回答by Avión
Change receipt.write(output_to_receipt)to receipt.write(str(output_to_receipt)).
更改receipt.write(output_to_receipt)为 receipt.write(str(output_to_receipt))。
This will change output_to_receiptwhich is a tuple to an string and you'll be able to write.
这将更改output_to_receipt哪个是字符串的元组，您将能够编写。
回答by Sven Hakvoort
output_to_receipt is a tuple, so you need to convert it to a string with str(output_to_receipt)or "".join(output_to_receipt)for example.
output_to_receipt是一个元组，所以你需要将它与转换为字符串str(output_to_receipt)或"".join(output_to_receipt)为例子。
