strings

[Egor Bolonev]

Hi All!

I have a
'Pink Floyd/x00/x00/x00/x00/x00/x00/x00/x00/x00/x00/x00/x00'
and I want a
'Pink Floyd'
How can I manage it?

This one isn't work.
author=f.read(30).replace('\0',' ').rstrip() #from mp3 tag

Trick question ;-)

>>> pf = 'Pink Floyd/x00/x00/x00/x00/x00/x00/x00/x00/x00/x00/x00/x00'
>>> pf[f.index('/x00')] 'Pink Floyd'
>>> list(pf)

['P', 'i', 'n', 'k', ' ', 'F', 'l', 'o', 'y', 'd', '/', 'x', '0', '0', '/', 'x', '0', '0', '/',
'x', '0', '0', '/', 'x', '0', '0', '/', 'x', '0', '0', '/', 'x', '0', '0', '/', 'x', '0', '0', '
/', 'x', '0', '0', '/', 'x', '0', '0', '/', 'x', '0', '0', '/', 'x', '0', '0', '/', 'x', '0', '0
']

I.e., '/x00' is not '\x00' ;-)

If you are playing around with various methods, don't forget
to f.seek(0) between (assuming what you have is at the beginning of the file).

Yes it's weird. The Interactive window of PythonWin shows it correct, but
debugger window is not.:-(

Did you try it with a fixed string like a above?

BTW, a.replace('\0','') should work without creating and then stripping spaces, I think.
also a.rstrip('\0') -- though the meanings of all these are different if \x00 occurs internally,
not just in the tail.
