Python regex to match “spaced out” words

Question

When dealing with text files that have been produced using optical character recognition (OCR) I often come across lines or parts of lines

t h a t  a r e  s p a c e d  o u t  l i k e  t h i s.

I would like to be able to use a regular expression to match these words and smash the letters back together. But I have no idea how to do this using capture groups or my usual toolbox of regular expression knowledge.
