Сначала вы хотите написать строку, соответствует ли она шаблону или нет. В противном случае вы выписываете только согласованные строки.
Во-вторых, между чтением строк и записью результатов вам нужно либо обрезать файл (может f.seek(0)
, затем f.truncate()
), или закрыть оригинал и снова открыть его. Выбрав первое, я получаю что-то вроде:
fpath = os.path.join(thisdir, filename)
with open(fpath, 'r+') as f:
lines = f.readlines()
f.seek(0)
f.truncate()
for line in lines:
if '<a href="' in line:
for test in filelist:
pathmatch = file_match(line, test)
if pathmatch is not None:
repstring = filelist[test] + pathmatch
line = line.replace(test, repstring)
f.write(line)
