2Qs

1st question:

If a make an exe with i.e. py2exe, can I get any kind of error/bug
report from the exe file saved into a file error.log and how?

2nd question:

is there a better way to do this:

<code>
def tritup(x,y,z):
#here is a while loop giving 3 results, i.e. r1,r2,r3
return r1,r2,r3

#I want to put sum of r1,r2,r3 as a condition in if statement
#so I created a function to do this, but I can't escape a feeling
#there is a more elegant solution, especially in python ;=)

def summm(a,b,c):
return a+b+c

if x>10 and y>10 and z>10 and summ(tritup(x,y ,z)): print "OK"

Re: 2Qs

SuperHik, for the second question there is builtin sum():
[color=blue][color=green][color=darkred]
>>> values = 10.5, 5, -12
>>> sum(values)[/color][/color][/color]
3.5

Your if becomes:

if x>10 and y>10 and z>10 and sum(tritup(x,y, z)):
print "OK"

if x>10 and y>10 and z>10 and sum((x,y,z)): print "OK"

Write the program to write a log file as it runs?

Others have already suggested you use the built-in sum() function.

I'll suggest you don't need it at all, because it is redundant.

If the sum is zero, either all three values are zero or at least one of
the values is negative. In either case the first test will fail.

There are no circumstances where each of x, y and z are greater than 10
but the sum is zero; nor are there any circumstances where the sum is
zero but x, y and z are still all greater than 10.

Unless, of course, the function tritup returns negative values. My
guess is that the "> 10" tests are protecting the tritup function, and
possibly should be moved there. Without the details of the function, I
can't tell, but it may be incorrect to remove those tests.

Which brings us to the other bit of advice - unit tests protect you
from yourself and from those who optimize too quickly.
