在每一個小節的後面都會有筆記區以及問題區，尤其是問題區，請你好好思考。而在每一篇文章最後都會放上一些練習題，請嘗試完成他們!

    那為什麼印出type(x) 得到 <class 'str'> 呢?代表 x 是一個字串，這是因為 input 總是將你輸入進來的東西當成字串，但我想要讓 z = x + y 這個數學式子成立，所以需要用 int 來將字串轉換成整數再進行運算。

    沒錯，字串的相加，就是相連。那你要不要試試看相減?
    
+
    接下來我們來做個有趣的實驗，順便認識一下 f-string 
+
    1
+2
+3
+4
+5
+6
    a = 3.5
+b = int(a)
+print(f'The value of b is {b}, and its type is {type(b)}')
+c = float(b)
+print(f'The value of c is {c}, and its type is {type(c)}')
+print(b == c)
+
    
+
    那 f-string 是什麼東西呢?他是一種字串格式化(String Formatting)的方法，他會將括號內的東西轉換成字串，並將字串中的 {} 替換成括號內的東西。
    
+
    而執行完程式碼後，你會發現 b 與 c 的類別不同，但他們的值卻相同，這是因為 int() 與 float() 都是將括號內的東西轉換成整數與浮點數，而 int() 會將浮點數的小數點捨去，而 float() 則會將整數轉換成浮點數。
    
+
    那麼 b == c 是什麼意思呢?他是一個比較運算子(Comparison Operator)，他會比較等號左右兩邊的東西是否相等，如果相等，則回傳 True，否則回傳 False。
    
 
    那如果我今天想要一次輸入好幾個字串，每一個字串以空格來隔開呢?
 但在這之前，我們先來看一個小程式 : 
    
-
    1
-2
-3
    a, b = "Hello World".split()
-print(a)
-print(b)
+
    1
+2
+3
    a, b = "Hello World".split()
+print(a)
+print(b)
 
    
 
    我知道怪怪的，為什麼字串後面接了一個 .split() 呢?在這裡他很像是函式，但又不是函式，那他叫什麼呢?他被稱為 "Hello World" 這個字串的方法(Method)，但未來你可能還會聽到類別方法(Class Method)，以及靜態方法(Static Method) 等名詞，我怕你會搞混，所以你就先認逗點後面的是「方法」就好了。
    
 
    而 .split() 會把字串以括號內的東西來切割字串並回傳(那你想想括號內什麼都沒放，預設會是什麼?)，而看看等號左邊，我用 a, b 去接著，這稱為開箱(Unpacking)
    
 
    那現在你應該能看懂下面的程式碼了，因為 input() 也會回傳一個字串，因此他也能夠使用 .split()
