Question 2

In Python, there is a handy module, called shelve, that is built on top of pickle, and implements a serialization dictionary where objects are pickled and associated with a key. Therefore, you can open your shelved data file and access your pickled objects via the keys the way you do when you access Python dictionaries. For example:import shelve my_shelve = shelve.open('my_shelve.shlv', flag='c')The flag parameter in the shelve.open() function specifies the mode in which the shelve database should be opened. The default values of the optional flag parameter is set to 'c'. This parameter can accept values like 'r', 'w', 'c' or 'n'. Select the answer that correctly describes these values.

A : 'r' - open existing database for reading and writing'w' - open existing database for reading only'c' - open database for reading and writing, creating it if it doesnâ€™t exist'n' - always create a new, empty database, open for reading and writing

B : 'r' - open existing database for reading only'w' - open existing database for reading and writing'c' - open database only for writing, creating it if it doesnâ€™t exist'n' - always create a new, empty database, open only for reading

C : 'r' - open existing database for reading only'w' - open existing database for reading and writing'c' - open database for reading and writing, creating it if it doesnâ€™t exist'n' - always create a new, empty database, open for reading and writing

D : 'r' - open existing database for reading only'w' - open existing database for reading and writing'c' - always create a new, empty database, open for reading and writing'n' - open database for reading and writing, creating it if it doesnâ€™t exist

Answer: C

Question 3

The Zen of Python says "Beautiful is better than ugly."With that in mind, which code best fits that sentence?

A : from urllib.request import urlopenwith urlopen('http://python.org') as response: html = response.read().decode('utf-8') lines = [line.strip() for line in html.splitlines() if line][:5]for line in lines: print(line)

B : from pathlib import Pathimport zipfile path = Path.cwd().joinpath('cars.csv') with zipfile.ZipFile('archive.zip', 'w') as zip: zip.write(path, path.name, compress_type=zipfile.ZIP_DEFLATED)

C : from functools import partialdef fv(rate, m, n, pv): return pv * (1 + (rate / m)) ** (n * m)annual_acc_factor = partial(fv, n=1, pv=1)print(annual_acc_factor(0.04, 1))print(annual_acc_factor(0.04, 4))print(annual_acc_factor(0.06, 12))

D : from pathlib import Pathimport zipfilepath = Path.cwd().joinpath('cars.csv') with zipfile.ZipFile('archive.zip', 'w') as zip: zip.write(path, path.name, compress_type=zipfile.ZIP_DEFLATED)

Answer: B
