AttributeError: 'DataFrame' object has no attribute 'set_value'

[akitxu]

Thanks for sharing this work. I try to understand it by running some sscripts. In the script for calculating the 'Accumulation Distribution', it returns the error that I mention in the title.

`import pandas as pd
import yfinance as yf

Accumulation Distribution

def acc_dist(data, trend_periods=21, open_col='Open', high_col='High', low_col='Low', close_col='Close', vol_col='Volume'):
for index, row in data.iterrows():
if row[high_col] != row[low_col]:
ac = ((row[close_col] - row[low_col]) - (row[high_col] - row[close_col])) / (row[high_col] - row[low_col]) * row[vol_col]
else:
ac = 0
data.set_value(index, 'acc_dist', ac)
data['acc_dist_ema' + str(trend_periods)] = data['acc_dist'].ewm(ignore_na=False, min_periods=0, com=trend_periods, adjust=True).mean()

return data

n = 14
data = df = yf.download('AAPL', start= start_day, end = end_day)
data = acc_dist(df_val, trend_periods=21, open_col='Open>', high_col='High', low_col='Low', close_col=nom_val, vol_col='Volume')

`
Me devuelve,

`[100%**] 1 of 1 completed

What can be the cause?

It works by making the following change
data.loc[index, 'acc_dist' ] = ac #data.set_value(index, 'acc_dist', ac) # pone un unico valor en la columna y el índice que se pasan
