Question

question 17
(1, 2, apple, 3) is a valid example of a tuple: true or false
true
false
question 18
for the code executed in python, write the answers that will be returned.
a) 5 % 2
b) 20.0 / 2
c) 7 // 2
d) 5.0 // 2
e) 19 + 1 == 21
f) bool(10)
g) int(\2000\)
h) float(cis 2000)
i) str(19)
j) bool(0)

Explanation:

Step1: Analyze each code snippet

• a) 5 % 2: The % operator in Python is the modulus operator. It returns the remainder of the division. $5\div2 = 2$ with a remainder of $1$. So, $5\%2 = 1$.
• b) 20.0 / 2: The / operator in Python performs floating - point division. $20.0\div2=10.0$.
• c) 7 // 2: The // operator in Python is the floor division operator. It returns the largest integer less than or equal to the quotient. $7\div2 = 3.5$, and the floor value is $3$.
• d) 5.0 // 2: For 5.0//2, since it is a floating - point floor division, $5.0\div2 = 2.5$, and the floor value is $2.0$.
• e) 19 + 1 == 21: First, calculate $19 + 1=20$. Then, check if $20 == 21$. The result is False.
• f) bool(10): In Python, any non - zero number (including positive and negative non - zero numbers) is considered True when converted to a boolean. So, bool(10) is True.
• g) int("2000"): The int() function can convert a string of digits (in base 10 by default) to an integer. So, int("2000") = 2000.
• h) float('CIS 2000'): The float() function expects a string that represents a number. A string like 'CIS 2000' which has non - numeric characters will raise a ValueError.
• i) str(19): The str() function converts an integer to a string. So, str(19)="19".
• j) bool(0): In Python, 0 is considered False when converted to a boolean.

Answer:

a) $1$
b) $10.0$
c) $3$
d) $2.0$
e) False
f) True
g) $2000$
h) ValueError
i) "19"
j) False
