我不知道如何让这段代码正常运行
df1 = pd.read_csv('TradeSheet2.csv', engine='python', sep=r'\s*,\s*', index_col='Symbol', header=0, encoding='ascii')
buy_sig = df1.loc[df1.Total >= 20]
sell_sig = df1.loc[df1.Total <= -20]
df2 = pd.read_csv('Header_Col.csv', index_col='Symbol')
def create_long():
global df2
dfnewlong = pd.concat([df2, buy_sig]).drop_duplicates(keep=False)
print(dfnewlong)
print(dfnewlong.index)
dfnewlong.set_index('Symbol', inplace=True, drop=False)
dfnewlong['DateTime'] = pd.to_datetime(dfnewlong['DateTime'])
dfnewlong['Long_Short'] = dfnewlong['Long_Short'].fillna('Long')
dfnewlong.Symbol = dfnewlong.Symbol.str.strip()
ticker = dfnewlong['Symbol']
livequote = si.get_live_price(ticker)
dfnewlong['Entry_Price'] = dfnewlong['Entry_Price'].fillna(livequote)
df2 = pd.concat([df2, dfnewlong])
print(df2.columns)
create_long()
我一直收到错误:“KeyError: "None of ['Symbol'] are in the columns
”
我试图实现的是函数将股票符号拉入变量,但它似乎不起作用,因为股票符号在索引列中

有什么建议吗
您需要首先调用
reset_index
,因为您已经将Symbol
设置为索引:此外,如果要取消将“Symbol”设置为索引列,还可以删除下一行(调用
set_index
)相关问题 更多 >
