ok，所以我真的不理解函数ATM和我的任务是创建一个单独的python模块，它具有使程序运行所需的所有函数。这个课程是教授提供的，已经完成了，我不能更改。我并不是要求任何人坐在这里，自己完成所有的功能，虽然这将是惊人的，我只需要完成一两个，也许是一个解释他们是如何工作的。下面是给我的完整的程序。

import lab06_bubbles as bubbles
import random
# @@@ NOTE: In this lab, I *DON'T* want you to change anything in this file. I want you to create
# lab06_bubbles.py so that this works as described in the lab document (and video) @@@

win_height = 800
pygame.display.init()
pygame.font.init()
screen = pygame.display.set_mode((win_width, win_height))
font = pygame.font.SysFont("Courier New", 12)
clock = pygame.time.Clock()
done = False
numBubbles = random.randint(50, 100) # Initial number of bubbles
numWebs = 2 # Initial number of connections between each bubble
paused = False # Are we paused?
minAreaWidth = 50 # The minimum width of the bubble area
maxAreaWidth = win_width # The maximum width of the bubble area
minAreaHeight = 50 # The minimum height of the bubble area
maxAreaHeight = win_height - 50 # The maximum height of the bubble area
# Generate the initial play area and bubble list
currentArea = bubbles.randomArea(minAreaWidth, minAreaHeight, maxAreaWidth, maxAreaHeight)
bubbleList = bubbles.spawnBubbles(numBubbles, currentArea, 5, 20, 100)
# Game Loop
while not done:
# @@@@@@@@@@@@@

if numBubbles > 100:

if numWebs < 0:
numWebs = 0

bubbleList = bubbles.spawnBubbles(numBubbles, currentArea, 5, 20, 100)
elif event.key == pygame.K_p:
paused = not paused
# @@@@@@@@@@@@@
# @ DRAW @
# @@@@@@@@@@@@@
screen.fill((0,0,0))
pygame.draw.rect(screen, (255,255,255), currentArea, 1)
bubbles.drawBubbles(bubbleList, screen, numWebs)
screen.blit(font.render("# Bubbles: " + str(len(bubbleList)) + " area: " + str(currentArea) +
" num_webs: " + str(numWebs), False, (128,128,128)), (0, win_height - 48))
screen.blit(font.render("[Left / Right] : decrease / increase number of bubbles [space]: regenerate bounds [escape]: quit",
False, (128,128,128)), (0, win_height - 32))
screen.blit(font.render("[Up / Down] : decrease / increase number of connections [p]: pause", False,
(128,128,128)), (0, win_height - 16))
pygame.display.flip()
# Pygame shutdown
pygame.font.quit()
pygame.display.quit()
这是给我的函数大纲模块，这是我不知道该怎么做的地方。

我只是需要一些帮助。这就是最终产品的样子。
首先，我不会帮你做作业，但我可以试着给你以下提示:
每次在python脚本中使用import语句导入一个模块(另一个脚本的奇特名称)时，python将在两个地方查找该模块:
- 当前工作目录(通常是你正在处理的脚本所在的文件夹)
- 如果在当前工作目录中找不到它，它将在Python安装的库中查找它。
所以你要做的第一件事，就是确保lab06_bubbles和你要运行的脚本在同一个目录下。
然后，由于您的教授将lab06_bubbles导入为bubbles，因此在他的程序中提到bubbles.function的任何地方，它都将在lab06_bubbles.py文件中查找该函数，您必须在该文件中构建程序所需的所有函数。
然后教授给你构建函数所需的所有信息:
- 参数是什么
- 函数应该返回什么
你，必须在中间施展魔法。
假设其中一个函数名为getDist，描述如下:
def getDist(pointa, pointb):
"""
Takes two points, and return the distance between those points.
:param pointa: a tuple with the x, y coordinates of point a
:param pointb: a tuple with the x, y coordinates of point b
:return: a float representing the distance between the two points
"""
则需要按照如下方式编写函数:
def getDist(pointa, pointb):
xa,ya = pointa
xb,yb = pointb
dist_ab = ((xa-xb)**2+(ya-yb)**2)**0.5
return float(dist_ab)
希望能有所帮助
