Running qwalk.py #1

Open sidneyholden1 opened 7 years ago

Hi there,

I'm very new to GitHub so I'm not sure if this is where I should be commenting. But here goes:

I've finally managed to import pygame, but now when I try to run:

python3 qwalk.py

in the command line (python qwalk.py still won't import pygame), I get this error:

Traceback (most recent call last): File "qwalk.py", line 122, in qwalk_me(A) File "qwalk.py", line 87, in qwalk_me pygame.draw.line(DISPLAYSURF, BLUE, Vertex[edge[0]], Vertex[edge[1]], thickness) TypeError: 'map' object is not subscriptable

Any help would be much appreciated.

Just had to add list() to every map(...) i.e. list(map(...)).

The issue was that the syntax is different in Python 3. (what I'm now using).
