• C. print("Congratulations on" + int(end - start) + "years of service!")
• D. print("Congratulations on" + str(end - start)) + "years of service!")

Answer:

B

Explanation:
int must be converted to string

Question 4

You develop a Python application for your school.
You need to read and write data to a text file. If the file does not exist, it must be created. If the file has content, the content

Question 10

You are creating a function that manipulates a number. The function has the following requirements:
A float is passed into the function

The function must take the absolute value of the float

Any decimal points after the integer must be removed

Which two math functions should you use? Each correct answer is part of the solution. (Choose two.)

• A. math.fmod(x)
• B. math.frexp(x)
• C. math.floor(x)
• D. math.ceil(x)
• E. math.fabs(x)

Answer:

C E

Explanation:
C: math.floor(x) returns the largest integer less than or equal to x. E: math.fabs(x) returns the absolute value of x.
Incorrect Answers:
A: math.fmod() takes two variables
B: math.frexp(x) returns the mantissa and exponent of x as the pair (m, e). m is a float and e is an integer D: math.ceil(x)
returns the smallest integer greater than or equal to x
