Python just uses the atof() function from the underlying C library.
Some of them handle NaN's, and some of them don't.

As a work around, how would I write this in list comprehension form:

         newlist=[]
         for i in range(len(v[1])):
            try:
               newlist.append(float(v[1][i]))
            except:
               newlist.append(-999.99) # or just nan possibly?

from numpy import nan

def nanfloat(x):
    if x.lower() == 'nan':
        return nan
    else:
        return float(x)

newlist = [myfloat(x) for x in v[1]]
