from a filename(str) extension or name

Project description


我絕對不要再為了這個坑花了整整2小時 Orz......

From a filename(str) get extension or name.

用法 how to use

get_filename( filename=str, mode='filename', index=0):

@param  {str} filename (不能為空)
@param  {str} mode ('filename' or 'extension') or ( 1 or 2)
@param  {int} index (當 mode = 'extension' 或 2 才會作用)
@return {str}

ex1 :

  t = get_filename('explosion.hard.txt')
  t -> 'explosion.hard'

ex2 :

t = get_filename('/path/to/somefile.ext')
t = 'somefile'

ex3 :

t = get_filename('explosion.hard.txt','extension',-3)
t = get_filename('explosion.hard.txt',2,0)
t -> 'explosion'

ex4 :

t = get_filename('/path/to/somefile.txt','extension',-1)
t = get_filename('/path/to/somefile.txt',2,-1)
t -> 'txt'
