str.strip() strange behavior

Question

>>> t1 = "abcd.org.gz"
>>> t1
\'abcd.org.gz\'
>>> t1.strip("g")
\'abcd.org.gz\'
>>> t1.strip("gz")
         


        

Answer 1

x.strip(y) will remove all characters that appear in y from the beginning and end of x.

That means

'foo42'.strip('1234567890') == 'foo'

becuase '4' and '2' both appear in '1234567890'.

Use os.path.splitext if you want to remove the file extension.

>>> import os.path
>>> t1 = "abcd.org.gz"
>>> os.path.splitext(t1)
('abcd.org', '.gz')
