Append 字典由 python 转换为 EXCEL 文件

Question

This is my function, by using this i am trying to create(if file not exist) or append the dictionary into file.

headers = dict.keys()


if not os.path.isfile('metrics1.csv'):
    with open('metrics1.csv', 'w')as csv_file:
        csv_file.writelines(', '.join(headers))


if not os.path.isfile('metrics1.xlsx'):
    book = xlsxwriter.Workbook('metrics1.xlsx')
    sheet = book.add_worksheet("TestSheet")
    for (idx, header) in enumerate(headers):
        sheet.write(0, idx, header)
    book.close()


with open('metrics1.csv', 'a+') as csv_file:
    book = load_workbook('metrics1.xlsx')
    sheet = book.get_sheet_by_name('TestSheet')


    for d in dict:
        values = [d[key] for key in headers]
        csv_string = '\n'+', '.join(values)
        csv_file.write(csv_string)
        sheet.append(values)
    book.save(filename='metrics1.xlsx')

i got following error,

  values = [d[key] for key in headers]
  TypeError: string indices must be integers

Answer 1

You need to fix several things. First and foremost, do not name any variables dict . dict is a python built-in keyword. We'll assume that you've renamed it data in the code below.

Second, you can create your headers list a little more easily:

headers = list(data.keys())  #  or [ key for key in data ]

Third, and finally, is the line where you want to extract value from a dictionary:

values = [data[key] for key in headers]

Hope this helps!
