math logarithms use the natural logarithm lotand it is more natural for me to type ln instead of log if you want to do thatjust do the followingln log summing series here is way to get an approximate sum of seriesin this case = - sum([ /( ** - for in range( , )] another examplesay you need the sine of each of the angles and here is quick way to do that[round(sin(radians( )), for in range( , , )[ third-party modules there are number of other third-party modules that you might find useful when working in the python shell for instancethere is numpy and scipywhich we mentioned in section there is also matplotliba versatile library for plotting thingsand there is sympywhich does symbolic computations
