Err... Sorry, but something is not clear here. When you say "strip out",
you mean "get rid of", or "access to" ? For what I remember of basic,
I guess it's the second answer, so:
>>> fname = "AVC1030708.14"
>>> print fname[0]
A
>>> print fname[-1]
4
>>> print fname[2:4]
C1
>>> print fname[2:-4]
C103070
>>>
etc...
Also and while we're at it, you also have:
>>> fname.split('.')
['AVC1030708', '14']
>>> fname.split('.')[0]
'AVC1030708'
>>> fname.split('.')[1]
'14'
>>> fname.strip('4')
'AVC1030708.1'
>>> fname.strip('A')
'VC1030708.14'
>>> fname.lstrip('A')
'VC1030708.14'
>>> fname.rstrip('4')
'AVC1030708.1'
>>> fname.rstrip('41.')
'AVC1030708'
etc...
