AttributeError:“非类型”对象没有属性“头”

Question

import pandas as pd    
from alpha_vantage.timeseries import TimeSeries
from alpha_vantage.techindicators import TechIndicators 
ts = TimeSeries(key=api_key, output_format = 'pandas')
ti = TechIndicators(key=api_key, output_format='pandas')
data1, meta_data1 = ts.get_intraday(symbol = 'GOOGL' ,interval = '5min', outputsize = 'full')
data2, meta_data2 = ti.get_bbands(symbol = 'GOOGL' , interval='5min', time_period=60)
data = pd.concat([data1, data2], axis=1, sort=False)
data = data.rename(columns={'1. open': 'Open', '2. high': 'High', '3. low': 'Low', '4. close': 'Close'}, inplace = True)
data.head()

在上面的代码中，我从alpha vantage api导入数据。但出现了上述错误。请帮帮我

Answer 1

当您使用inplace=True时，^{}函数就地执行操作，并且不返回具有重命名列的数据帧。相反，它返回None，然后将其分配给data，使其成为非类型对象。由于data不再是df，因此对其调用head()会导致出现错误
