在循环中追加数据帧时列名是否重复？

Question

我有两个数据帧，我正在for循环中。当我试图附加两个Dataframes时，列名在行之间填充。 我做了一些研究并使用了列表，但我无法让列表对我起作用，这是我的代码

def generatesalesreport3():
if g_month is not None and g_year is not None:
    if (g_month == '1: January to March'):
        r_month = ['January','February','March']
        r_year = int(g_year)
    elif(g_month == '2: April to June'):
        r_month = ['April', 'May', 'June']
        r_year = int(g_year)
    elif(g_month == '3: July to Septempber'):
        r_month = ['July', 'August', 'September']
        r_year = int(g_year)
    else:
         r_month = ['October', 'November', 'December']
         r_year = int(g_year)

    ra = list()
    rb= list()
    for qmonth in r_month:
        monnum = month_dict[qmonth]
        resultb1 = df_b1.loc[(df_b1['month'] == monnum) & (df_b1['year'] == r_year)]
        resultb2 = df_b2.loc[(df_b2['month'] == monnum) & (df_b2['year'] == r_year)]
        resultb1 = resultb1.append(resultb2)
        print(resultb1)

所以，我的要求是，我不想让那些列名出现在结果中，然后我把完整的数据帧放到一个数据帧中，我必须基于模型列进行一些操作

只需从“resultb2”数据框中筛选出列，然后追加。比如：

resultb1 = resultb1.append(resultb2[["column1","column2","column3",......]])
print(resultb1)
