The Joy of Learning: Tech and Computing Trivia!
1. What is the output of the following Python statement? print (6+15/5%3)
a. 13.5 b. 7 c. 6 d. 21.0
2. To open and read a text file named StudentRec.txt in folder D:ipython, which statement is the easiest way to read this file?
a. file = open('StudentRec.txt', 'r')
b. file = open('Studentinfo.txt')
c. file = open('D:llpythonllStudentRec.txt', 'r')
d. file = open('D:lpythonlStudentRec.txt', 'r')
3. What does the term CIA stand for in the course context?
a. Central Intelligence Agency
b. Confidentiality, Integration, Availability
c. Certified internal Availability
Answers:
1. The correct output of the Python statement is 7.
2. The easiest way to open and read the StudentRec.txt file in Python is by using the statement: file = open('StudentRec.txt', 'r').
3. In the course context, CIA stands for Confidentiality, Integration, and Availability.
The output of the Python statement print (6+15/5%3) will give 7, not 13.5, 6, or 21.0. In Python, the mathematical operations follow the BODMAS rule, i.e., Brackets, Orders, Division and Multiplication, Addition, and Subtraction. Hence, the division happens first, followed by the modulus operation, and then the result gets added to 6.
When it comes to reading a file in Python from the same folder, the easiest way to do this is by using the statement: file = open('StudentRec.txt', 'r'). This command opens the file in read mode and assumes it is located in the same folder as the Python application.
CIA in the course context stands for Confidentiality, Integration, and Availability. This acronym refers to the triad model of computer security, where Confidentiality ensures data is not accessed by unauthorized personnel, Integrity ensures data remains unaltered during transmission, and Availability ensures data is readily available when needed.
