我收到索引错误作为列表超出范围。我必须扫描很多行 [英] I am getting an Index error as list out of range. I have to scan through many lines

问题描述

  import nltk 
从nltk.tokenize导入随机
导入sent_tokenize，word_tokenize 
 
 
 file = open（sms .txt，r）
 for line in file：
 #print line 
a = word_tokenize（line）
 if a [5] =='SBI'和a [ 6] =='借记'：
打印一份[13] 
  

任何人都可以请帮我纠正错误。程序运行几行然后停止并给出索引超出范围错误。我理解错误，但我不知道如何解决它。我想基本上删除不可读的行。

解决方案

只需添加列表长度检查即可解决问题。<如果len（a）> = 14且a [5] =='SBI'和a [6] =='借方'：
打印[13]

import nltk
import random
from nltk.tokenize import sent_tokenize, word_tokenize


file = open("sms.txt", "r")
for line in file:
    #print line
    a=word_tokenize(line)
    if a[5] == 'SBI' and a[6]== 'Debit':
        print a[13]

Could any one please help me in rectifying the error. The programme runs for a few lines then stops and gives an index out of range error. I understand the error but I dont know how to fix it. I want to basically remove the lines which have are not readable.

解决方案

Just add a list length check would solve the problem.

if len(a) >= 14 and a[5] == 'SBI' and a[6]== 'Debit':
    print a[13]
