Here is my code:

#-------------------------------------------------------------------------------
# Name:        Mocha Rotoscoping Via Blender
# Purpose:     Make rotoscoping more efficient

#!/usr/bin/env python
import sys
import os
import parser
sys.path.append('Z:\_protomotion\Prog\HelperScripts')
import GetDir
sys.path.append('Z:/Blender_Roto')
filename = 'diving_board.shape4ae'
infile = 'Z:/Blender_Roto/'
#import bpy
#from mathutils import Vector

#below are taken from mocha export
x_width =2048
y_height = 778
z_depth = 0
frame = 20

import re

data_directory = 'Z:/Blender_Roto/' # windows
data_file = 'diving_board.shape4ae'
fullpath = data_directory + data_file


print("====init=====")

file = open(fullpath)
for line in file:
    current_line = line

    # massive room for optimized code here.

    # this assumes the last element of the line containing the words
    # "Units Per Second" is the number we are looking for.
    # this is a non float number, generally.
    if current_line.find("Units Per Second") != -1:
        fps = line_split = float(current_line.split()[-1])
        print("Frames Per Second:", fps)

    # source dimensions
    if current_line.find("Source Width") != -1:
        source_width = line_split = int(current_line.split()[-1])
        print("Source Width:", source_width)

    if current_line.find("Source Height") != -1:
        source_height = line_split = int(current_line.split()[-1])
        print("Source Height:", source_height)

    # aspect ratios
    if current_line.find("Source Pixel Aspect Ratio") != -1:
        source_px_aspect = line_split = int(current_line.split()[-1])
        print("Source Pixel Aspect Ratio:", source_px_aspect)

    if current_line.find("Comp Pixel Aspect Ratio") != -1:
        comp_aspect = line_split = int(current_line.split()[-1])
        print("Comp Pixel Aspect Ratio:", comp_aspect)


    # assumption, ae file can contain multiple mocha shapes.
    # without knowing the exact format i will limit the script
    # to deal with one mocha shape being animated N frames.

    # this gathers the shape details, and frame number but does not
    # include error checking yet.
    if current_line.find("XSpline") != -1:

        # record the frame number.

        frame = re.search("\s*(\d*)\s*XSpline", current_line)
        if frame.group(1) != None:
            frame = frame.group(1)
            print("frame:", frame)


        # pick part the part of the line that deals with geometry
        match = re.search("XSpline\((.+)\)\n", current_line)

        line_to_strip = match.group(1)
        points = re.findall('(\(.*?\))', line_to_strip)
        print(len(points))
        for point in points:
            print(point)

file.close()

here is my output:

====init=====
Frames Per Second: 24.0
Source Width: 2048
Source Height: 778
Source Pixel Aspect Ratio: 1
Comp Pixel Aspect Ratio: 1
frame: 20
5
(0.793803,0.136326,0,0.5,0)
(0.772345,0.642332,0,0.5,0)
(0.6436,0.597615,0,0.5,0)
(0.70082,0.143387,0,0.5,0.25)
(0.70082,0.112791,0,0.5,0)

I want to figure out how to call out individual points given. For example, how would I have the code just spit out 0.793803, or just spit out 0.136326, etc etc

Thanks for your help in advance!

Well, you have several tuples given as output - why not use a for loop to print each point inside that tuple? Or am I not understanding you correctly?
