Pythonos.path.isfile文件抱怨映射网络驱动器中的文件不存在

Question

在本地网络中共享的文件夹映射到Windows10中的网络驱动器（letterV:）。以下python行检查文件是否存在于映射的网络驱动器中：

import os
print(os.path.isfile("V:\\FORENSOR DTB Dataset processed\\pow_day_125236_07.5.avi"))

返回false。文件夹中的任何文件都会发生同样的情况。^来自shutils的{}也抛出文件不存在的错误。但是文件在文件夹中。这里有什么问题？你知道吗

在建议/链接的答案之后，我尝试了以下所有方法（V:是驱动器号，DARAS-NAS是网络位置的名称）：

print(os.path.isfile(r'\\DARAS-NAS\FORENSOR DTB Dataset processed\pow_day_125236_07.5.avi'))
print(os.path.isfile(r'\\DARAS-NAS\\FORENSOR DTB Dataset processed\\pow_day_125236_07.5.avi'))
print(os.path.isfile(r'\\\\DARAS-NAS\FORENSOR DTB Dataset processed\pow_day_125236_07.5.avi'))
print(os.path.isfile(r'\\\\DARAS-NAS\\FORENSOR DTB Dataset processed\\pow_day_125236_07.5.avi'))

Answer 1

也许这个工作：

def check(file):
    #try to open file
    try:
        open(file)
    except:
        #if file not exists return false becuse you cant open it
        return False
    else:
        #else return true
        True

只要调用它，file将是文件的路径和文件名
