I have a function here:
def ROC(dfH, n):
M = dfH['Close'].diff(n - 1)
N = dfH['Close'].shift(n - 1)
ROC = pd.Series(M / N, name = 'ROC_' + str(n))
dfH = dfH.join(ROC)
return dfH
With the above function I want to make multiple columns by changing the value of n so i run the code
a = (4, 8)
for j in a:
ROC(dfH, n=a)
which gets to be wrong. please help thanks in advance.
`
a = (4, 8)
for j in a:
ROC(dfH, n=a)
^
You are using a instead of j in the for loop.
