python-3.3

问题 I'm working on writing two different shuffle functions. The first shuffle function must take a list and return a new list with the elements shuffled into a random order. This is what I have so far for the first shuffle function- def shuf(List): import random newList=[] for i in List: i=random.randrange(len(List)) newList+=i return newList The second shuffle function takes a list as a parameter and shuffles the list in place. I know how to do it with the built-in function but I'm not allowed

问题 I'm using basemap to plot some points on a map, and I want to add any kind of animation to it. It could literally serve no purpose at all, as long as it is an animation it would be nice. This is what I currently have to make the map, from mpl_toolkits.basemap import Basemap import matplotlib.pyplot as plt import numpy as np import matplotlib.animation as animation map = Basemap(projection='robin', resolution = 'l', area_thresh = 1000.0, lat_0=0, lon_0=-130) map.drawcoastlines() map

问题 I'm trying to use Pygame with Python 3.3 on my windows 8 laptop. Pygame installed fine and when I import pygame it imports fine as well. Although when I try to execute this small code: import pygame pygame.init() size=[700,500] screen=pygame.display.set_mode(size) I get this error: Traceback (most recent call last): File "C:\Users\name\documents\python\pygame_example.py", line 3, in <module> pygame.init() AttributeError: 'module' object has no attribute 'init' I used pygame-1.9.2a0-hg

问题 I try get ration of variable and get unexpected result. Can somebody explain this? >>> value = 3.2 >>> ratios = value.as_integer_ratio() >>> ratios (3602879701896397, 1125899906842624) >>> ratios[0] / ratios[1] 3.2 I using python 3.3 But I think that (16, 5) is much better solution And why it correct for 2.5 >>> value = 2.5 >>> value.as_integer_ratio() (5, 2) 回答1: Use the fractions module to simplify fractions: >>> from fractions import Fraction >>> Fraction(3.2) Fraction(3602879701896397,
