11 ### START CODE HERE
12 # Load the temperatures using np.loadtxt. Remember you want to skip the first
13 # row, since it’s headers. Make sure to use the correct column of the csv file.
—> 14 next(filename)
15 temperatures = np.loadtxt(float(filename[2]))
16 times = np.loadtxt(int(filename[0])) # Create the time steps.

TypeError: ‘str’ object is not an iterator

Hi @Shantanu7

This error tells you that you’re trying to use next() on a string object, but you must use it on an iterator. Here, filename is a string representing the path to your CSV file, but next(filename) assumes that filename is an iterator, which it is not.

Try opening the file first.

Hope it helps!
