The presense of a delimiter indicates that there is a field
both before and after the delimiter. If it didn't work that
way, then you'd get the same results for
input = "2b 3 4bx 5b 2c 4a 5a 6"
as you would for
input = "b 3 4bx 5b 2c 4a 5a 6"
you would get the same results for
input = "2222b22222"
as you would for
intput = "b"

projectOptions = (input.replace(" ", "")).split('2')
if projectOptions[0] == '':
del projectOptions[0]
print projectOptions
