python中的索引不足

我试图对excel文件进行索引，我使用了whoosh软件包，但是，我 发现列表索引超出范围的错误。 请问，有人能帮我吗？ 我的代码是：

from whoosh import fields, index
import os.path
import csv
import codecs

# This list associates a name with each position in a row
columns = ["juza","chapter","verse","analysis"]

schema = fields.Schema(juza=fields.NUMERIC,
                       chapter=fields.NUMERIC,
                       verse=fields.NUMERIC,
                       analysis=fields.KEYWORD)


# Create the Whoosh index
indexname = "index"
if not os.path.exists(indexname):
  os.mkdir(indexname)
ix = index.create_in(indexname, schema)

# Open a writer for the index
with ix.writer() as writer:
  # Open the CSV file
  with codecs.open("yom.csv", "rb","utf8") as csvfile:
    # Create a csv reader object for the file
    csvreader = csv.reader(csvfile)

    # Read each row in the file
    for row in csvreader:

      # Create a dictionary to hold the document values for this row
      doc = {}

      # Read the values for the row enumerated like
      # (0, "juza"), (1, "chapter"), etc.
      for colnum, value in enumerate(row):

        # Get the field name from the "columns" list
        fieldname = columns[colnum]

        # Strip any whitespace and convert to unicode
        # NOTE: you need to pass the right encoding here!
        value = unicode(value.strip(), "utf-8")

        # Put the value in the dictionary
        doc[fieldname] = value

      # Pass the dictionary to the add_document method
      writer.add_document(**doc)
    writer.commit()
`

我得到这个错误，我不知道为什么？ 错误：

---

csv.reader

使用逗号作为默认分隔符：

，

您必须明确定义分隔符：

csvreader = csv.reader(csvfile, delimiter=...)

但是，您的CSV文件不是同质的。阅读时最好不要使用

csv

：

columns = ["juza","chapter","verse","analysis"]
with codecs.open("yom.csv", "rb","utf8") as f:
    for line in f:
        a, b, c, rest = line.split('   ', 3)
        doc = {k:v.strip() for k,v in zip(columns, rest.split(':'))}
        # a,b,c are the first three integers
        # doc is a dictionary

你的意思是我应该删除“csvreader”并用你建议的代码替换它吗？但是如果我这样做，现在的问题是如何在下面的行中显示字段名：“fieldname=columns[colnum]”@user2091683-您不再需要

colnum

zip（columns，rest.split（“：”）

将它们“打包”在一起，并且

doc

-字典包含整个条目。这是我的新代码，请打开此链接：（）此错误发生：回溯（最近一次调用）：文件“C:\Python27\yarab.py”，第26行，在juza，chapter，verse，analysis=line.split（“”，3）ValueError:需要多个值才能执行此操作unpack@user2091683-检查您的csv文件是否真的在四个主列之间有三个空格作为分隔符，如果需要，请更改该行。但是如何知道两个列之间没有空格？

csvreader = csv.reader(csvfile, delimiter=...)

columns = ["juza","chapter","verse","analysis"]
with codecs.open("yom.csv", "rb","utf8") as f:
    for line in f:
        a, b, c, rest = line.split('   ', 3)
        doc = {k:v.strip() for k,v in zip(columns, rest.split(':'))}
        # a,b,c are the first three integers
        # doc is a dictionary
