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']
