both operands are true.
A Boolean expression using the and operator returns True when one operand is true. both operands are equal. both operands are true. neither operand is true.
running a set of statements a predictable number of times. counting through a sequence of numbers.
A for loop is convenient for making choices in a program. describing conditional iteration. running a set of statements a predictable number of times. counting through a sequence of numbers.
entry-controlled loop.
By default, the while loop is an infinite loop exit-controlled loop. entry-controlled loop. continuation loop
The loop is infinite.
Consider the following code segment:count = 1while count <= 10:print(count, end = " ")Which of the following describes the error in this code? The loop is infinite. The loop is off by 1. The loop control variable is not properly initialized. The comparison points the wrong way.
5 4 3 2
Consider the following code segment:count = 5while count > 1:print(count, end = " ")count -= 1What is the output produced by this code? 2 3 4 5 5 4 3 2 5 4 3 2 1 1 2 3 4 5
At least one
