python之文件路径截取 & endswith()

• 文件路径截取：

>>> import os
>>> path = '/etc/singfor/passwd/sunny/test.log'
>>>
>>> os.path.dirname(path)
'/etc/singfor/passwd/sunny'
>>>
>>> os.path.basename(path)
'test.log'

• endswith()：

>>> ret = []
>>> a
['changeID', 'projectID', 'groupID', 'list_1', 'sunny']
>>> for item in a:
...     if item.endswith("ID"):
...             ret.append(item)
...     else:
...             pass
...
>>> print ret
['changeID', 'projectID', 'groupID']
