我有一些我想運行的代碼。 進出口新的蟒蛇,以及計算器AttributeError:'模塊'對象沒有屬性'新'
這裏是Python程序:
# Circle Inversion Fractals (Apollonian Gasket) (Escape-time Algorithm)
# FB36 - 20131031
import math
import random
from collections import deque
from PIL import Image
imgx = 512; imgy = 512
image = Image.new("RGB", (imgx, imgy))
pixels = image.load()
n = random.randint(3, 6) # of main circles
a = math.pi * 2.0/n
r = math.sin(a)/math.sin((math.pi - a)/2.0)/2.0 # r of main circles
h = math.sqrt(1.0 - r * r)
xa = -h; xb = h; ya = -h; yb = h # viewing area
cx = [0.0]; cy = [0.0]; cr = [1.0 - r] # center circle
for i in range(n): # add main circles
cx.append(math.cos(a * i))
cy.append(math.sin(a * i))
cr.append(r)
maxIt = 64 # of iterations
for ky in range(imgy):
print str(100 * ky/(imgy - 1)).zfill(3) + "%"
for kx in range(imgx):
x = float(kx)/(imgx - 1) * (xb - xa) + xa
y = float(ky)/(imgy - 1) * (yb - ya) + ya
queue = deque([])
queue.append((x, y, 0))
while len(queue) > 0: # iterate points until none left
(x, y, i) = queue.popleft()
for k in range(n + 1):
dx = x - cx[k]; dy = y - cy[k]
d = math.hypot(dx, dy)
if d <= cr[k]:
dx = dx/d; dy = dy/d
dnew = cr[k] ** 2.0/d
xnew = dnew * dx + cx[k]
ynew = dnew * dy + cy[k]
if xnew >= xa and xnew <= xb and ynew >= ya and ynew <= yb:
if i + 1 == maxIt: break
queue.append((xnew, ynew, i + 1))
pixels[kx, ky] = (i % 16 * 16 , i % 8 * 32, i % 4 * 64)
image.save("CircleInversionFractal_" + str(n) + ".png", "PNG")
當我運行它,我得到一個錯誤消息,但我不知道如何解決它。
Traceback (most recent call last):

AttributeError: 'module' object has no attribute 'new'
這個追溯是什麼意思?
如果您分享您嘗試使用的代碼,這將有助於提供更詳細的答案。也許你正試圖在Python中使用Ruby語法來實例化一個對象? –
請分享您的代碼,以便我們可以幫助您*更正錯誤。你正在嘗試使用'hmac','sha','md5'還是'hashlib'模塊? –
