              Python數字運算【每日一個知識點第133期-Python】

              NumberPython的一種基本數據類型,用于存儲數值。作為編程語言的基礎之一,其重要性毋庸置疑,我們之前也曾經帶大家了解過關于number的一些知識。從今天開始,我們將帶領大家深入了解數字運算。


              Python 解釋器可以作為一個簡單的計算器,您可以在解釋器里輸入一個表達式,它將輸出表達式的值。

              表達式的語法很直白: +, -, * 和 / 和其它語言(如Pascal或C)里一樣。例如:

              >>> 2 + 2
              4
              >>> 50 - 5*6
              20
              >>> (50 - 5*6) / 4
              5.0
              >>> 8 / 5  # 總是返回一個浮點數
              1.6

              注意:在不同的機器上浮點運算的結果可能會不一樣。

              在整數除法中,除法(/)總是返回一個浮點數,如果只想得到整數的結果,丟棄可能的分數部分,可以使用運算符?//?:

              >>> 17 / 3  # 整數除法返回浮點型
              5.666666666666667
              >>>
              >>> 17 // 3  # 整數除法返回向下取整后的結果
              5
              >>> 17 % 3  # %操作符返回除法的余數
              2
              >>> 5 * 3 + 2 
              17

              等號(=)用于給變量賦值。賦值之后,除了下一個提示符,解釋器不會顯示任何結果。

              >>> width = 20
              >>> height = 5*9
              >>> width * height
              900

              Python 可以使用?**?操作來進行冪運算:

              >>> 5 ** 2  # 5 的平方
              25
              >>> 2 ** 7  # 2的7次方
              128

              變量在使用前必須先”定義”(即賦予變量一個值),否則會出現錯誤:

              >>> n   # 嘗試訪問一個未定義的變量
              Traceback (most recent call last):
                File "<stdin>", line 1, in <module>
              NameError: name 'n' is not defined

              不同類型的數混合運算時會將整數轉換為浮點數:

              >>> 3 * 3.75 / 1.5
              7.5
              >>> 7.0 / 2
              3.5

              在交互模式中,最后被輸出的表達式結果被賦值給變量?_?。例如:

              >>> tax = 12.5 / 100
              >>> price = 100.50
              >>> price * tax
              12.5625
              >>> price + _
              113.0625
              >>> round(_, 2)
              113.06

              此處,?_?變量應被用戶視為只讀變量。
