time input("enter the appointment time"print(interviewer"will interview"applicant"at"timethe statements are executed in the order they appear in the text of the programsequentially this is the simplest way for the execution of the program to flow you will see instructions later that alter that natural flow if we want to reload and modify the hello_you py program to put an exclamation point at the endyou could tryperson input('enter your name'print('hello'person'!'run it and you see that it is not spaced right there should be no space after the person' namebut the default behavior of the print function is to have each field printed separated by space there are several ways to fix this you should know one think about it before going on to the next section hint print with keyword parameter sep one way to put punctuation but no space after the person in hello_you py is to use the plus operatoranother approach is to change the default separator between fields in the print function this will introduce new syntax featurekeyword parameters the print function has keyword parameter named sep if you leave it out of call to printas we have so farit is set equal to space by default if you add final fieldsep=''in the print function in hello_you pyyou get the following example filehello_you py'''hello to you''illustrates sep with empty string in print person input('enter your name'print('hello 'person'!'sep=''try the program keyword parameters must be listed at the end of the parameter list they have the keyword namefollowed by an equal signbefore the value being given we will see another example shortly it is standard python convention that when giving keyword and valuethe equal sign has no space on either side (this is the only place you are not encouraged to set off an equal sign with spaces numbers and strings of digits consider the following problemprompt the user for two numbersand then print out sentence stating the sum for instance if the user entered and you would print 'the sum of and is you might imagine solution like the example file addition pyshown below there is problem can you figure it out before you try running ithint '''error in addition from input '' input("enter number" input("enter second number"print('the sum of 'xand 'yis ' + 'sep=''#error end up running it in any case we do not want string concatenationbut integer addition we need integer operands briefly mentioned in whirlwind introduction to types and functions (page was the fact that we can use type names as functions to convert types the operation on strings adds no extra space the input function produces values of string type beginning with python
