Question

looking for application developer that has advanced Mac OS X IDLE python shell scripting skills that can develop a python application that can open six files, read fields from six files and do string comparisons and computations, writing numerical and string data to an output file. Mac OS X Unix experience is a plus

Answer 1

To making it simple to understand I will only do three files. I assume file text are in 1 line. I also assume you want to compare and check which are common.

import itertools

# reading files.

file1 = open('file1','r').read()

file2 = open('file2','r').read()

file3 = open('file3','r').read()

# def to create a file txt to list.

def splitter(file):

f = []

for x in file.split(' '):

f.append(x)

return f

# getting the list from splitter func.

f1 = splitter(file1)

f2 = splitter(file2)

f3 = splitter(file3)

# get the only common.

for x,y,z in itertools.product(f1,f2,f3):

if x == y == z:

result = x

# creating a empty list.

list = {}

# def to get number of times the word contain.

def counterNum(lst):

for x in lst:

if x in result:

list[x] = list.get(x,0)+1

# just running the counter

counterNum(f1)

counterNum(f2)

counterNum(f3)

keys = list(list.keys())

output = open('output.txt','a+')

for x in keys:

output.write(x + ':' + str(list[x]) + '\n')

# done.
