                    習題 7: 更多打印?

                    現在我們將做一批練習,在練習的過程中你需要鍵入代碼,并且讓它們運行起來。我不會解釋太多,因為這節的內容都是以前熟悉過的。這節練習的目的是鞏固你學到的東西。我們幾個練習后再見。不要跳過這些習題。不要復制粘貼!

                    你應該看到的結果?

                    $ python ex7.py
                    Mary had a little lamb.
                    Its fleece was white as snow.
                    And everywhere that Mary went.

                    加分習題?

                    接下來幾節的加分習題是一樣的。

                    1. 逆向閱讀,在每一行的上面加一行注解。
                    2. 倒著朗讀出來,找出自己的錯誤。
                    3. 從現在開始,把你的錯誤記錄下來,寫在一張紙上。
                    4. 在開始下一節習題時,閱讀一遍你記錄下來的錯誤,并且盡量避免在下個練習中再犯同樣的錯誤。
                    5. 記住,每個人都會犯錯誤。程序員和魔術師一樣,他們希望大家認為他們從不犯錯,不過這只是表象而已,他們每時每刻都在犯錯。
