使用熊猫转换时的值错误不匹配

编程问答 2022-06-10

问题描述

这是我不断收到的不匹配错误。我输入的是“ 202710”。

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

说实话，我不确定该如何解决此问题，因为它适用于特定的玩​​家ID，但并非适用于所有情况。这是我其余的代码：

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)

解决方法

这是因为您的df的ID为202710为空。异常处理将在这里解决问题-

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