'list','_AtIndexer' object is not callable PandaPy
Question:
mp = pd.read_csv("Stock price over the last 24 months of Adidas, Nike, and Puma.csv",index_col=0)
mr = pd.DataFrame()
# compute monthly returns
for s in mp.columns:
date = mp.index[0]
pr0 = mp[s][date]
for t in range(1,len(mp.index)):
date = mp.index[t]
pr1 = mp[s][date]
ret = (pr1-pr0)/pr0
mr.set_value(date,s,ret)
pr0 = pr1
I try to predict the Stock price over the last 24 months of Adidas, Nike, and Puma buy using panda and I’m get error
TypeError Traceback (most recent call last)
Input In [60], in <cell line: 3>()
8 pr1 = mp[s][date]
9 ret = (pr1-pr0)/pr0
---> 10 mr.set_value(date,s,ret)
11 pr0 = pr1
TypeError: 'list' object is not callable
PS: I try to solve by reading same error but i can’t solve this.
trying to use mr.at instead of set_value and i got another error
TypeError Traceback (most recent call last)
Input In [3], in <cell line: 5>()
10 pr1 = mp[s][date]
11 ret = (pr1-pr0)/pr0
---> 12 mr.at(date,s,ret)
13 pr0 = pr1
TypeError: '_AtIndexer' object is not callable
please help
Answers:
you should use .at like this:
mr.at[date,s]=ret
full code:
mp = pd.read_csv("Stock price over the last 24 months of Adidas, Nike, and Puma.csv",index_col=0)
mr = pd.DataFrame()
# compute monthly returns
for s in mp.columns:
date = mp.index[0]
pr0 = mp[s][date]
for t in range(1,len(mp.index)):
date = mp.index[t]
pr1 = mp[s][date]
ret = (pr1-pr0)/pr0
mr.at[date,s]=ret
pr0 = pr1
mp = pd.read_csv("Stock price over the last 24 months of Adidas, Nike, and Puma.csv",index_col=0) mr = pd.DataFrame() # compute monthly returns for s in mp.columns: date = mp.index[0] pr0 = mp[s][date] for t in range(1,len(mp.index)): date = mp.index[t] pr1 = mp[s][date] ret = (pr1-pr0)/pr0 mr.set_value(date,s,ret) pr0 = pr1
