I've been flying Clippers for months, and I decided to try the Python for CZ, maybe the extra large hard point will help me kill stuff faster.
Turns out, it doesn't feel that way at all, the energy capacitor seems to drain faster, so you only do more damage in that initial burst, the turn speed is so slow it is hard to keep the aim at the small ships, and since the speed is also slow, enemy ships just run away from you and going from one target to another is also slower.
I also got my canopy broken as soon as the shields went down, didn't even have time to finish of an NPC Clipper before I had to jump out, I recall the Clipper giving a bit more margin.
It feels that the only thing this ship has over the Clipper is the ability to dock in outposts. I'll probably run a few tests with actual numbers to compare the moneymaking with the Clipper, but lest just say I'm far from sold, plus the lack of style is the biggest problem
First I'd have to say it seems you are flying a low grade Python with weapons that are too power hungry for it´s current power plant.
It is not clear what weapons you use, but it sounds like they might be 3 size 3 beams?
You just need to fit the weapons that fit the power you can supply them with.
That is nothing the Python can be blamed for.
It is the responsibility of the commander

.
Ships in ED are a very personal thing. I love my Python although it has it´s shortcomings, the vulnerable canopy being one of them.
I hope that in the future we will be able to upgrade canopies. The Python really needs it.
Turn speed is low, although you can use boost to speed it up in certain situations.
When confronted with agile ships this can be a problem.
I have been experimenting a lot with weapon configurations for the Python and I found turrets to be the solution for it´s slow turning speed.
I have outfitted my heavily armoured Python with turrets in every hard point.
You lose damage output, but in practice this does not matter, because you can keep firing continuously at agile targets.
They can not outmaneuver turrets.
I have killed dozens of Clippers with my Python. One on one they can not beat my Python.
They can run away, which I consider to be a win for me.
If lack of style is your biggest problem, then there´s nothing I can say.
Style is personal taste.
The Clipper is a great ship to fly, but personally I am not a fan of her looks, with that grossly oversized canopy.
Conda is much better a combat ship compared to python in my opinion
It depends on the situation. I personally love to take out elite Anacondas in my Python in Warzones.
There is also a slight difference in price to be considered. A basic Anaconda is almost three times the price of a basic Python.
