我有一个具有播放器结构的json文件
[
{
"Player_Name": "Rory McIlroy",
"Tournament": [
{
"Name": "Arnold Palmer Invitational presented by Mastercard",
"Points": "68.10",
"Salary": "12200.00"
},
{
"Name": "World Golf Championships-Mexico Championship",
"Points": "103.30",
"Salary": "12200.00"
},
{
"Name": "The Genesis Invitational",
"Points": "88.60",
"Salary": "12200.00"
},
{
"Name": "Farmers Insurance Open",
"Points": "107.30",
"Salary": "12200.00"
},
{
"Name": "World Golf Championships-HSBC Champions",
"Points": "138.70",
"Salary": "12400.00"
},
{
"Name": "The ZOZO Championship",
"Points": "103.40",
"Salary": "12300.00"
}
]
}]
当我运行这段代码
import json
import numpy as np
import pandas as pd
from itertools import groupby
# using json open the player objects file and set it equal to data
with open('Active_PGA_Player_Objects.json') as json_file:
data = json.load(json_file)
with open('Players_DK.json') as json_file:
Players_DK = json.load(json_file)
results = []
for k,g in groupby(sorted(data, key=lambda x:x['Player_Name']), lambda x:x['Player_Name']):
results.append({'Player_Name':k, 'Tournament':[i['Tournament'][0] for i in g]})
for obj in results:
for x in Players_DK:
if obj['Player_Name'] == x['Name']:
obj['Average'] = x['AvgPointsPerGame']
i = 0
points_results = []
while i < len(results):
j = 0
while j < len(results[i]['Tournament']):
difference = (int(float(results[i]['Tournament'][j]['Points'])) - (results[i]['Average']))
points_results.append(round(difference,2))
j += 1
i += 1
with open('PGA_Player_Objects_w_Average.json', 'w') as my_file:
json.dump(results, my_file)
我的清单像这样回来
[{
"Player_Name": "Rory McIlroy",
"Tournament": [
{
"Name": "Arnold Palmer Invitational presented by Mastercard",
"Points": "68.10",
"Salary": "12200.00"
}
],
"Average": 96.19
}]
有人可以向我解释为什么更新我的特定词典时,它会从嵌套Tournament
列表中删除除第一个值以外的所有值吗?我在这里的目标是将每个玩家的平均值添加到其相应的词典中,以便我可以将每个平均值从每个分数中减去。当我尝试执行此操作时,我只能对列表中剩下的一个值执行操作。
仅仅为了它的价值,我会回过头来真正考虑每条线的实际作用。您还可以通过调用obj
或来使事情变得更加艰难x
。计算平均值可以像这样完成:
for player in data: # data is poorly named, try players or players_data
player['Average'] = sum(float(tourny['Points']) for tourny in player['Tournament']) / len(player['Tournament'])
for tourny in player['Tournament']:
tourny['Difference'] = float(tourny['Points']) - float(player['Average'])
给你留下:
{'Player_Name': 'Rory McIlroy',
'Tournament': [{
'Name': 'Arnold Palmer Invitational presented by Mastercard',
'Points': '68.10',
'Salary': '12200.00',
'Difference': -33.46666666666667},
{
'Name': 'World Golf Championships-Mexico Championship',
'Points': '103.30',
'Salary': '12200.00',
'Difference': 1.7333333333333343}, # .....etc
'Average': 101.566666666666666
}
当您在代码中使用名称描述它们所代表的内容时,大量的优化立即显而易见。搏一搏!
