Chapter 3: Conditionals

Question 1

The sequence of statements within a compound statement.

Answer 1

body

Question 2

An expression whose value is either True or False.

Answer 2

boolean expression

Question 3

One of the alternative sequences of statements in a conditional statement.

Answer 3

branch

Question 4

A conditional statement with a series of alternative branches (more than two)

Answer 4

chained conditional

Question 5

One of the operators that compares its operands: ==, !=, >, <, >=, and <=.
Nonzero numbers are TRUE

Answer 5

comparison operator /
relational operator

Question 6

A statement that controls the flow of execution depending on some condition.

Answer 6

conditional statement

Question 7

The boolean expression in a statement that determines which branch is executed.

Answer 7

condition

Question 8

A statement that consists of a header and a body. The header ends with a colon (:). The body is indented relative to the header.

Answer 8

compound statement

Question 9

Where we construct a logical expression with additional comparisons to take advantage of the short-circuit behavior and avoid errors

Answer 9

guardian pattern

Question 10

One of the operators that combines boolean expressions: and, or, and not.

Answer 10

logical operator

Question 11

A conditional statement that appears in one of the branches of another conditional statement.

Answer 11

nested conditional

Question 12

A list of the functions that are executing, printed when an exception occurs.

Answer 12

traceback

Question 13

When Python is part-way through evaluating a logical expression and stops the evaluation because Python knows the final value for the expression without needing to evaluate the rest of the expression.

Answer 13

short circuit

Question 14

Boolean order of priority

Answer 14

or
and
not

Question 15

OR operator

Answer 15

Short-circuit operator, so it only evaluates the second argument if the first one is FALSE.

Question 16

AND operator

Answer 16

Short-circuit operator, so it only evaluates the second argument if
the first one is TRUE

Question 17

NOT operator

Answer 17

Has a lower priority than non-Boolean operators, so not a == b is interpreted as not (a == b), and a == not b is a syntax error.

Question 18

ZeroDivisionError

Answer 18

error when you try to divide by zero

Question 19

pass

Answer 19

used in a function where you have a header but no body

Question 20

interactive mode print format

Answer 20

need a space between block statement and print statement

Question 21

alternative execution

Answer 21

IF-THEN-ELSE logic

Question 22

try/except

Answer 22

try:
desired code
except:
jumps here is desired code causes and error
eg. “Enter valid input”
