Hi Al,
To add to Richard’s comment, the specific error is your print statement: I
think you meant to print the value stored in eventCount, not eventcount which
wasn’t declared at all.
Cheers,
Joseph

You have evencount not evenCount in your print statement. Python is case
sensitive.

Subject: [pythonvis] Trace back error
Hi Listers,
I created a separate program for the first sample loop program from Joseph and
ran it. The answer displayed was 53. Not accepting this answer, I attempted to
modify my program to print out each loops data fields: the number being
examined and the counter value of even numbers. When that program was run, it
produced a trace back error which said that "evencount is not defined.
Would someone tell me what I did wrong? Program code is below.
TIA, Al B
# sample loop program from Joseph
import random
random.seed()
l = []
for i in range(0, 100): l.append(random.randint(0, 100))
evenCount = 0
for numbers in l:
if numbers%2 == 0: evenCount+=1
print numbers%2 , evencount
print evenCount
# The following statement halts the program
# so you can look at the screen
raw_input("press Enter to end program")
