練習問題2回答

while True:
    try:
        time = int(input("何時ですか？(0〜24): "))
    except:
        continue
    if 0 <= time <= 24:
        break

if  5 <= time <= 10:
    print("おはよう")
elif 11 <= time <= 18:
    print("こんにちわ")
else:
    print("こんばんわ")

解説

  1. while文と if文でbreakを使って で0から24以外の数字を入力された際に繰り返す処理を行う
  2. try exceptのエラー処理で数字以外が入力された場合の処理を入れる
  3. inputされた数値は、そのあとのif文で数値比較するためにintに変換する
  4. inputされ、数値変換した情報を time(変数名はなんでも良い）に代入する
  5. if文を条件に合わせて記載する
