如何从 python 的输出中获取特定部分

Question

我一直在尝试获取输出中的特定部分，但无法做到。

我使用的代码片段如下：

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，我得到如下输出：

我只要

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

然后我想比较if closeprice>open AND pCHange>1.5如果满足条件then

相同的对应输出应如下所示：

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

谁能帮我做同样的事情？提前致谢。

您从函数调用中获得的 return 值是一个字典。因此，您可以简单地遍历所有元素并使用以下代码打印它们的相应属性：

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"])
