Im using python 3 and already have all the data required from previous tasks

Write in two external files called 'Deg_grid.txt' and 'Etot grid.txt' the data calculated in previous tasks, E and angle, respectively. For the format of the file, use the same xy grid format available from the files in Taks 1 -InDeg-grid.txt., provide the angles in degrees. Add a meaningful header to the file. The file should be human readable, meaning that the data should be written with a defined formatting: Use floating point format for the angles with two decimal places (e.g., 12.12), and scientific notation format for the electric field E, with five decimal places (e.g. 1.12345e+01)
