python去除扩展名

import os

printos.path.splitext("path_to_file")[0]

from os.path import basename

# now you can call it directly with basename

print basename("/a/b/c.txt")

>>>base=os.path.basename('/root/dir/sub/file.ext')

>>> base

'file.ext'

>>> os.path.splitext(base)

('file', '.ext')

>>> os.path.splitext(base)[0]

'file'

>>>

>>> printos.path.splitext(os.path.basename("hemanth.txt"))[0]

hemanth

>>> file ='/root/dir/sub.exten/file.data.1.2.dat'

>>> print('.').join(file.split('.')[:-1])

/root/dir/sub.exten/file.data.1.2

>>> s = 'c:\\temp\\akarmi.txt'

>>> print(os.path.splitext(s)[0])

c:\temp\akarmi

因此，我不需要驱动器号或者目录名，我使用：

>>>print(os.path.splitext(os.path.basename(s))[0])

akarmi

def getFileNameWithoutExtension(path):

 returnpath.split('\\').pop().split('/').pop().rsplit('.', 1)[0]

getFileNameWithoutExtension('/path/to/file-0.0.1.ext')

# => file-0.0.1

getFileNameWithoutExtension('\\path\\to\\file-0.0.1.ext')

# => file-0.0.1
