1/read into CSV file: The Loadtxt function in NumPy can easily read the CSV file, automatically slice the fields, and load the data into the NumPy array

C,v=numpy.loadtxt (' data.csv ', delimiter= ', ', usecols= (6,7), unpack=true)

As you can see, the data is stored in the Data.txt file, and the delimiter is set to "," because a CSV file is to be processed. The Usecols parameter is a tuple that gets the data from the 7th field to the 8th field. The unpack parameter is set to True, which means that the data that stores different columns is separated, that is, the array of columns seventh/eighth is assigned to the variables C and v.
