optional arguments there are two optional arguments to the print function they are not overly important at this stage of the gameso you can safely skip over this sectionbut they are useful for making your output look nice sep python will insert space between each of the arguments of the print function there is an optional argument called sepshort for separatorthat you can use to change that space to something else for exampleusing sep=':would separate the arguments by colon and sep='##would separate the arguments by two pound signs one particularly useful possibility is to have nothing inside the quotesas in sep='this says to put no separation between the arguments here is an example where sep is useful for getting the output to look niceprint 'the value of + is ' + 'print 'the value of + is ' + 'sep''the value of + is the value of + is end the print function will automatically advance to the next line for instancethe following will print on two linesprint'on the first line 'print'on the second line 'on the first line on the second line there is an optional argument called end that you can use to keep the print function from advancing to the next line here is an exampleprint'on the first line 'end''print'on the second line 'on the first lineon the second line of coursethis could be accomplished better with single printbut we will see later that there are interesting uses for the end argument variables looking back at our first programwe see the use of variable called temp
