Question

大家好我是python脚本的新手，我需要在我的脚本中提供一些帮助

我有像这样的巨大日志文件

xxxx = "qqqqqqq  5466 78455" yyyy = "wwww" zzzz = "hhhh" mmmm = "aaaa"
xxxx = "qqqqqqq  8795 32133" yyyy = "wwww" zzzz = "hhhh" mmmm = "aaaa"
xxxx = "qqqqqqq  5995 21384" zzzz = "hhhh" mmmm = "aaaa"
xxxx = "qqqqqqq  6546 12346" yyyy = "wwww" zzzz = "hhhh" mmmm = "aaaa"
xxxx = "qqqqqqq  7895 13246" yyyy = "wwww" zzzz = "hhhh" mmmm = "aaaa"
xxxx = "qqqqqqq 64654 94343" yyyy = "wwww" mmmm = "aaaa"

并且此文件继续.....

我需要输出为：

 xxxx          yyyy       zzzz         mmmm
  qqqqqqq        wwww       hhhh         aaaa 
  qqqqqqq        wwww       hhhh         aaaa
  qqqqqqq                   hhhh         aaaa
  qqqqqqq        wwww       hhhh         aaaa
  qqqqqqq        wwww       hhhh         aaaa
  qqqqqqq        wwww                    aaaa

我的代码是

import csv
import re
fread = open(fileread, "r")
resultFile = open("out4.csv",'w')
wr = csv.writer(resultFile)
try:
     for line in fread:
            regex = re.findall(r'"(.+?)"',line)
            wr.writerow(regex) 
finally:
    fread.close()
    resultFile.close()

对于这段代码，我得到的输出为：

  qqqqqqq        wwww       hhhh         aaaa 
  qqqqqqq        wwww       hhhh         aaaa
  qqqqqqq        hhhh       aaaa
  qqqqqqq        wwww       hhhh         aaaa
  qqqqqqq        wwww       hhhh         aaaa
  qqqqqqq        wwww       aaa

我不知道如何获取标题并根据标题放置数据....

请帮助我或让我了解如何做到这一点

提前致谢!!!!

如果您的给定文本文件中只有yyyy和zzzz值是可选的，则可以使用复杂模式匹配整行：

r'(?:xxxx = "([^"]+)") (?:yyyy = "([^"]+)" )(?:zzzz = "([^"]+)" )?(mmmm = "([^"]+)")'

根据csv文件中的标题放置数据
