Let's take a look at a more complex nested loop where the inner loop iterations depends on the outer loop variable. for x in range(5): for y in range(x+1): print('*', end='') print() To understand how this nested loop works, let's first look at the outer (x) loop. It's aforloop over range(5), which that means the value ofxwill be0, 1, 2, 3, 4at each outer loop iteration. Now let's look at the inner loop: it iterates overrange(x+1). So when the outer loop variablexis0, the inner loop goes over range(x+1)=range(0+1)=range(1), which runs just 1 iteration, printing out 1 star. When the outer loop variablexis1, the inner loop goes over range(1+1)=range(2), which runs 2 iterations, printing out 2 stars. And so on and so forth. In the end, how many stars in total does this nested loop print out? answer:

15

Using functions as objects can be useful in a number of applications. For example, let's say we have four functions: draw_circle, draw_triangle, draw_square, draw_dot. We want to define a draw function such that when a user passes in an shape number, namely 1, 2, 3, or 4, it calls one of the above four functions respectively. Normally you would have to write an if-elif sequence like below. if shape==1: draw_circlel) elif shape==2: draw_triangle() elif shape==3 draw_square() elif shape==4: draw_dot () But using function objects we can dramatically simplify the code to just 1 line. Which of the following is equivalent to the above if-elif sequence? a. [draw_circle, draw_triangle, draw_square, draw_dot] [shape] b. [draw_circle, draw_triangle, draw_square, draw_dot] [shape]() c.

What's the list generated by the following list comprehension? [i**2 for i in range(1, 5)] f. 12, 4, 6, 81 a. 10, 1, 4, 9, 16] b. 12, 4, 6, 8, 101 c. 10, 1, 4, 9, 16, 251 d. 11, 4, 9, 16, 251 e. [1, 4, 9, 161 v

e. [1, 4, 9, 16]

What's the output of the following code? Please read the code carefully. def double (c): C *= 2 print([double(c) for c in '123']) a. ['246'] b. I'2', '4', '6'] с. ['123123'] d. [', '2', '3'1 e. [None, None, None] f. ['11', '22', '33'1

Which of the following is a valid name for a variable in Python? a. 1_counter b. Friendly's c. my-excavator d. while e. false

e. false

Which expressions below is a correct implementation of the condition "neither x nor y is larger than 20" (i.e. the expression returns True if neither x nor y is larger than 20, and False otherwise)? Select all that are correct. Incorrect choices will result in partial deductions. a. not (x>20 and y>20) b. x>20 or y>20 c. x>20 and y>20 d. x<=20 or y<=20 e. not (x>20 or y>20) f. x<=20 and y<=20

e. not (x>20 or y>20)

Identify the error with the code written below. The program is supposed to ask the user for two numbers, then output the subtraction of the two numbers. num1 = input("Input the first number") num2 = input("Input the second number") print(num1 - num2) a. print() can only print out strings, not numbers. b. The input() function cannot take parameters inside its parentheses c. The data types of the two variables num1 and num2 must be declared first d. If one number is an integer and the other is a float, you cannot subtract them e. num1 and num2 are both strings, subtracting two strings is invalid.

e. num1 and num2 are both strings, subtracting two strings is invalid.

Which of the following tasks can only be implemented using a while loop and can NOT be implemented using a for loop? a. iterate over every character in a string b. check whether a given integer is a prime number or not c. print out all elements in a list d. sum up all integers from 1 to 100 e. repeatedly print out random numbers until the user enters the string 'quit'

e. repeatedly print out random numbers until the user enters the string 'quit'

Which of the choices is a correct line of code that can replace XXX in the program below, resulting in valid, error-free code? def calc_sum(a, b):return a + b XXXprint(y) a. y = calc_sum(9) b. y = calc_sum(4 + 5) c. y = calc_sum('a', 10) d. y = calc_sum() e. y = calc_sum(4 + 5, 5 + 6) f. calc_sum(y, 4, 5)

e. y = calc_sum(4 + 5, 5 +6)

What would the following code print out if grade = 85 (please read the code carefully)? if grade >= 90: print('A') elif grade >= 80: print('B') if grade >= 70: print('C') else: print('D') print('--') a. C -- b. A -- c. B -- d. A B C -- e. A B -- f. B C -- g. A C --

f. B C --

Given a positive and odd integer n, which of the following generates the sequence 1, 3, 5, 7 ... n? (1 and n are both included in the sequence) a.range(1, n+2) b.range(1, n) c.range(1, n, 2) d.range(1, n+1) e.range(1, n-1, 2) f.range(1, n+1, 2)

f. range (1, n+1, 2)
