Pandas：创建数据框时不按字母顺序自动排序列名

您可以将列的（正确排序的）列表作为参数传递给构造函数，或使用OrderedDict：

# option 1:result = pd.Dataframe({'date': datelist, 'total': [0]*len(datelist),         'TT': [0]*len(datelist)}, columns=['date', 'total', 'TT'])# option 2:od = collections.OrderedDict()od['date'] = datelistod['total'] = [0]*len(datelist)od['TT'] = [0]*len(datelist)result = pd.Dataframe(od)
