使用 Pandas 转换时值错误不匹配

Question

这是我不断收到的不匹配错误。我正在输入“202710”。

Traceback (most recent call last):
  File "nbastatsrecieveit.py", line 29, in <module>
    df.columns = headers

老实说，我不确定如何解决这个问题，因为它适用于特定玩家 ID，但不是所有玩家 ID。这是我的其余代码：

from nba_api.stats.endpoints import shotchartdetail
import pandas as pd
import json
from openpyxl import Workbook

print('Player ID?')
playerid = input()

filename = str(playerid) + '.xlsx'

response = shotchartdetail.ShotChartDetail(
    team_id= 0,
    context_measure_simple = 'FGA',
    #last_n_games = numGames,
    game_id_nullable = '0041900403',
    player_id= playerid
)

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 = pd.DataFrame(rows)
df.columns = headers

# write to excel file
df.to_excel(filename, index=False)

Answer 1

这是因为您的 df 的 ID 202710 为空。异常处理将解决这里的问题-

df = pd.DataFrame(rows)
try:
    df.columns = headers
except:
    pass
