使用Python将单元格范围从Excel复制到另一个

如何解决使用Python将单元格范围从Excel复制到另一个

我想将一系列单元格从一个Excel文件复制到另一个（在Copying Data into Excel找到一个示例，并根据需要对其进行了修改），但收到一条错误消息（如下所示）。数据已复制到目标文件，但无法保存并关闭文件。 我试图创建，重命名以及删除save_file，但这无济于事。 我在这里想念什么？

import win32com.client as win32


# Define the full path for the data file file
data_file = "C:/2020/data.xlsx"

# Define the full path for the final output file
save_file = "C:/2020/result.xlsx"

# Define the template file
template_file = "C:/2020/template.xlsx"


# Use com to copy the files around
excel = win32.gencache.EnsureDispatch('Excel.Application')
excel.Visible = False
excel.DisplayAlerts = False


# Template file
wb_template = excel.Workbooks.Open(template_file)

# Open up the data file
wb_data = excel.Workbooks.Open(data_file)

# Copy from the data file (select all data in V2:V22 columns)
wb_data.Worksheets("Sheet1").Range("V2:V22").Select()

# Paste into the template file
excel.Selection.Copy(Destination=wb_template.Worksheets("Sheet2").Range("C7"))

# Must convert the path file object to a string for the save to work
wb_template.SaveAs(str(save_file))


wb_template.Close()
wb_data.Close()
excel.DisplayAlerts = True
excel.Quit()`

错误消息：

com_error                                 Traceback (most recent call last)

解决方法

将save_file = "C:/2020/result.xlsx"更改为save_file = "C:\\2020\\result.xlsx"
