当使用此代码将video上传到YouTube时，获得命名的标题末尾具有文件扩展名（在本例中为.mp4）
for %%f in (*.mp4) do python --file="%%f" --title="%%f" for %%f in (*.csv) do echo "%%~nf"使用for %%f in (*.csv) do echo "%%~nf"
为更多的信息做一个for /? ..这是你会看到的部分
In addition, substitution of FOR variable references has been enhanced. You can now use the following optional syntax: %~I - expands %I removing any surrounding quotes (") %~fI - expands %I to a fully qualified path name %~dI - expands %I to a drive letter only %~pI - expands %I to a path only %~nI - expands %I to a file name only %~xI - expands %I to a file extension only %~sI - expanded path contains short names only %~aI - expands %I to file attributes of file %~tI - expands %I to date/time of file %~zI - expands %I to size of file %~$PATH:I - searches the directories listed in the PATH environment variable and expands %I to the fully qualified name of the first one found. If the environment variable name is not defined or the file is not found by the search, then this modifier expands to the empty string
