Conditions

    Programs need to be able to do different things based on their input. Here are a few examples:

ª      If Zai’s answer is correct, add one point to his score.

ª      If he got hit, close the program.

Programs check (do a test) to see if a certain condition is true or not. In the first example above, the condition is “got the right answer.” Python has only a few ways to test something, and there are only two possible answers for each test: true or false. Look at this example.

 

Notice that in the ‘if statement’, there are two equal signs. “=” means assigning, while “==” means checking. Also, don’t forget to put colon after the statement or else it will now work. Aside from if and else, you can also use elif. It means else + if. It is usually used in conditions under conditions.
