Question

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)])]

我想替换此订单

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

带有以下字符串：categories = [＆＃39;艺术和娱乐＆＃39;，＆＃39;激情点＆＃39;，＆＃39;积极的生活方式＆＃39;，＆＃39;消费习惯＆＃ 39;，＆＃39;精明的旅行＆＃39;]。例如，＆＃39; 2＆＃39;将被类别[2]

取代

我写了以下代码：

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)],

Answer 1

鉴于您有var data = new FormData(); document.querySelector("input[type=file]") .addEventListener("change", function(event) { for (var i = 0, files = event.target.files; i < files.length; i++) { data.append("file-" + [...data.keys()].length, files[i], files[i].name) } })和url_sims1，请尝试：

categories

或者，如果您的起点为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)])]和unique_url，请尝试：

sims1
