python - 在循环中附加数据帧时列名会重复吗？

Question

我有两个数据帧，我正在将它们放入 for 循环中。当我尝试附加两个数据框时，列名将填充在行之间。我做了一些研究并使用了列表，但我无法使列表为我工作，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，我的要求是我不想在结果中获取这些列名称，之后我将完整的数据帧放入一个数据帧中，我必须根据模型进行一些操作> 栏目。

只需从“resultb2”数据框中过滤掉列，然后追加。喜欢:

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