问题描述
我正在使用熊猫将NBA API JSON格式转换为csv，并且出现回溯错误。现在，我会注意到几天前我遇到了另一个回溯错误，但这是不同的。
这个错误让我很困扰，特别是因为相同的代码在程序的早期工作。这是控制台中的错误： 追溯（最近一次通话）：
File "nbagamestats.py",line 48,in <module>
dfLoop.columns = headersLoop
File "C:\Users\*\AppData\Local\Packages\PythonSoftwareFoundation.Python.3.8_qbz5n2kfra8p0\LocalCache\local-packages\python38\site-packages\pandas\core\generic.py",line 5149,in __setattr__

raise ValueError(
ValueError: Length mismatch: Expected axis has 0 elements,new values have 24 elements
此外，这是我编写的所有代码：
from nba_api.stats.endpoints import BoxscoreTraditionalv2
from nba_api.stats.endpoints import shotchartdetail
import pandas as pd
import json
from openpyxl import Workbook
print('Game ID?')
gamenum = input()
### PART ONE - Player List###
response = BoxscoreTraditionalv2.BoxscoreTraditionalV2(
end_period = 0,game_id= gamenum
)
content = json.loads(response.get_json())
# transform contents into dataframe
results = content['resultSets'][0]
headers = results['headers']
rows = results['rowSet']
df = pd.DataFrame(rows)
df.columns = headers
playerList = df['PLAYER_ID'].tolist()
print(playerList)
###PART TWO - Download Player Shotchart Data###
for i in playerList :
filename = str(i) +'.xlsx'
responseLoop = shotchartdetail.ShotChartDetail(
team_id= 0,#last_n_games = numGames,game_id_nullable = gamenum,player_id= i
)
contentLoop = json.loads(responseLoop.get_json())
# transform contents into dataframe
resultsLoop = contentLoop['resultSets'][0]
headersLoop = resultsLoop['headers']
rowsLoop = resultsLoop['rowSet']
dfLoop = pd.DataFrame(rowsLoop)
dfLoop.columns = headersLoop
# write to excel file
dfLoop.to_excel(filename,index=False)
print(i + ' has been written')
希望您能提供帮助，谢谢。
解决方法
好吧，是的，要进入季后赛，您需要在该处添加该参数（或者我应该说是将其更改为默认值"Regular Season"。该流程图仅返回Made Shot，而不是错过的快照） （同样是默认设置）。因此，如果您想进行所有射击尝试，则还需要更改另一个参数：
from nba_api.stats.endpoints import boxscoretraditionalv2
from nba_api.stats.endpoints import shotchartdetail
import pandas as pd
import json
from openpyxl import Workbook
#print('Game ID?')
#gamenum = input()
gamenum = '0041900404'
### PART ONE - Player List###
response = boxscoretraditionalv2.BoxScoreTraditionalV2(
end_period = 0,game_id= gamenum
)
content = json.loads(response.get_json())
# transform contents into dataframe
results = content['resultSets'][0]
headers = results['headers']
rows = results['rowSet']
df = pd.DataFrame(rows,columns=headers)
playerList = df['PLAYER_ID'].tolist()
print(playerList)
###PART TWO - Download Player Shotchart Data###
for i in playerList :
filename = str(i) +'.xlsx'
responseLoop = shotchartdetail.ShotChartDetail(
team_id= 0,season_type_all_star = 'Playoffs',#<-- change to 'Playoffs' - default is 'Regular Season' I believe
context_measure_simple = 'FGA',#<-- Default is 'PTS' and will only return made shots
game_id_nullable = gamenum,player_id= i
)
contentLoop = json.loads(responseLoop.get_json())
# transform contents into dataframe
resultsLoop = contentLoop['resultSets'][0]
headersLoop = resultsLoop['headers']
rowsLoop = resultsLoop['rowSet']
dfLoop = pd.DataFrame(rowsLoop,columns=headersLoop)
# write to excel file
dfLoop.to_excel(filename,index=False)
print(str(i) + ' has been written')
输出示例：
print(dfLoop.to_string())
