[Tutor] Multiples python files
Hi, first sorry for my poor english, i'm a french guy, i'm trying to make
the best :(
I would like to split my python script into multiples files.
I want :
A file which contains only class creations and methods,
A file with some personals functions
And a main.py which is the main script.
But i'm getting some problems
In class creation file, i've a init method which create a character (it
works).
They are created in main.py like this :
herosAll = [
Character(1,"Antaa","Soldat moins fort",15,5,8),
Character(2,"Klaitos","Soldat moins fort",15,5,8)]
But when i want to display all information about my character with :
class Character():
def DisplayAll():
print ('There is', Character.CharacterCount, 'heros')
for heros in herosAll:
heros.DisplayCharacterInfos()
I'm getting :
Traceback (most recent call last):
File "main.py", line 28, in
Character.DisplayAll()
File "/home/christopher/class_creation.py", line 53, in DisplayAll
for heros in herosAll:
NameError: global name 'herosAll' is not defined
I know the source of the problem. The list herosAll is declared in main.py
so he can't access to it. But i'm stuck here. How can he get it ?
Have I to append the list in the init method ?
Thank you for ready.

Re: [Tutor] Search function in a list-tuples
Hi,
I found the solution :)
Special thanks to Alan G.
Solution :
def FindByName(HerosName):
for heros in herosAll:
if HerosName == heros.name:
return heros
return None
HerosName = 'notfound'
while FindByName(HerosName) == None:
HerosName=input("Enter heros name (type exit for close): ")
if HerosName.lower() == 'exit':
Display_menu()
else:
ch = FindByName(HerosName)
if ch:
ch.DisplayCharacterInfos()
newSearch=input('New search ? (Y/N)')
else :
print ('This heros does\'nt exist')

[Tutor] Search function in a list-tuples
Hi, is there a better way to do this ? (*heros are Character*)
herosAll = [
Character(0,"Chris","Soldat fort",type[0],15,5,8,50,1),
Character(1,"Antaa","Soldat moins fort",type[0],15,5,8,50,1)]
def HeroExist(HerosName):
herosId = -1
for heros in herosAll:
if HerosName in heros.name:
herosId = heros.id
if herosId != -1:
return herosId
else:
return -1
I find this solution myself and I think a better one exist..
HerosName=input("Enter heros name : ")
if Character.HeroExist(HerosName) != -1:
herosAll[Character.HeroExist(HerosName)].DisplayCharacterInfos()
else :
print ('This heros does\'nt exist')
Display_menu()

[Tutor] Dictionnaries in object
Hi,
I want to create some powers in my fight program.
I want to know if dictionnaries is the best solution to do it.
For now its look like this :
//French name and description, don't care about it ;)
power1= {}
power1['Name'] = 'Flammes infernales'
power1['Description'] = 'Embrase lenemi et le feu bruler'
power2= {}
power2['Name'] = 'Froid devorant'
power2['Description'] = 'Gele lenemi sur place'
powerAll= [power1,power2]
but if i want to create like 20 powers, it will be long no ? is there any
solution shorter (and better ?)
Thank you for reading,
