Question

我正在尝试使用查找表来替换文本文件中的值

查找表的格式类似于

Search             Replace
Unit Of Measure    Unit of Measure
Bill Of Material   Bill of Material
Reference Item     Reference Material Number

我正在使用re.sub(Search, Replace, File)

我需要为每次迭代执行类似(r'\b Unit Of Measure\b', Replace, File)的操作。

我无法将这些标记放入变量中。

你能帮忙吗？

以下是代码

import re
f1 = open('C:\Scripts\FNR\SearchReplacekey.txt','r')
f = open("C:\Scripts\FNR\log.txt",'a')
f.seek(0)
f.truncate()
f.close()
for line in f1:
    fields = line.split('|')
    a = fields[0]
    Srch = fields[1]
    Repl = fields[2]
    f = open("C:\Scripts\FNR\Output.txt",'r')
    filedata = f.read()
    check = re.search(Srch,filedata)
    f.close()

    if check == -1:

        f = open("C:\Scripts\FNR\log.txt",'a')
        newdata = a + ' ' + Srch + ' ' + Repl
        f.write(newdata + "\n")
        f.close()
    else:

        # the problem is here I need to force Srch to match exact word
        newdata = re.sub(Srch,Repl,filedata)

        f = open("C:\Scripts\FNR\Output.txt",'w')
        f.write(newdata)
        f.close()

谢谢， Kowsik

Answer 1

我不确定你在问什么，但可能就是这样：

searchs = ["Unit Of Measure", "Bill Of Material"]
for s in searchs:
  re.sub(s, Replace, File)

也许我在这里遗漏了一些东西，但是如果你把这些模式用引号括起来，这似乎运作得很好。
