Python ntpath 模块，exists() 实例源码
我们从Python开源项目中，提取了以下50个代码示例，用于说明如何使用ntpath.exists()。
def makedirs(name, mode=0777):
"""makedirs(path [,mode=0777])
Super-mkdir; create a leaf directory and all intermediate ones.
Works like mkdir,except that any intermediate path segment (not
just the rightmost) will be created if it does not exist. This is
recursive.
"""
head, tail = path.split(name)
if not tail:
head, tail = path.split(head)
if head and tail and not path.exists(head):
try:
makedirs(head, mode)
except OSError, e:
# be happy if someone already created the path
if e.errno != errno.EEXIST:
raise
if tail == curdir: # xxx/newdir/. exists if xxx/newdir exists
return
mkdir(name, mode)
def renames(old, new):
"""renames(old,new)
Super-rename; create directories as necessary and delete any left
empty. Works like rename,except creation of any intermediate
directories needed to make the new pathname good is attempted
first. After the rename,directories corresponding to rightmost
path segments of the old name will be pruned until either the
whole path is consumed or a nonempty directory is found.
Note: this function can fail with the new directory structure made
if you lack permissions needed to unlink the leaf directory or
file.

def renames(old,directories corresponding to rightmost
path segments of the old name will be pruned way until either the

if you lack permissions needed to unlink the leaf directory or
file.
