如何将字典列表输出到Excel表格？

Question

我有一个叫做'players'的列表，这个列表里面装的是一些字典。它的样子是这样的：

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}]

这个列表其实还很长，但我只截取了一部分。请问我该怎么把这个字典列表输出到一个Excel文件里，让它按键值对整齐地排列呢？

有一种方法可以把字典列表写入Excel工作表。首先，确保你已经安装了XlsxWriter包。

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 the dict object calls items randomly

wb=Workbook("New File.xlsx")
ws=wb.add_worksheet("New Sheet") # Or leave it blank. The 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()

我试过这个代码，它成功运行了。

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, 'dailyFreePlayed': 2, 'user': 'Player3', 'bank': 3.1},
{'dailyWinners': 3, 'dailyFreePlayed': 2, 'user': 'Player4', 'bank': 0.32}]

df = pd.DataFrame.from_dict(players)

print (df)

df.to_excel('players.xlsx')

Answer 3

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：我在使用Linux，所以没法用Microsoft Excel测试这个。不过在LibreOffice Calc中可以正常运行，生成的表格里，键会作为列名，值会在对应的列下。
