I don't know if this is as good as CSV's splitter, but it works
reasonably well for me:
import re
regex = re.compile(r'''
'.*?' | # single quoted substring
".*?" | # double quoted substring
\S+ # all the rest
''', re.VERBOSE)
print regex.findall('''
This is 'single "quoted" string'
followed by a "double 'quoted' string"
''')
