argument to the print function is the calculation python will do the calculation and print out the numerical result this program may seem too short and simple to be of much usebut there are many websites that have little utilities that do similar conversionsand their code is not much more complicated than the code here second program entershere is program that computes the average of two numbers that the user num eval(input'enter the first number')num eval(input'enter the second number')print'the average of the numbers you entered is '(num +num )/ for this program we need to get two numbers from the user there are ways to do that in one linebut for now we'll keep things simple we get the numbers one at time and give each number its own name the only other thing to note is the parentheses in the average calculation this is because of the order of operations all multiplications and divisions are performed before any additions and subtractionsso we have to use parentheses to get python to do the addition first typing things in case case matters to pythonprintprintand print are all different things for nowstick with lowercase as most python statements are in lowercase spaces spaces matter at the beginning of linesbut not elsewhere for examplethe code below will not work temp eval(input'enter temperature in celsius')print'in fahrenheitthat is ' / *temp+ python uses indentation of lines for things we'll learn about soon on the other handspaces in most other places don' matter for instancethe following lines have the same effectprint'hello world'print 'hello world'print'hello worldbasicallycomputers will only do what you tell themand they often take things very literally python itself totally relies on things like the placement of commas and parentheses so it knows what' what it is not very good at figuring out what you meanso you have to be precise it will be very frustrating at firsttrying to get all of the parentheses and commas in the right placesbut after while it will become more natural stilleven after you've programmed for long timeyou will still miss something fortunatelythe python interpreter is pretty good about helping you find your mistakes
