Concatenate certain letters in a string

I have been using this stackoverflow for years, but have never posted questions personally. I hope my first question is not too naive.

I am trying to do some concatenation in a string. Let's say I have a string

string = "C S E majors in U S"

I want to make this string that looks something like

string = "CSE majors in US"

I thought about doing it by splitting the string into list, loop it, and check whether the element has a length equals to 1. If it has, check for next ones iteratively, and combine them at the end.

I was wondering whether there are better approaches to this. Since I am pretty new to python, it will be very nice to have some illustrations with codes.

Thanks in advance!

Nope.

>>> ' '.join((' ' if pred else '').join(seq) for pred, seq in itertools.groupby("C S E majors in U S".split(), lambda x: len(x) > 1))
'CSE majors in US'
