Take a look at the strategy pattern. But with python being a dinamic
language, you probably won't need to implement it like that.

http://en.wikipedia.org/wiki/Strategy_pattern

Example:

# import all you need
CAMERAS = ['A','B','C']
def capture_A:
 pass

def capture_B:
 pass

def capture_C:
 pass
def capture(camera):
 if camera in CAMERAS:
  if camera = 'A':
   function = capture_A

  if camera = 'B':
   function = capture_B

  if camera = 'C':
   function = capture_C

  # call function
  function()
 else
  return
