RE: Help with Classes - Lonewolf - Feb-16-2019
so i have something like that for coordinates:
a=[]
for j in range(11):
x=random.randint(1,12)
for i in range(29):
y=random.randint(1,29)
a.append(x,y)as for shape it should go something like that?b=[triangle,sphere] random.suffle(b,random.random) print(b)
RE: Help with Classes - buran - Feb-16-2019
You don't need the for loops when you generate x and y. With your code you will generate 11 x values and 29 y values, but at the end you will add just the last pair - 11th x and 29th y, all other are lost. see for yourself
a=[]
for j in range(11):
x=random.randint(1,12)
print('x={}'.format(x))
for i in range(29):
y=random.randint(1,29)
print('y={}'.format(y))
a.append((x,y))
print(a)note that you need extra pair of brackets for the append.when you get the x and y, you don't want to add them to list. you want to create instance of Triangle or Sphere class and use x and y when create that instance
the second snippet - it even doesn't run. Please, pay more attention.

ok thanks!
it's obvious now that i will never solve this exercise!!
i do not understand anything here.
Even if i study again and again and again classes and inheritance i won't make any progress :(
RE: Help with Classes - buran - Feb-16-2019
sorry, but I will not give you ready solution. Period. You either make an effort if you want any more help or just give up and enjoy the weekend. At least I am going to do that now.

loops and lists??
what to look exactly?in my textbooks are only simple examples.Not complicated like the ones this exercise needs.
Sorry if i made you lose your time with me.
if i give up i fail
but i don't get what i must do
RE: Help with Classes - Lonewolf - Feb-17-2019
Still nothing...
RE: Help with Classes - Lonewolf - Feb-17-2019
i tried something:
i created a list with all possible coordinates and then another list with the random 12:
import random
coordinates = []
for x in range(12):
for y in range(30):
coordinates.append((x, y))
for i in range(12):
lilo = random.choice(coordinates)
print(lilo)but i used random.choice and not random.randit (as exercise says 
)now how i instatiate that with the shapes?
-i haven't succeeded yet in creating random shapeds though-
RE: Help with Classes - Lonewolf - Feb-18-2019
Well,thanks for helping me...
i failed!!
RE: Help with Classes - Lonewolf - Feb-18-2019
Since there is no benefit for me now since I didn't submit the assignment can anyone show me the solution to this exercise?
RE: Help with Classes - sonedap - Feb-18-2019
I will try and solve it but I hope so other more experienced will help you.
