我有一个大的csv文件,我想将其转换为包含相关信息的表。我会选择前五名来电者,然后在下面包含一些数据,例如最后一次通话说明,以及从该客户那里收到最多电话的人。

这是这样的:

我想创建一个表格,前五个来电者作为标题,位于EmpName(从该客户接听电话最多的人)下面,Gen_code和最近的一个句子(这些电话也有一个日期和时间收到列)CallDesc。

输出将像这张表一样布局(显然有不同的输入)

enter image description here

我很感激即使只是指导如何解决这个问题。伪代码很好。如果有一种快速,简单的方法,那就更好了!

到目前为止,我已对列表进行了排序,以便显示频率最高的客户位于列表的顶部。但是从那里我不知道如何获得最新的电话描述,甚至不知道如何选择前五名。

1 个答案:

答案 0 :(得分:0)

将表格读入pandas DataFrame:

import pandas as pd
filename = 'my_file.csv'
df = pd.read_csv(filename, sep=';')

创建数据透视表:雇主姓名与来电者姓名。

pivot = df.pivot_table(index='CallerName', columns='EmpName', values='ComplaintNumber', aggfunc='count')
# clean the table from NaNs (not necessary, but more beautiful):
pivot.fillna(0, inplace=True)

创建一个新的列总和并将每个调用者的总和保存到其中:

pivot['sum'] = pivot.sum(axis=1)

使用sum column descending对表进行排序:

pivot.sort('sum', ascending=False, inplace=True)

打印此表的前5个结果

print(pivot[:5])

我希望这就是你想要的!

编辑:您现在可以通过呼叫者对原始数据帧进行分组,只选择前5个并显示所需的所有信息。

EDIT2:“pivot [:5] .transpose()”会让你非常接近你建议的最终表格,其中前五名来电者是表格“标题”
