These conditions can be used in several ways, most commonly in "if statements" and loops. An "if statement" is written by using the if keyword. In this example we use two variables, a and b, which are used as part of the if statement to test whether b is greater than a.

May 28, 2012 · I'm building a kind of question sequence as part of a program in Python 3.2. Basically, I ask a question and await an answer between two possibilities. If the given answer is not part of the two choices, I print a line and would like to re-ask the question until the correct input is given and then move on to the next question and repeat the ...

These conditional tasks can be achieved using the if statement. An if statement executes a block of code only when the specified condition is met. Syntax. # body of if statement. Here, condition is a boolean expression, such as number > 5, that evaluates to either True or False.
