• Question 175:

  DRAG DROP

  Arrange the code boxes in the correct positions to form a conditional instruction which guarantees that a certain statement is executed when the speed variable is less than 50.0.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  One possible way to arrange the code boxes in the correct positions to form a conditional instruction which guarantees that a certain statement is executed when the speed variable is less than 50.0 is:

  if speed < 50.0:

  print("The speed is low.")

  This code uses the if keyword to create a conditional statement that checks the value of the variable speed. If the value is less than 50.0, then the code will print “The speed is low.” to the screen. The print function is used to display the output.

  The code is indented to show the block of code that belongs to the if condition.

  You can find more information about the if statement and the print function in Python in the following references:

• Question 176:

  You are designing a decision structure to convert a student's numeric grade to a letter grade. The program must assign a letter grade as speci ed as followed:

  

  For example, if the user enters a 90, the output should be Your letter grade is A. Likewise, if a user enters an 89, the output should be Your letter grade is B.

  

  Which of the following should you insert on Line-3, Line-5, Line-7 and Line-9?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

• Question 177:

  DRAG DROP

  Assuming that the phonc_dir dictionary contains namemumber pairs, arrange the code boxes to create a valid line of code which retrieves Martin Eden's phone number, and assigns it to the number variable.

  Select and Place:

  

  

  ---

  Explanation/Reference:

  number = phone_dir["Martin Eden"]

  This code uses the square brackets notation to access the value associated with the key “Martin Eden” in the phone_dir dictionary. The value is then assigned to the variable number. A dictionary is a data structure that stores key-value pairs,

  where each key is unique and can be used to retrieve its corresponding value. You can find more information about dictionaries in Python in the following references:
