Hi,

I have a function say

def excelsqrtfile(k):
  if(k>0):
    result = m.sqrt(x)
    print(result)
  else:
    result = 0
  return result

I need to apply this function to a specific column in Excel sheet.
I have a dataframe df

I am calling the function like below.

df1["sqr"]=excelsqrtfile(df1.dummy)

Error:
ValueError: The truth value of a Series is ambiguous. Use a.empty, a.bool(), a.item(), a.any() or a.all().

Any Help would be appreciated.

Thanks,
