Python 将1个文件夹移回后创建新文件夹
嗨,我有一条老路:Python 将1个文件夹移回后创建新文件夹,python,os.path,Python,Os.path,嗨,我有一条老路: OldPath = "C:\\Desktop\\Outerfolder\\InnerFolder" 并使用以下代码片段: os.path.normpath(OldPath + os.sep + os.pardir NewFolder = os.path.join(os.path.normpath(OldPath + os.sep + os.pardir),"\\NewInnerFolder") print NewFolder 我得到C:\Desktop\Outerfol
OldPath = "C:\\Desktop\\Outerfolder\\InnerFolder"
并使用以下代码片段:
os.path.normpath(OldPath + os.sep + os.pardir
NewFolder = os.path.join(os.path.normpath(OldPath + os.sep + os.pardir),"\\NewInnerFolder")
print NewFolder
我得到C:\Desktop\Outerfolder
但在另一段代码中使用它:
os.path.normpath(OldPath + os.sep + os.pardir
NewFolder = os.path.join(os.path.normpath(OldPath + os.sep + os.pardir),"\\NewInnerFolder")
print NewFolder
我只得到:
\NewInnerFolder
为什么会这样?也许你应该像下面这样写,不带“/”
NewFolder = os.path.join(os.path.normpath(OldPath + os.sep + os.pardir),"NewInnerFolder")
print NewFolder
当您传递“//NewInnerFolder”时,os.path.join会将其视为“绝对路径”,并将其加入驱动器路径
这是python 3.5中os.path.join的源代码:
def join(path, *paths):
if isinstance(path, bytes):
sep = b'\\'
seps = b'\\/'
colon = b':'
else:
sep = '\\'
seps = '\\/'
colon = ':'
try:
if not paths:
path[:0] + sep #23780: Ensure compatible data type even if p is null.
result_drive, result_path = splitdrive(path)
for p in paths:
p_drive, p_path = splitdrive(p)
if p_path and p_path[0] in seps:
# Second path is absolute
if p_drive or not result_drive:
result_drive = p_drive
result_path = p_path
continue
elif p_drive and p_drive != result_drive:
if p_drive.lower() != result_drive.lower():
# Different drives => ignore the first path entirely
result_drive = p_drive
result_path = p_path
continue
# Same drive in different case
result_drive = p_drive
# Second path is relative to the first
if result_path and result_path[-1] not in seps:
result_path = result_path + sep
result_path = result_path + p_path
## add separator between UNC and non-absolute path
if (result_path and result_path[0] not in seps and
result_drive and result_drive[-1:] != colon):
return result_drive + sep + result_path
return result_drive + result_path
except (TypeError, AttributeError, BytesWarning):
genericpath._check_arg_types('join', path, *paths)
raise

是的,你说得对。谢谢这给我留了一个变量名是的,你说得对。谢谢这将为我保存1个变量名
