Here's what I'm using to transform spaces to '_':

    path = string.translate(path, string.maketrans(' ', '_'))

This is only invoked on file upload.  If you're doing it a lot, I'd
just create the translation table once and stash it in a member
variable.

If you're doing this from DTML, the following untested code should be
a clue:

  <dtml-let table="_.string.maketrans(' ', '_')">
    ...
    <dtml-let fname="_.string.translate(name, table)">
      ...
    </dtml-let>
    ...
  </dtml-let>

Better check that maketrans and translate are in the version of the
string module available for DTML...

It'd be more like:
  <dtml-var "localfsObject[par1][par11]">

I.E. inside the quotes you're in Python and par1 and par11 are
assumed to be variable names.  The quotes would mean you were looking
for folders named "<dtml-var par1>", etc.  Note that you neither need
nor want a '.' between the subscripts.
