I am sorry that i forgot to see the working example. Base on your
example, i can show the value without missing but got the other
problem. I would like to culmulate the value by users. I was rewrite
your example but cannot not work.
##
import sys
import pprint
try:
f = open('data.txt', 'r')
except IOError, e:
print >> sys.stderr, "Cannot open file data.txt for reading : %s"
%e
sys.exit(1)
users = {}
cumdata2 = 0
cumdata3 = 0
for line in f:
try:
user, data1, data2 = line.strip().split('\t')
except ValueError:
print >> sys.stderr, "wrong file format"
f.close()
sys.exit(1)
try:
users[user].append("%s : %s" % (data1, data2))
cumdata2 = int(data2) + cumdata2
except KeyError:
users[user] = ["%s : %s" % (data1, data2)]
cumdata3 = int(data2) + cumdata3
f.close()
print "collected data:";
pprint.pprint(users)
print cumdata2
print cumdata3
##
The above example can run but the total num are wrong. Would you mind
to figure out where is my problem?
Thanks for your prompt help!!!
