28 tons of vs a total 770+ tons of ship mass? No, just no.
Anything you don't need in Supercruise (AFM, FSD, Cargo Hatch, Interdictor, one of the cell banks), set to priority 5 so it all switches off when you drop into a RES.
Easy, and fun.
Best bang for buck still goes to the toy Vulture, but the Python is a stately lady, with teeth.
