How to remove spaces with Calculate field in ArcMap?

[LianaSmith]

My values are padded with spaces. Sometimes it's "1", sometimes it's " 1" sometimes its "1  ".

I need to remove all the spaces before, between, after, wherever they appear...

Thanks!!!!

the method of parsing the data isn't clear... here is an example that can result in zeros before and after.

Just call it ... to bee or not to bee...

>>> bee = "B"

>>> "{!s:>04}".format(bee)

'000B'

>>> "{!s:<04}".format(bee)

'B000'

So the parser also needs to be clarified
