Subject: Beginner - list not returning correct variable value
Date: Thu, 13 Mar 2014 16:12:28 +0000
Hello Tutor,
I am a self-taught Python script beginner and I do it from the Michael Dawson
Book.
In attached script, can somebody tell me why the values of the variables
strenght_points, health_points, wisdom_points and dexterity_points stay at 0
value when 'printing' their value from the list attributes[] when the 'for'
loop at the bottom of the script runs.
I have commented out the script to highlight what causes me problem.
I hope this is clear enough a question.
Thanks for your help,
Marc
