我有以下列表:

url_sims1=[('http://bp.velocityfrequentflyer.com/',
[(2, 0.90452874),
(1, 0.83522302),
(4, 0.77591574),
(0, 0.72705799),
(3, 0.52282226)]),
('http://cartrawler.virginaustralia.com/',
[(3, 0.79298556),
(1, 0.78112978),
(2, 0.76006395),
(0, 0.58570701),
(4, 0.40093967)]),
('https://cartrawler.virginaustralia.com/book',
[(2, 0.9549554),
(1, 0.71705657),
(0, 0.58731651),
(3, 0.43987277),
(4, 0.38266104)]),
('https://fly.virginaustralia.com/SSW2010/VAVA/webqtrip.html',
[(2, 0.96805269),
(4, 0.68034023),
(1, 0.66391909),
(0, 0.64251828),
(3, 0.50730866)]),
('http://www.magicmillions.com.au/',
[(2, 0.84748113),
(4, 0.8338449),
(1, 0.61795002),
(0, 0.60271078),
(3, 0.20899911)])]

我想更换此订单

(2,...) 
(1,...)
(4,...)
(0,...)
(3,...)

包含以下字符串:categories=['艺术和娱乐', '激情点', '积极的生活方式', '消费者习惯', '旅行悟性']。例如,“2”将被类别替换[2]

我编写了以下代码:

for i in xrange(0, len(unique_url)): 
for j in xrange(0, len(sims1)):
for k in xrange(0,len(categories)):
url_sims1[i][j][k][1]+=categories[k]

但我收到此错误:IndexError:字符串索引超出范围

unique_url=['http://bp.velocityfrequentflyer.com/',
'http://cartrawler.virginaustralia.com/',
'https://cartrawler.virginaustralia.com/book',
'https://fly.virginaustralia.com/SSW2010/VAVA/webqtrip.html',
'http://www.magicmillions.com.au/']

sims1=[[(2, 0.90452874),(1, 0.83522302),(4, 0.77591574),(0, 0.72705799),(3, 0.52282226)],
[(3, 0.79298556),(1, 0.78112978),(2, 0.76006395),(0, 0.58570701),(4, 0.40093967)],
[(2, 0.9549554),(1, 0.71705657),(0, 0.58731651),(3, 0.43987277),(4, 0.38266104)],
[(2, 0.96805269),(4, 0.68034023),(1, 0.66391909),(0, 0.64251828),(3, 0.50730866)],
[(2, 0.84748113),(4, 0.8338449),(1, 0.61795002),(0, 0.60271078),(3, 0.20899911)]]

最佳答案

鉴于您有 url_sims1类别,然后尝试:

In [4]: [(url, [(categories[i], x) for i,x in lst]) for url,lst in url_sims1]
Out[4]:
[('http://bp.velocityfrequentflyer.com/',
[('active lifestyle', 0.9045),
('points of passion', 0.8352),
('travel savvy', 0.7759),
('arts and entertainment', 0.7271),
('consumer habits', 0.5228)]),
('http://cartrawler.virginaustralia.com/',
[('consumer habits', 0.793),
('points of passion', 0.7811),
('active lifestyle', 0.7601),
('arts and entertainment', 0.5857),
('travel savvy', 0.4009)]),
('https://cartrawler.virginaustralia.com/book',
[('active lifestyle', 0.955),
('points of passion', 0.7171),
('arts and entertainment', 0.5873),
('consumer habits', 0.4399),
('travel savvy', 0.3827)]),
('https://fly.virginaustralia.com/SSW2010/VAVA/webqtrip.html',
[('active lifestyle', 0.9681),
('travel savvy', 0.6803),
('points of passion', 0.6639),
('arts and entertainment', 0.6425),
('consumer habits', 0.5073)]),
('http://www.magicmillions.com.au/',
[('active lifestyle', 0.8475),
('travel savvy', 0.8338),
('points of passion', 0.618),
('arts and entertainment', 0.6027),
('consumer habits', 0.209)])]

或者,如果您的起点是 unique_urlsims1,则尝试:

 [(url, [(categories[i], x) for i,x in lst]) for url,lst in zip(unique_url, sims1)]
