Solve the following python programming problem given the following code:
def _read_coil_def_file(fname) : 
    'Helper to read a coil def file' 
    big_val = 0.5 
    coils = list () 
    with open (fname, 'r') as fid : 
        lines = fid.readlines () 
lines = lines [: : (- 1)] 
    while (len (lines) > 0) : 
        line = lines.pop () 
        if (line [0] != '#') : 
            vals = np.fromstring (npts, sep = ' ') 
            assert (len (vals) in (6, 7)) 
            start = line.find ('"') 
            end = (len (line.strip ()) - 1) 
            assert (line.strip () [end] == '"') 
            desc = line [start : end] 
            npts = int (vals [3]) 
            coil = dict (coil_type = vals [1], coil_class = vals [0], desc = desc, accuracy = vals [2], size = vals [4], base = vals [5]) 
            rmag = list () 
            cosmag = list () 
            w = list () 
            for p in range (npts) : 
                line = lines.pop () 
                while (line [0] == '#') : 
                    line = lines.pop () 
vals = np.fromstring (line, sep = ' ') 
                assert (len (vals) == 7) 
                w.append (vals [0]) 
                rmag.append (vals [[1, 2, 3]]) 
                cosmag.append (vals [[4, 5, 6]]) 
w = np.array (w) 
            rmag = np.array (rmag) 
            cosmag = np.array (cosmag) 
            size = np.sqrt (np.sum ((cosmag ** 2), axis = 1)) 
            if np.any ((np.sqrt (np.sum ((rmag ** 2), axis = 1)) > big_val)) : 
                raise RuntimeError ('Unreasonable integration point') 
if np.any ((size <= 0)) : 
                raise RuntimeError ('Unreasonable normal') 
cosmag /= size [:, np.newaxis] 
            coil.update (dict (w = w, cosmag = cosmag, rmag = rmag)) 
            coils.append (coil) 
logger.info ('%d coil definitions read', len (coils)) 
    return coils 

    
    

    Fix the buggy line: vals = np.fromstring (npts, sep = ' ')
assistant
#Here is Python program to find ('"') 
.

vals = np.fromstring (line, sep = ' ')
