用python实现一个excel数据透视表

Question

几天来，我一直在尝试使用不同的库在我的 Mac 操作系统上实现一个数据透视表，并最终使用了 xlwings，因为它看起来支持它。我主要在 Windows 上看到示例，但在 Mac 上看不到。经过一些研究，我得到了下面的代码，但它在这一行崩溃了

pivot_table = pivot_sheet.api.create_pivot_table(table_destination=pivot_range.api, read_data=data_range.api, table_name='MyPivotTable')

。我是这方面的新手，所以我可能做错了或者使用了错误的 mac 语法。贝娄也是我得到的错误。

我本可以使用 pandas，但保存到 excel 文件时它看起来并不像数据透视表。我需要一个可以让我添加行、列、过滤器和值字段的工具。

这个 github 文件 我发现有 mac os 语法，这与 windows 不同

任何帮助将不胜感激

import xlwings as xw
from xlwings import constants

# Open the workbook
wb = xw.Book('test_excel.xlsx')

# Select the data range
data_range = wb.sheets['Sheet1'].range('A1:C6')

# Create the pivot table
pivot_sheet = wb.sheets.add(name='PivotT')
pivot_range = pivot_sheet.range('A1')

print(pivot_range.api)
print(data_range.api)
pivot_table = pivot_sheet.api.create_pivot_table(table_destination=pivot_range.api, read_data=data_range.api, table_name='MyPivotTable')

# Add the fields

# structure the pivot table
pivot_table.pivot_fields('Name').orientation = constants.PivotFieldOrientation.xlRowField
pivot_table.pivot_fields('Gender').orientation = constants.PivotFieldOrientation.xlPageField
pivot_table.pivot_fields('Age').orientation = constants.PivotFieldOrientation.xlColumnField

DataField = pivot_table.add_data_field(pivot_table.pivot_fields('Age'))
DataField.Function = constants.TotalsCalculation.xlTotalsCalculationSum

# Save and close the workbook
wb.save()
wb.close()

Answer 1

应该能够做类似下面的事情；
这为我运行了宏；
宏在创建 Pivot 缓存时出错，我没有深入研究原因，但工作表已打开，

macro1

保存在

Module1

中开始运行。
另一个注意事项，启用宏的 Excel 书籍需要另存为

.xlsm

所以我希望您打开的文件是

test_pt.xlsm

而不是

test_pt.xlsx

.

import xlwings as xw


path = 'test_pt.xlsm'

with xw.App(visible=True) as app:
    wb = xw.Book(path)
    ExcelMacro = wb.macro('macro1')
    ExcelMacro()
