TypeError：+ 不支持的操作数类型：“_csv.reader”和“str”

            return 0 if checksum == 0 else 10 - checksum

res = luhn_calculate(f1_read)
res1= luhn_validate(f1_read)

print(res.partcode)

data = res.read()

file = open ("out.txt", "a+")
file.write(data.decode("utf-8") + "\n")
lst.append([str(sub_id),res.code])
df1 = pd.DataFrame(lst, columns=cols)
df1.to_excel("Output_1397.xlsx")     
print("DONE!")

在上面的程序中，由于错误而失败 类型错误：+ 不支持的操作数类型：“_csv.reader”和“str”

这里我们输入一个数字“893107032131149492”，不带校验位。我们需要输出作为校验位。 试图解决但仍然面临问题。

Answer 1

let
  Source = Folder.Files("C:\Mobility_reports_inputs_files"),
  #"Sorted Rows" = Table.Sort(Source,{{"Date modified", Order.Descending}}),
  #"Filtered Rows" = Table.SelectRows(#"Sorted Rows", each Text.StartsWith([Name], "Mob_repc", Comparer.OrdinalIgnoreCase) ),
  #"Kept First Rows" = Table.FirstN(#"Filtered Rows",1),
  Navigation1 = #"Kept First Rows"{0}[content]
in
  Navigation1

最后一步你想做什么？以上是我猜的。
