Write python statement to create a one –dimensional array using arrange() function .Elements will be in the range 10 to 30 with a step of 4 (including both 10 and 30). Reshape this one-dimensional array to two dimensional array of shape(2,3). Then display only those elements of this two –dimensional array which are divisible by 5.

Use the numpy library to work with arrays in Python. Use variable = value to assign a value to a variable in order to record it in memory. Variables are created on demand whenever a value is assigned to them. Use print(something) to display the value of something. The expression array.shape provides the shape of an array (i.e. its dimensions.)

Using the command np.array, create the data array X_data and the target array X_target that correspond to the given data set. The data array should have 2 columns (one for the temperature, and one for the precipitations) and 20 lines. The components of the target array X_target should be either 0 (May 2018) or 1 (May 2019).
