Ans: 0.5. 71% got it right! In PY2 '/' means integer division returning the floor of the division. In PY3 by default we get true division with '/', but we can still compute floor division by using '//'. PEP 238. #ManQuantPy3Quiz #Python #Python3 #py3 #PythonQuiz #programming

PY3 does not allow comparing None to integers, thus we get a TypeError Exception #ManQuantPy3Quiz #Python #Python3 #py3 #PythonQuiz #tech #programming

Answer to Q8/10 of #ManQuantPy3Quiz: The output under PY3 is '49, 50, 51'. When iterating bytes sequences, each element is treated as a byte and it's ASCII value is printed: byte '1' -> 49 byte '2' -> 50 byte '3' -> 51 #Python #Python3 #py3 #PythonQuiz #tech #programming

Answer to Q2: In PY3, it finishes almost instantly (<1 sec). 'range' behaves as 'xrange' does in PY2, benefitting from lazy evaluation. Thus, we can access a[77] without having to compute the entire a[]. #ManQuantPy3Quiz #Python #Python3 #py3 #PythonQuiz #programming

On PY3, instead of always rounding up for x.5 as in PY2, Bankers Rounding is used: round towards the direction of the nearest even integer. round(2.5) gives 2 & round(3.5) gives 4. Helpful with averages! Only 17% got that one! #ManQuantPy3Quiz #Python #Python3 #py3 #PythonQuiz
Question 4/10 of #ManQuantPy3Quiz: what's the output of the following on Python 3? $ python2 > round(2.5) 3.0 #Python #Python3 #py3 #PythonQuiz #tech #programming
Answer to Q7 of #ManQuantPy3Quiz: The instruction 'print(01)' raises a SyntaxError Exception under PY3. Previously, '01' meant octals, but the new syntax makes it '0o1'. #Python #Python3 #py3 #PythonQuiz #tech #programming

Answer to Q9/10 of #ManQuantPy3Quiz : On PY2, there is not really a bytes type, it's just an alias for the str type. Under PY3, the parameter to this bytes constructor indicates the amount of bytes to allocate! Boom! 🎇 #Python #Python3 #py3 #PythonQuiz #tech #programming

Answer to Q3/10 of #ManQuantPy3Quiz: Attempting to use 'i' under PY3 raises a NameError Exception. In PY3, list comprehensions have their own scope so that variable names are not leaked to outer scopes. #Python #Python3 #py3 #PythonQuiz #tech #programming

Answer to Q10 of #ManQuantPy3Quiz: The Person class has a __eq__ method but no __hash__ method. In PY2, it would inherit object's __hash__, but under PY3, __hash__ is assigned to None, making the object unhashable. Boom! #Python #Python3 #py3 #PythonQuiz #tech #programming
