好吧所以我真的不懂函数atm，我的任务是创建一个单独的python模块，它具有运行程序所需的所有功能。该计划由教授提供，已经完成，不能由我改变。我不是要求任何人坐在这里自己完成所有功能，虽然那会很棒，我只需要完成一两次，也许可以解释它们是如何工作的。以下是给我的完成程序。
import pygame
import lab06_bubbles as bubbles

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:

paused = not paused
# @@@@@@@@@@@@@

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()
这是给我的功能大纲模块，这是我不知道该怎么做的地方。

我需要一些帮助。这就是final product的样子。
答案 0 :(得分：0)
首先，我不会为你做任务，但我可以通过给你以下线索尝试帮助：
每次在python脚本中使用import语句导入模块（另一个脚本的花哨名称）时，Python都会在两个地方寻找该模块：
所以你想要的第一件事就是确保lab06_bubbles与你将要运行的脚本位于同一目录中。
然后，既然你的教授将lab06_bubbles导入为bubbles，那么在他提到bubbles.function的程序中的任何地方都将会在lab06_bubbles.py文件中查找该函数必须构建程序所需的所有功能。
然后教授会为您提供构建该功能所需的所有信息：
你，必须在中间做魔术。
说其中一个函数名为getDist，其描述如下：
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
"""
您需要按以下方式对函数进行编码：
def getDist(pointa, pointb):
xa,ya = pointa
xb,yb = pointb
dist_ab = ((xa-xb)**2+(ya-yb)**2)**0.5
return float(dist_ab)
