Numpy.genfromtxt() and numpy.loadtxt(). But have you ever thought about loading the data into numpy from the text files We can do this with two function i.e. Numpy is the name that came from ‘Numerical Python.’ It is a library in python which performs n-dimensional operations on arrays.

Load a csv file with NumPy, skip a row and select columnsIf we want to load/read jusa few columns of of the data file, we can use “usecols” option and specify the column indices that we want to load. By specifying different “skiprows”, we can skip multiple lines of a file. For example,If the data has header information in the first line of the file and if we want to ignore that we can use “skiprows” optionData = np.loadtxt(filename, delimiter=',', skiprows=1)By specifying “skiprows=1” while loading the numerical data, we skipping just the first line of the file. An open file object, or a string containing a filename.# load the data with NumPy function loadtxtData = np.loadtxt(filename, delimiter=',')Load a csv file with NumPy and skip a rowNumPy’s loadtxt function offers numerous options to load the data. The data produced by this method can be recovered using the function fromfile ().
