Text file manipulation

[ritesh247]

I am using a text file in the form of 200 columns and 4 rows i.e

4 5 6 7
3 4 5 6
an so on..

i tried using:

openfile =open("variables.txt")
for item in openfile:
    print item

it prints the columns and the rows, but i don't know how to assign the values to my code.

IS THERE ANY method of assigning each variable like lets say row 4 5 6 7 as A = 4, B=5, C =6 and D=7, use these variables in some manipulation and get an answer, and then on the second go it reads the next row and gets a result and like wise.

Yes. Save the data in a list of lists, something like this:

lineList = [line.strip().split() for line in fileObj]

You can then access individual elements of the list using indexes:

lineList[row][column]
