This Is A Boolean Variable That Signals When Some Condition Exists In The Program:

The if statement is used to create a(n) ________ _________, which allows a program to have more than one path of execution. The if statement causes one or more statements to execute only when a Boolean expression is true.

The if statement is used to create a decision structure, which allows a program to have more than one ___________________. The if statement causes one or more statements to execute only when a Boolean expression is true.

The if statement is used to create a decision structure, which allows a program to have more than one path of execution. The if statement causes one or more statements to execute only when a Boolean expression is _____.

The if statement is used to create a decision structure, which allows a program to have more than one path of execution. The if statement causes one or more statements to execute only when a(n) ________ expression is true.

A(n) ________ _________ is a logical design that controls the order in which a set of statements execute.

A control structure is a logical design that controls the order in which a set of statements execute.

In a(n) _________ __________’s simplest form, a specific action is performed only if a certain condition exists. If the condition does not exist, the action is not performed.

The if clause begins with the word if, followed by a condition, which is an expression that will be evaluated as either true or false. A(n) ______ appears after the condition. Beginning at the next line is a block of statements. All of the statements in a block must be consistently indented. This indentation is required because the Python interpreter uses it to tell where the block begins and ends.

When the if statement executes, the _________ is tested. If the _________ is true, the statements that appear in the block following the if clause are executed. If the _________ is false, the statements in the block are skipped.

When the ___ __________ executes, the condition is tested. If the condition is true, the statements that appear in the block following the if clause are executed. If the condition is false, the statements in the block are skipped.

When the if statement executes, the condition is tested. If the condition is true, the statements that appear in the ______ following the if clause are executed. If the condition is false, the statements in the ______ are skipped.

The if statement tests an expression to determine whether it is true or false. The expressions that are tested by the if statement are called Boolean expressions, named in honor of the English mathematician _______ ______.

In the 1800s _______ ______ invented a system of mathematics in which the abstract concepts of true and false can be used in computations.

Typically, the Boolean expression that is tested by an if statement is formed with a(n) __________ ________. A(n) __________ ________ determines whether a specific relationship exists between two values.
