python读取配置文件不更改大小写_Python不区分大小写的文件名？

如果不列出一个目录，并将要查找的项和目录中的每个项都转换为一个常见的案例进行比较，则无法执行此操作。文件系统是区分大小写的，这就是它的全部功能。def path_insensitive(path):

"""

Get a case-insensitive path for use on a case sensitive system.

>>> path_insensitive('/Home')

'/home'

>>> path_insensitive('/Home/chris')

'/home/chris'

>>> path_insensitive('/HoME/CHris/')

'/home/chris/'

>>> path_insensitive('/home/CHRIS')

'/home/chris'

>>> path_insensitive('/Home/CHRIS/.gtk-bookmarks')

'/home/chris/.gtk-bookmarks'

>>> path_insensitive('/home/chris/.GTK-bookmarks')

'/home/chris/.gtk-bookmarks'

>>> path_insensitive('/HOME/Chris/.GTK-bookmarks')

'/home/chris/.gtk-bookmarks'

>>> path_insensitive("/HOME/Chris/I HOPE this doesn't exist")

"/HOME/Chris/I HOPE this doesn't exist"

"""

return _path_insensitive(path) or path

def _path_insensitive(path):

Recursive part of path_insensitive to do the work.

if path == '' or os.path.exists(path):

return path

base = os.path.basename(path) # may be a directory or a file

dirname = os.path.dirname(dirname)

if not os.path.exists(dirname):

dirname = _path_insensitive(dirname)

if not dirname:

return

# at this point, the directory exists but not the file
