Module 3 Graded Quiz: Python Programming Fundamentals :Python for Data Science, AI & Development (Applied Data Science Specialization) Answers 2025

Question 1 — Output of code

x = "Gone"
if x == "Go":
print("Go")
else:
print("Stop")
print("Mike")

  • ❌ Go Stop

  • ✅ Stop Mike

  • ❌ Go Mike

  • ❌ Mike

Question 2 — Purpose of comparison operators

  • ❌ To convert numeric variables to string representations

  • ✅ To evaluate expressions and assign the resulting Boolean values to variables

  • ❌ To initialize variables with default values

  • ❌ To perform mathematical operations

Question 3 — What ends a while loop?

  • ✅ The evaluation of its conditional expression to False

  • ❌ Presence of a print statement

  • ❌ Number of statements in the loop

  • ❌ Executes exactly five times

Question 4 — Output of class code

Correct output:

x= A y= B

  • ❌ y=B

  • ❌ x=A

  • ❌ x=y=

  • ✅ x=A y=B

Question 5 — Output of enumerate loop

for i, x in enumerate(['A','B','C']):
print(i, 2*x)

  • ✅ 0 AA 1 BB 2 CC

  • ❌ 0 A 1 B 2 C

  • ❌ 0 A 2 B 4 C

  • ❌ 1 AA 2 BB 3 CC

Question 6 — Result of object mutation

p2 = Points('Boston','Chicago')
p2.y='Denver'

  • ❌ x= Denver y= Boston

  • ❌ x= Boston y= Chicago

  • ✅ x= Boston y= Denver

  • ❌ x= Denver y= Denver

Question 7 — Range validation

32 is between 20 and 40.

  • ❌ “Invalid”

  • ✅ “Valid”

  • ❌ False

  • ❌ None

Question 8 — Output of do()

a = 1
def do(x):
a = 100
return x + a
print(do(1))

Returns 1 + 100 = 101.

  • ❌ Product of local variable and parameter

  • ❌ Sum of global variable and parameter

  • ✅ Sum of local variable and parameter

  • ❌ Value of global variable only

Question 9 — Efficient function to add two numbers

  • ❌ Built-in sum with tuple conversion

  • ❌ Built-in sum with individual parameters

  • ✅ Direct return of parameter summation

  • ❌ Intermediate variable assignment

Question 10 — Why multiple except statements?

  • ❌ Ensure catching the error for program termination

  • ✅ To determine the type of error thrown and its location within the program

  • ❌ Skip specific sections of code

  • ❌ Not necessary
