The while statement allows you to repeat a block of statements in your program. -
✔✔True
The while statement is called a loop, because the control of your program jumps back
up to a point earlier in the program than the end of the repeat block. - ✔✔True
You can name a variable while in your program without Python confusing your variable's
name and the while keyword. - ✔✔False
The condition in the while statement's syntax must be a bool expression. - ✔✔True
If the condition in a while statement evaluates to False, control jumps over the repeat
block and onto the next statement at the same level of indentation as the while
keyword. - ✔✔True
If the condition in a while statement evaluates to True, control jumps into the repeat
block and evaluates the first statement of the repeat block. - ✔✔True
After the final statement of the repeat block is evaluated, control jumps back up to the
condition of the while statement and evaluates it again. - ✔✔True
You can write any statements you'd like inside of the repeat block, such as other print
statements, variable declaration and assignment statements, conditional if-else

c. Forward progress must be made toward the while loop condition becoming False -
✔✔a, c
Your computer knows when you write an infinite loop in your program and will not run

.An iteration of a loop is one evaluation of the repeat block and it should be making
incremental progress toward the goal of the loop. - ✔✔True
The number of iterations a loop runs for is the number of times the repeat block is
evaluated. - ✔✔True
The then block of an if statement and the repeat block of a while statement are
semantically the same, including what happens after each block completes. -
✔✔False
The phrase "if loop" is incorrect and should not be said. The phrase "while loop" is
correct. - ✔✔True
You can use a while loop to iterate through each item in a collection. For example, a str
