演習問題①の解答

# 全ての果物の金額を変数に代入する
apple = 100
orange = 120

# 「税抜き価格は〇〇円になります」と出力する
non_taxed_price = apple * 2 + orange
print('税抜き価格は' + str(non_taxed_price) + '円になります')

# 「税込価格は〇〇円になります」と出力する
tax_included_price = int(non_taxed_price * 1.1)
print('税込み価格は' + str(tax_included_price) + '円になります')

演習問題②の解答

test_scores =[50, 65, 45, 75, 70]

# 解答1) 国語の点数(50点→80点)に書き換えてください
test_scores[0] = 80

# 解答2) 体育の点数(90点)を加えて出力してください
test_scores.append(90)
print(test_scores)

# 解答3) 「最低スコアは◯点、最高スコアは◯点です。」と出力してください
print("最低スコアは" + str(test_scores[2]) + "点、最高スコアは" + str(test_scores[-1]) + "点です。")

演習問題③の解答

test_scores_d ={'国語':50,'算数':65,'理科':45,'社会':75,'英語':70}

# 解答1) 国語の点数(50点→80点)に書き換えてください
test_scores_d['国語'] = 80

# 解答2) 体育の点数(90点)を加えて出力してください
test_scores_d['体育'] = 90
print(test_scores_d)

# 解答3) 「最低スコアは◯点、最高スコアは◯点です。」と出力してください
print("最低スコアは" + str(test_scores_d['理科']) + "点、最高スコアは" + str(test_scores_d['体育']) + "点です。")
