Question

环境：飞索1.3.0 迷你康达3 Windows OS

我正在尝试对数据进行S迭代。 S.symbol具有15个值。

在1个符号的数据中进行迭代时，请按以下代码说“间谍”；我想创建2个钥匙

（S.symbol +“ c”）-> spyc保持当前值

（S.symbol +“ s”）—→监视以保留浮点值。

def before_trading_start(context,data):
print("*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#")
print("Get DateTime: ",get_datetime())
#context is a dictionary
for S in data:
    if(S.symbol == 'SPY'):
        arr = list(range(1,91))
        hist = data.history(S,"price",90,"1d")
        price_list = np.log(hist.tolist())
        context.spyc = data.current(S,"price")
        context.spys = Slope(arr, price_list)
        print (context.spyc)
        print (S.symbol, context.spys)


    else:
        continue

################我的动态命名版本失败

def before_trading_start(context,data):
print("*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*")
print("Get DateTime: ",get_datetime())
for S in data:
    arr = list(range(1,91))
    hist = data.history(S,"price",90,"1d")
    price_list = np.log(hist.tolist())

    context[S.symbol + "c"] = data.current(S,"price")
    context[S.symbol+"s"] = Slope(arr, price_list)
    print (context[S.symbol + "c"])
    print (S.symbol, context[S.symbol + "s"])

S.symbols = [“间谍”，“ AAPl”，'xom'，'L'，'T'，'CSCO'，'MSFT'..]

如何在Python中的字典中分配动态键值？
