[Tutor] The better Python approach

[Robert Berman]

Alan,

Thank you for the clarification. Using that as my guide, I revamped my 
solution to this small challenge and attempted to make the script as 
concise as possible. The challenge is at the Challenge-You web page,
http://www.challenge-you.com/challenge?id=61

I am relatively certain I could have made it  more concise with some 
more detailed examination. If there are some obvious glaring 
deficiencies, please, anyone feel free to  comment.

Thanks,

Robert Berman

#!/usr/bin/env python
#findsum.py

import string

def openinput(thepath = '/home/bermanrl/usbdirbig/Challenges/sum.txt'):
    ''' Opens text file '''
    try:
        infile = open(thepath,  'r')
    except:
        print 'Open file failure.'  
    return infile

def runprocess():
    '''Reads file and passes string to parsing function '''
    bigtotal = 0
    myfile = openinput()
    for line in myfile:
        jlist = line.split()
        for x in jlist:
            bigtotal += int(x)
    print bigtotal
    return
 
if __name__ == '__main__':
    runprocess()
