Python仅使用xlwt / xlrd附加xls文件

Question

I am having problems appending issues appending data to an xls file. Long story short, I am using a program to get some data from something and writing it in an xls file.

If I run the script 10 times, I would like the results to be appended to the same xls file.

My problem is that I am forced to use Python 3.4 and xlutils is not supported, so I cannot use the copy function.

I just have to use xlwt / xlrd . Note, the file cannot be a xlsx .

Is there any way i can do this?

Answer 1

I would look into using openpyxl, which is supported by Python 3.4. An example of appending to a file can be found https://openpyxl.readthedocs.org/en/default/ . Please also see: How to append to an existing excel sheet with XLWT in Python . Here is an example that will do it. Assuming you have an Excel sheet called sample.xlsx:

from openpyxl import Workbook, load_workbook


# grab the active worksheet
wb = load_workbook("sample.xlsx")
ws = wb.active
ws.append([3])

# Save the file
wb.save("sample.xlsx")
