Hi, I'm new to programming in Python, & I need help. I am trying to read from a text file, which contains:

1 4 5 3

1 0 2 4 18

5 2 0 0 9

I am suppose to implement a Simplex algorithm that can hopefully solve these numbers. So far, I am able to make the program print out the numbers as a 2d array. I have each line of the text file saved as an array. For example, array[0] = [1, 4, 5, 3]. I know the trick to the simplex method is to convert the equation into linear equations, thus using arrays would be the wisiest choice. However I'm stuck in making the initial matrix (sometimes called the "tableau"). Can anyone help me? I'd appreciate it

Here's my code:

```
import sys
import string
import array
import os
import array
#initialize empty lists
#objective = [] #1st line of text file, the objective
#constraint1 = []
#constraint2 = []
inputfile = "input file.txt" #input file
#read the data in the file:
def readinputfile(inputfile):
f = open(inputfile, "r") #read from file
data = f.read() #read the entire file
return data #return the data
#Simplex algorithm
def simplex(inputfile):
f = file(inputfile, "r") #read from file
array = [line.split() for line in f] #save data in a 2d array
#show data BEFORE simplex algorithm
print "Data in file, before performing simplex method:"
print "\t", array[0] #print arrays
print "\t", array[1] #array[1] & array[2] are the initial matrices
print "\t", array[2]
#now, solve with simplex method
for array in range(f):
if array == 4:
print array
f.close() #close the file
```
