Method Details

[hide private]

getitem(self, index)
(Indexing operator)

source code

Allows indexing to get the bounds of this interval

I['lo'] or I[0] returns the low bound of I; I['hi'] or I[1] returns its high bound

setitem(self, index, value)
(Index assignment operator)

source code

Allows indexing to set the bounds of this interval

I['lo']= or I[0]= sets the low bound of I; I['hi']= or I[1]= sets its high bound
