![]() ![]() It isĮven more useful when it allows the programmer to express their mentalĬhunking, and how they’ve broken a complex problem into pieces. Statements in question are going to be used multiple times. This process is very useful whenever the program Of program statements is often refered to as “wrapping the code inĪ function”. wrapping code in a function The process of adding a function header and parameters to a sequence type conversion An explicit function call that takes a value of one type and computes aĬorresponding value of another type. truth table A concise table of Boolean values that can describe the semantics prompt A visual cue that tells the user that the system is ready to accept input data. ![]() Inside a branch of another conditional statement. nesting One program structure within another, such as a conditional statement logical operator One of the operators that combines Boolean expressions: and, In Python the keywords if, elif, and else are conditional statement A statement that controls the flow of execution depending on someĬondition. condition The Boolean expression in a conditional statement that determines whichīranch is executed. comparison operator One of the six operators that compares two values: =, !=, >, Python chained conditionals are written with if. chained conditional A conditional branch with more than two possible flows of execution. branch One of the possible paths of the flow of execution determined byĬonditional execution. Values result when a Boolean expression is evaluated by the Python Boolean value There are exactly two Boolean values: True and False. Boolean expression An expression that is either true or false. Boolean algebra Some rules for rearranging and reasoning about Boolean expressions. body The block of statements in a compound statement that follows the Glossary ¶ block A group of consecutive statements with the same indentation. Ok, so can we get tess to draw a bar chart? Let us start with some data to be charted,Ĭorresponding to each data measurement, we’ll draw a simple rectangle of that height, with a fixed width.ĥ.13. We use lor("blue","red") to set the turtle
