There are 3 lists: water = [1,2,3,4,2,4,2,4,5,2,3,4,2,1,3,4,3,2,5,1] nutri = [1,2,4,6,5,6,7,5,4,5,6,7,4,3,5,5,6,5,4,3,5] mineral =[2,1,1,3,2,4,2,4,5,4,3,2,3,2,3,1,3,4,5,1,4] add them to 3 separate columns of dataframe df, name the columns A, B, C

def add_columns(a, b, c):
  df['A'] = a
  df['B'] = b
  df['C'] = c
    
add_columns(water, nutri, mineral)
