So where is the code where you prompt the user and read input.
All we can see is a single function?
For some reason I can´t run it. The follwing is what I have written on
my script:
def comparefunc (a, b):
a = 3
b = 4
The above assignments make your parameters useless since you have
overwritten them
This function effectively compares 3 and 4 only. As such the result will
always return -1.
Having func as part of the name is usually considered a bad idea.
We can see its a function by the way we use it. The only time
having func in the name is useful is when you are passing it
as a parameter to another function or storing it in another
variable. But I suspect that's several learning steps away
from you just now.
if a < b:
return 1
elif a == b:
return 0
elif a < b:
return -1
print "return"
This all looks OK except putting prints inside a function like this is
usually only good as a debugging aid. You probably want to lose that
once you have it working correctly.
And, this is what I get for my output:
>>> ================================ RESTART
================================
That may be because you define the function but don't
seem to call it at any point.
You need to remove the two assignments for a and b
Then implement the get input calls to get the values
from the user then call the function and finally print
the result.
Something like this:
a = int(raw_input('gimme an a '))
b = int(raw_input('gimme a b '))
result = camparefunc(a,b)
print result
