[Tutor] files in a directory

[Jay Loden]

There's a few ways to accomplish this...the way that comes to mind is: 

##########################################################
import glob

files = glob.glob("/path/to/director/*.dml")  # assuming you want only .dml 

def spot(file):
  '''search for intensity spots and report them to an output file'''
  f1 = open('my_intensity_file.dml','r')
  int = f1.read().split('\n')

  my_vals  = intParser(int) 

  intParser return a list
  f2  = open('myvalues.txt','w') # you will want to change this to output mult 
  for line in my_vals:   # files, or to at least append instead of overwriting
      f2.write(line)
    f2.write('\n')
  f2.close()

def main():
  for each in files:
    spot(each)

main()

##########################################################

Basically, turn the parsing into a function, then create a list of files, and 
perform the parsing on each file.  glob() lets you grab a whole list of files 
matching the wildcard just like if you typed "ls *.dml" or whatever into a 
command prompt.  There wasn't too much info about specifically how you needed 
this to work, so this is a rough sketch of what you want. Hopefully it helps.
