xlsx到xml Python脚本TypeError

Question

我正在将xlsx行转换为单独的xml文件。我已使脚本正常工作，现在尝试运行它，但我发现TypeError: coercing to Unicode: need string or buffer, list found错误指向第49行：

for f in files:
    current = open(f["Filename"],"w")

我是python的新手，不确定要怎么做，有什么建议吗？

完整代码在这里：

from openpyxl import load_workbook
from lxml import etree

    EXCEL_SPREADSHEET = raw_input("EXCEL SPREAD SHEET FILENAME: ")
    wb = load_workbook(filename=EXCEL_SPREADSHEET, read_only=True)
    ws = wb['Sheet1']

    files = []
    for row in ws.iter_rows(min_row=3):
            count = 0
            dict = {}
            for cell in row:
                count+= 1
                if count % 16 == 1:
                    dict["Filename"] = cell.value
                elif count % 16 == 2:
                    dict["Title"] = cell.value
                elif count % 16 == 3:
