bug in DataFrame/DataMatrix toCSV method when index=False

[changhiskhan]

When index=False an extra column is added because the leading comma is never removed.

def toCSV(self, path, nanRep='', cols=None, header=True, index=True, mode='wb'):

    *<snip>*

    for idx in self.index:

        if index:
            f.write(str(idx))
        for col in cols:
            *<snip>*
            f.write(',%s' % val)

what version of the code are you looking at? i think this got fixed on 3/15 which was post 0.3.0 release

    for idx in self.index:
        if index:
            f.write(str(idx))
        for i, col in enumerate(cols):
            val = series[col].get(idx)
            if isnull(val):
                val = nanRep
            else:
                val = str(val)

            if i > 0 or index:
                f.write(',%s' % val)
            else:
                f.write('%s' % val)

        f.write('\n')
