高级编程技术第六周平时作业

10-11 喜欢的数字：

First program:

import json

filename = 'number.json'

number = input("Input your favorite integer number: ")
try:
    number = int(number)
except ValueError:
    print(number + ' is not a valuable integer number.')
else:
    with open(filename, 'w') as f_obj:
        json.dump(number, f_obj)
    print('OK')

Second Program:

import json

filename = 'number.json'

try:
    with open(filename) as f_obj:
        number = json.load(f_obj)
except FileNotFoundError:
    print('You should tell me your favorite number first.')
else:
    print("I know your favorite number! It's " + str(number))

11-1 城市和国家：

import unittest

def city_country(city, country):
    return city.title() + ', ' + country.title()

class CityCountryTestCase(unittest.TestCase):

    def test_city_country(self):
        c_c = city_country('santiago', 'chile')
        self.assertEqual(c_c, 'Santiago, Chile')

unittest.main()

11-2 人口数量：

import unittest

def city_country(city, country, population):
    return city.title() + ', ' + country.title() + ' - population ' + str(population)

class CityCountryTestCase(unittest.TestCase):

    def test_city_country(self):
        c_c = city_country('santiago', 'chile', 20000000)
        self.assertEqual(c_c, 'Santiago, Chile - population 20000000')

unittest.main()

import unittest

def city_country(city, country, population=50000000):
    return city.title() + ', ' + country.title() + ' - population ' + str(population)

class CityCountryTestCase(unittest.TestCase):

    def test_city_country(self):
        c_c = city_country('santiago', 'chile', 20000000)
        self.assertEqual(c_c, 'Santiago, Chile - population 20000000')

    def test_city_country_population(self):
        c_c = city_country('santiago', 'chile')
        self.assertEqual(c_c, 'Santiago, Chile - population 50000000')

11-3 雇员：

import unittest

class Employee():

    def __init__(self, F_n, S_n, Y_s):
        self.First_name = F_n
        self.Second_name = S_n
        self.Yearly_salary = Y_s

    def geive_raise(self, num=5000):
        self.Yearly_salary += num

class EmployeeTestCase(unittest.TestCase):

    def setUp(self):
        self.employee = Employee('Kiko', 'Green', 20000)

    def test_give_default_raise(self):
        self.assertEqual('Kiko Green', self.employee.First_name + ' '
            + self.employee.Second_name) 
        self.assertEqual(self.employee.Yearly_salary, 20000)

    def test_give_custom_raise(self):
        self.employee.geive_raise()
        self.assertEqual(self.employee.Yearly_salary, 25000)
        self.employee.geive_raise(2000)
        self.assertEqual(self.employee.Yearly_salary, 27000)
