It looks like you could just write as follows without using any
placeholder
number = text -> (pattern1 -> re.search)().group(0)\
-> (pattern2 -> re.search)().group(1)\
-> (pattern3 -> re.search)().group(0)\
-> float()
but anyway, a question seems:
once you start chaining applications of functions from the right,
might you start wanting assignment (expression) to the right (of an
object on the lhs to a variable on the rhs)?
I think that could be easier with chained applications from the right
for the reader of the code.
