import - best way to register all classes in a folder in python -

-

i working summer intern @ large company, me , intern has been tasked writing background service scratch in python(with given specifications). can't python expert try write code possible , follow practice. describe service in easy way receives messages buss (amqp atm) , matches them against patterns , preform actions depending on pattern, configurable json file.

to down point, service suppose general , therefore developer should able add different inputs , outputs classes. structure have right now.

  • service.py
  • input
    • __init__.py (includes .py files in __all__ variable)
    • base.py
    • amqp.py

service.py

from input import * import input #use input.base.sources

input\base.py

sources = {} def register_input(cls):    sources[cls.input_name] = cls    return cls  class inputbase(object):     action(self, params): ...

input\amqp.py

@register_input class amqpinterface(inputbase):     input_name = "amqp"     action(self, params): ...

this works, doesn't nice , creates problems include orders. neither nor senior developer think of more pythonic way of solving this. have ideas how solve problem in more elegant way?

i have similar problem described in how prevent numbers being changed exponential form in python matplotlib figure : i don't want (in special case) weird scientific formatting of axis. problem different have problem @ z -axis. 2-d plots can use ax.get_yaxis().get_major_formatter().set_useoffset(false) . , there no function ax.get_zaxis() what use format z -axis same way? edit: example: from mpl_toolkits.mplot3d import axes3d import numpy np import sys import matplotlib import matplotlib.pyplot pyplot def func(xi, ti): res = 10e3 + np.cos(ti) * np.sin(xi) return res if __name__ == '__main__': timespacing = 20 timestart = 0 timeend = 1 time = np.linspace(timestart, timeend, timespacing) widthspacing = 50 widthstart = 0 widthend = 3 width = np.linspace(widthstart, widthend, widthspacing) reslist = [] matplotlib.rcparams['legend.fontsize'] = 10 fig = pyplot.figure() ax = fig.gca(projection = '3d...

php - Best Light server (Linux + Web server + Database) for Raspberry Pi -

i install web server database on raspberry pi (little computer). computer has 1gb ram. i want know best combination: linux distribution , web server , dbms run local server multiple users minimal latency, use php on server. , best settings performance , not have bugs (memory usage, disable plugin, disable service, etc)? i thought light debian , lighttpd server , sqlite database. solution? i think lighttpd + sqlite great choice. linux distro, debian @ centos or tiny core linux , although i'm not sure of compatibility pi. obviously, can't go wrong raspbian if want use in production , more stable performance, few more pi's , set them in cluster .
