5 1 Shell Python Shell 運算子整數與浮點數值表示式語法錯誤把值儲存到變數中

Python 好好玩 - 趣學電玩遊戲程式設計 IDLE IDLE Python Shell Python Shell Shell >>> 2 + 2 Enter Return

6 Python 好好玩 - 趣學電玩遊戲程式設計 IDLE IDLE Python Shell Python Shell Shell >>> Enter Return 1-1 Shell Shell Python 1-1 運算子 + - * / 運算加法減法乘法除法 - * / Python

7 第 1 章互動式 Shell Integers Ints Floating-point numbers floats Python values Shell expressions 1-2 運算子值值表示式 1-2 Shell Enter >>> >>> 8*6 48 >>> >>> Python Shell >>>

8 Python 好好玩 - 趣學電玩遊戲程式設計 Python * * 3 (1 + 2 ) * (3 + 4) 21 (1 + 2) (3 + 4) * 3 / Shell Shell

9 第 1 章互動式 Shell >>> 8 * 3 / / 24 / Shell 5 + Enter >>> 5 + SyntaxError: invalid syntax 前與後 SyntaxError Python Shell >>> 變數指定陳述句 assignment statement = Shell >>> spam = 15 >>> spam

10 Python 好好玩 - 趣學電玩遊戲程式設計 Enter Python >>> expressions 陳述句 statements Shell spam = 15 Enter spam = spam = spam 東西 stuff spam eggs bacon Python Shell Enter >>> spam = 15 >>> spam 15 spam spam 15 Shell

11 第 1 章互動式 Shell >>> spam = 15 >>> spam spam spam spam + 5 Python NameError >>> spam = 15 >>> spma Traceback (most recent call last): File "<pyshell#1>", line 1, in <module> spma NameError: name 'spma' is not defined spam spma Shell >>> spam = 15 >>> spam >>> spam = 3 >>> spam spam spam 15 spam = spam 3 spam

15 2 Python Hello World! 字串字串的連接資料型別 ( 如字串或整數型別 ) 使用 File Editor 來編寫程式

16 Python 好好玩 - 趣學電玩遊戲程式設計在 IDLE 中儲存和執行程式執行的流程注釋 print() 函式 input() 函式區分大小寫 Python 字串 strings ' Shell >>> spam = 'hello' Python Shell spam spam Python 'hello' >>> spam = 'hello' >>> spam 'hello' 'hello' 'Hi there!' 'KITTENS' '7 apples, 14 oranges, 3 lemons' 'Anything not pertaining to elephants is irrelephant.' 'A long time ago, in a galaxy far, far away...' 'O*&#wY%*&OCfsdYO*&gfC% YO*& % 3yc8r2'

17 第 2 章編寫程式 + 字串連接 string concatenation Shell 'Hello' + 'World!' >>> 'Hello' + 'World!' 'HelloWorld!' 'HelloWorld!' >>> 'Hello ' + 'World!' 'Hello World!' + 資料型別 data type 'Hello' 5 Python + IDLE Shell IDLE File Editor Shell File New File
