You're missing the append call after the break line.

But otherwise, it's obvious that not doing the double
lookup would be faster.

It's more readable, yes, but actual speed differences
would be barely noticeable (both __contains__, index
and find use the same code in CPython).

This is still doing a double lookup of '-' on the
string. Best to split it in two.

i = ndata.find('-')
if i != -1 and ndata[i-1] in ' ,e':
