>>>x = 13 ? 2
objective is to make sure x has a integer
value, select all that apply (python 3.xx)
  • (A) x = 13 // 2
  • (B) x = int(13 / 2)
  • (C) x = 13 % 2
  • (D) all of the mentioned
💬 Discuss
✅ Correct Answer: (D) all of the mentioned

Explanation: // is integer operation in python

a = a*2
return a
>>>example("hello")
  • (A) indentation error
  • (B) cannot perform mathematical operation on strings
  • (C) hello2
  • (D) hello2hello2
💬 Discuss

📊 Problem Solving and Python Programming
Q. What is the average value of the
following Python code snippet?
>>>grade1 = 80
>>>grade2 = 90
>>>average = (grade1 + grade2) / 2
  • (A) 85.0
  • (B) 85.1
  • (C) 95.0
  • (D) 95.1

📊 Problem Solving and Python Programming
Q. What is the output of print 0.1 + 0.2 == 0.3?
  • (A) true
  • (B) false
  • (C) machine dependent
  • (D) error
💬 Discuss
✅ Correct Answer: (B) false

Explanation: neither of 0.1, 0.2 and 0.3 can be represented accurately in binary. the round off errors from 0.1 and 0.2 accumulate and hence there is a difference of 5.5511e-17 between (0.1 + 0.2) and 0.3.
