Reading Files

Python's open() function opens a file for reading (or writing)

file.readlines() reads the entire contents of file into a list of strings 

    inputfile = open("data.txt", "r")
    data = inputfile.readlines()
    inputfile.close()
    
    for line in data:
        print line





The string package contains functions for manipulating strings

string.split() breaks up a string, based on a separating character, into a list of strings

string.atoi() converts a string to an integer
string.atof() converts a string to a floating point number 

    import string

    for line in data:
        strvalues = string.split(line)
        for str in strvalues:
            x = string.atoi(str)
            print x
