Question

我有2个表，其中有3行3列：

   Table 1                                 Table 2
 1   7    9                              1    4   7
 2   4   11                             12   -4  -1
 7   3    2                              2    4   11

我想将这两个表合并到一个数据框中并删除重复的行：

Expected Output (Table 3):
1    7   9
7    3   2
1    4   7
12  -4  -1

我也希望输出在excel中。 下面的代码有什么问题？：

 import pandas as pd
 import numpy as np

 df1 = pd.read_excel('Table 1.xlsx')
 df2 = pd.read_excel('Table 2.xlsx')

 frames = [df1,df2]
 result = pd.concat(frames)

 no_duplicates = result.drop_duplicates(False)

 import xlsxwriter
 workbook = xlsxwriter.Workbook('Table 3.xlsx', {'constant_memory': True})
 worksheet = workbook.add_worksheet()
 row = 0

for row, group in enumerate (no_duplicates):
 for col in range(3):
    worksheet.write (row, col, group[col])

workbook.close()

Answer 1

尝试以下代码

import pandas as pd
from pandas import ExcelWriter
df1=pd.DataFrame([[1,7,9],[2,4,11],[7,3,2]])
df2=pd.DataFrame([[1,4,7],[12,-4,-1],[2,4,11]])
df=pd.concat([df1,df2]).drop_duplicates().reset_index(drop=True)
wr = ExcelWriter('./sample.xlsx')
df.to_excel(wr,'Sheet5',index=False)
wr.save()
