• Question 27:

  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)
  C. math.floor(x)
  E. math.fabs(x)

  ---

  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

• Question 28:

  You are writing an application that uses the sqrt function. The program must reference the function using the name squareRoot.

  You need to import the function.

  Which code segment should you use?

• Question 29:

  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 must be removed.

  Which code should you use?

  A. open("local_data", "r")
  B. open("local_data", "r+")
  C. open("local_data", "w+")
  D. open("local_data", "w")
  C. open("local_data", "w+")

  ---

  Modes 'r+', 'w+' and 'a+' open the file for updating (reading and writing). Mode 'w+' truncates the file.
