如何将一个词典列表输出到Excel工作表？

Question

我有一个名为“玩家”的列表，其中包含词典。它看起来像这样：

players = [{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

它要长得多，但这是一段摘录。如何将这个词典列表输出到excel fils，以便按键/值整齐地组织？

非常感谢！

有一种方法可以将字典列表写入excel工作表。首先请确保您拥有XlsxWriter package。

from xlsxwriter import Workbook
players = [{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},            
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

ordered_list=["user","dailyWinners","dailyFree","bank"] #list object calls by index but dict object calls items randomly

wb=Workbook("New File.xlsx")
ws=wb.add_worksheet("New Sheet") #or leave it blank, default name is "Sheet 1"

first_row=0
for header in ordered_list:
    col=ordered_list.index(header) # we are keeping order.
    ws.write(first_row,col,header) # we have written first row which is the header of worksheet also.

row=1
for player in players:
    for _key,_value in player.items():
        col=ordered_list.index(_key)
        ws.write(row,col,_value)
    row+=1 #enter the next row
wb.close()

我尝试了代码，成功地工作了

<强> test.py

from csv import DictWriter

players = [{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},            
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

with open('spreadsheet.csv','w') as outfile:
    writer = DictWriter(outfile, ('dailyWinners','dailyFreePlayed','dailyFree','user','bank'))
    writer.writeheader()
    writer.writerows(players)

运行python test.py

然后在Excel中打开生成的spreadsheet.csv文件。

注意：我正在运行Linux，所以我无法使用Microsoft Excel进行测试。这适用于LibreOffice Calc，并提供一个电子表格，其中键是列名称，值在相应的列下。

使用pandas的解决方案

import pandas as pd

players = [{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
{'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},
{'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}]

df = pd.DataFrame.from_dict(players)

print (df)

df.to_excel('players.xlsx')

Answer 4

xlsxwriter库非常适合创建.xlsx文件（最初由Fatih1923提及）。

---

以下代码段根据字典列表生成.xlsx文件，同时说明顺序和显示的名称：

import xlsxwriter

# ...

def create_xlsx_file(file_path: str, headers: dict, items: list):
    with xlsxwriter.Workbook(file_path) as workbook:
        worksheet = workbook.add_worksheet()
        worksheet.write_row(row=0, col=0, data=headers.values())
        header_keys = list(headers.keys())
        for index, item in enumerate(items):
            row = map(lambda field_id: item.get(field_id, ''), header_keys)
            worksheet.write_row(row=index + 1, col=0, data=row)

用法

headers = {
    'bank': 'Money in Bank',
    'dailyWinners': 'Daily Winners',
    'dailyFree': 'Daily Free',
    'user': 'User',
}

players = [
    {'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player1', 'bank': 0.06},
    {'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player2', 'bank': 4.0},
    {'dailyWinners': 1, 'dailyFree': 2, 'user': 'Player3', 'bank': 3.1},
    {'dailyWinners': 3, 'dailyFree': 2, 'user': 'Player4', 'bank': 0.32}
]

create_xlsx_file("my xslx file.xlsx", headers, players)

?注意-headers字典表示顺序和显示的名称。如果您未使用Python3.6 +，请使用OrderedDict中的headers，因为dict中的顺序不会保留
