Answer 1

您要做的是删除 . 之间的数据\r and another \r。此处使用的正确方法是正则表达式。

代码：

import re
check="""'Aadhirai' 'A special star' '6' 'Boy' '' "\rgoogletag.cmd.push(function() { googletag.display('div-gpt-ad-1445572280350-0'); });\r" 'Aadhiren' 'Dark' '6' 'Boy' '' 'Aadhish' 'King Commanded Counselled' '5' 'Boy' '' 'Aadhyatm' 'Dhyan' '1' 'Boy' '' 'Aadi' 'First Most important Beginning Ornament Adornment' '6' 'Boy' '' 'Aadia' 'Being a gift' '7' 'Boy' '' 'Aadidev' 'The first God' '1' 'Boy' '' 'Aadijay' 'The first victory' '6' 'Boy' '' 'Aadim' 'Entire universe' '1' 'Boy' '' 'Aadinath' 'The first Lord Lord Vishnu' '4' 'Boy' '' 'Aadipta' 'Bright' '7' 'Boy' '' 'Aadish' 'Full of wisdom Intelligent' '6' 'Boy' '' 'Aadishankar' 'Sri shankaracharya Founder of Adwaitha philosophy' '6' 'Boy' '' 'Aadit' 'Peak Lord of Sun' '8' 'Boy' '' 'Aaditey' 'Son of Aditi' '11' 'Boy' '' '\r        (adsbygoogle = window.adsbygoogle || ).push({});\r    '"""
print re.sub(r"\r.*?\r"," ",check)

输出：

'Aadhirai' 'A special star' '6' 'Boy' '' " " 'Aadhiren' 'Dark' '6' 'Boy' '' 'Aadhish' 'King Commanded Counselled' '5' 'Boy' '' 'Aadhyatm' 'Dhyan' '1' 'Boy' '' 'Aadi' 'First Most important Beginning Ornament Adornment' '6' 'Boy' '' 'Aadia' 'Being a gift' '7' 'Boy' '' 'Aadidev' 'The first God' '1' 'Boy' '' 'Aadijay' 'The first victory' '6' 'Boy' '' 'Aadim' 'Entire universe' '1' 'Boy' '' 'Aadinath' 'The first Lord Lord Vishnu' '4' 'Boy' '' 'Aadipta' 'Bright' '7' 'Boy' '' 'Aadish' 'Full of wisdom Intelligent' '6' 'Boy' '' 'Aadishankar' 'Sri shankaracharya Founder of Adwaitha philosophy' '6' 'Boy' '' 'Aadit' 'Peak Lord of Sun' '8' 'Boy' '' 'Aaditey' 'Son of Aditi' '11' 'Boy' '' '     '

笔记：

• re模块用于进行regex匹配
• \r.*?\r是我要匹配的正则表达式start from \r match everything until next \r

如何使用filter：

"define filtering function"
good = lambda x : not( x.startswith("\r") and x.endswith() )
"use with statement with open!"
with open('/home/rohit/Desktop/output.txt', 'r') as filein:
    with open('/home/rohit/Desktop/output1.txt','w') as fileout1:
       for line in filein:
           cols = line.rstrip("\n").split(',')
           "remove unwanted columns"
           cols = list( filter( good , cols ) )
           for c in cols:
               fileout1.write(c)
