Question

path = r'C:\Myfolder\data\today'
for root, directories, filenames in os.walk(path):

    for filename in filenames:
        fname = os.path.join(root,filename)
        if os.path.isfile(fname) and fname[-4:] == '.log':
            if fname not in rows1:
               print fname
               fname=fname.replace(path,"")
               with open(fname, 'r') as myfile:

我的文件名看起来像C：\ Myfolder \ data \ today \ 00.log，我只需要＆＃34;今天\ 00.log＆＃34; 错误是IOError：[Errno 2]没有这样的文件或目录：＆＃39; \ today \ 00.log＆＃39; 如何从文件名中删除\？

此外，没有真正的错误，你不应该使用replace去掉已知的前缀，而是使用字符串切片并使用完整的文件名来打开文件：

path = r'C:\Myfolder\data\today'
for root, directories, filenames in os.walk(path):
    for filename in filenames:
        fullname = os.path.join(root,filename)
        if os.path.isfile(fullname) and fullname[-4:] == '.log':
            if fullname not in rows1:
               print fullname
               fname = fullname[len(path)+1:]
               with open(fullname, 'r') as myfile:
                   do_something

打开时文件名中出现双反斜杠（\\）
