使用反斜杠(/)从文本文件中删除文件路径

Question

import re
b = open ('Filter_Lines.txt','w')
with open('Lines.txt') as f:
    for trim in f:
        repl = (re.sub('D:.*\\\\\\\\','',trim).rstrip('\n'))
        b.write(repl + '\n')

b.close()

这是我从文本文件中删除目录路径的示例代码。如果"\\“slashes.But不适用于”/“目录，则此代码运行良好。

我有一个文本文件和下面的这些行。

1.大型D:/Dolby_Harmanious_kit/Dolby_Atmos_for_Sound_Bar_Products_SIDK/Test_Materials/Test_Signals/upmix_multitone/upmix_multitone_c/truehd/upmix_multitone_c_6ch_to_8ch.mlp -of out_dut.wav

2.大型D:/Dolby_Harmanious_kit/Dolby_Atmos_for_Sound_Bar_Products_SIDK/Test_Materials/Test_Signals/upmix_multitone/upmix_multitone_l/truehd/upmix_multitone_l_6ch_to_8ch.mlp -of out_dut.wav

3.大型D:/Dolby_Harmanious_kit/Dolby_Atmos_for_Sound_Bar_Products_SIDK/Test_Materials/Test_Signals/upmix_multitone/upmix_multitone_lfe/truehd/upmix_multitone_lfe_6ch_to_8ch.mlp -of out_dut.wav

在这里，我需要移除路径。

"D:/Dolby_Harmanious_kit/Dolby_Atmos_for_Sound_Bar_Products_SIDK/Test_Materials/Test_Signals/upmix_multitone/upmix_multitone_c/truehd/“喜欢不同的路径线。你能指点我吗。

import re
b = open ('Filter_Lines.txt','w')
with open('Lines.txt') as f:
    for line in f:
        repl = (re.sub('(D:.*\\\\)|(D:.*/)','',line).rstrip('\n'))
        b.write(repl + '\n')

b.close()

据我所知，您需要windwos和linux路径，也许您的驱动器号会改变，因此您可以将其参数化：

b = open ('Filter_Lines.txt','w')
DRIVE = "E:" #windows

with open('filetest') as f:
    for trim in f:
        repl = (re.sub('(' + DRIVE +'.*\\\\)|('+ DRIVE + '.*/)','',trim).rstrip('\n'))
        b.write(repl + '\n')

b.close()

编辑 os.sep版本

import os
import re
b = open ('Filter_Lines.txt','w')
DRIVE = "E:" #windows
SEP = os.path.sep

if (SEP=="\\"): 
    SEP="\\\\"


with open('filetest') as f:
    for line in f:
        repl = (re.sub( DRIVE +'.*'+SEP,'',line))
        b.write(repl)

b.close()
