如何从我的python输出中获取特定部分

Question

我一直试图在输出中获得特定的部分，但无法做到。

我使用的代码片段如下所示：

from nsetools import Nse
nse = Nse()
print (nse)
q1 = nse.get_quote('canbk') # it's ok to use both upper or lower case for codes.
from pprint import pprint # just for neatness of display
pprint(q1)
q2 = nse.get_quote('sbin') # it's ok to use both upper or lower case for codes.
from pprint import pprint # just for neatness of display
pprint(q2)

对于上面的代码，我得到的输出如下：

我只想要

'closePrice': 127.4, 
'open': 126.95,
'pChange': 1.6,
'symbol': 'xxxx',

此外，如果closeprice>open和pCHange>1.5满足条件，那么我想比较

相同的对应输出应如下所示：

****** BUY **SYMBol name*********

有人能帮我做同样的事吗？提前谢谢。

从函数调用中获得的返回值是一个字典。因此，您可以使用以下代码简单地迭代所有元素并打印它们相应的属性：

from nsetools import Nse
nse = Nse()
print (nse)
q1 = nse.get_quote('canbk') # it's ok to use both upper or lower case for codes.
from pprint import pprint # just for neatness of display
# pprint(q1)
q2 = nse.get_quote('sbin') # it's ok to use both upper or lower case for codes.
from pprint import pprint # just for neatness of display
pprint(q2)
# Loop to print specific attributes
for i in range(len(q2)):
print("Printing for the item : ", i+1)
print("closePrice : ", q2["closePrice"])
print("open :", q2["open"])
print("pChange : ", q2["pChange"])
print("symbol : ", q2["symbol"])
print()

if(q2["closePrice"] > q2["open"] and q2["pCHange"]>1.5):
print("BUY", q2["symbol"])
