我试图用15种不同的颜色在地图上标出15种不同风暴的路径。路径的颜色应取决于风暴的名称。例如，如果风暴的名字是奥黛丽，那么在地图上风暴路径的颜色应该是红色。有人能帮我指个方向吗？

下面是我的代码：import numpy as np

from mpl_toolkits.basemap import Basemap

import matplotlib.pyplot as plt

import csv, os, scipy

import pandas

from PIL import *

data = np.loadtxt('louisianastormb.csv',dtype=np.str,delimiter=',',skiprows=1)

'''print data'''

fig = plt.figure(figsize=(12,12))

ax = fig.add_axes([0.1,0.1,0.8,0.8])

m = Basemap(llcrnrlon=-100.,llcrnrlat=0.,urcrnrlon=-20.,urcrnrlat=57.,

projection='lcc',lat_1=20.,lat_2=40.,lon_0=-60.,

resolution ='l',area_thresh=1000.)

m.bluemarble()

m.drawcoastlines(linewidth=0.5)

m.drawcountries(linewidth=0.5)

m.drawstates(linewidth=0.5)

# Creates parallels and meridians

m.drawparallels(np.arange(10.,35.,5.),labels=[1,0,0,1])

m.drawmeridians(np.arange(-120.,-80.,5.),labels=[1,0,0,1])

m.drawmapboundary(fill_color='aqua')

color_dict = {'AUDREY': 'red', 'ETHEL': 'white', 'BETSY': 'yellow','CAMILLE': 'blue', 'CARMEN': 'green',

'BABE': 'purple', 'BOB': '#ff69b4', 'FREDERIC': 'black', 'ELENA': 'cyan', 'JUAN': 'magenta', 'FLORENCE': '#faebd7',

'ANDREW': '#2e8b57', 'GEORGES': '#eeefff', 'ISIDORE': '#da70d6', 'IVAN': '#ff7f50', 'CINDY': '#cd853f',

'DENNIS': '#bc8f8f', 'RITA': '#5f9ea0', 'IDA': '#daa520'}

# Opens data file witn numpy

'''data = np.loadtxt('louisianastormb.csv',dtype=np.str,delimiter=',',skiprows=0)'''

'''print data'''

colnames = ['Year','Name','Type','Latitude','Longitude']

data = pandas.read_csv('louisianastormb.csv', names=colnames)

names = list(data.Name)

lat = list(data.Latitude)

long = list(data.Longitude)

colorName = list(data.Name)

#print lat

#print long

lat.pop(0)

long.pop(0)

latitude= map(float, lat)

longitude = map(float, long)

x, y = m(latitude,longitude)

#Plots points on map

for colorName in color_dict.keys():

plt.plot(x,y,'-',label=colorName,color=color_dict[colorName], linewidth=2 )

lg = plt.legend()

lg.get_frame().set_facecolor('grey')

plt.title('20 Hurricanes with Landfall in Louisiana')

#plt.show()

plt.savefig('20hurpaths1.jpg', dpi=100)

我一直收到的错误信息是：Traceback (most recent call last):

File "/home/mikey1/lstorms.py", line 51, in

plt.plot(x,y,'y-',color=colors[names], linewidth=2 )

TypeError: unhashable type: 'list'
