"xxx.has_key(a)" vs "a in xxx"
by Łukasz Ligowski Oct. 30, 2008

Oct. 30, 2008

Hi, There is small inconsistency (or I don't understand it right) between python 2.5 docs and python 2.6 docs. 2.5 docs say that: "a.has_key(k) Equivalent to k in a, use that form in new code" 2.6 docs say that: "dict.has_key(key) is equivalent to key in d, but deprecated." which is true? L

Is ctypes appropriate in my case?
by dudeja.rajat＠gmail.com Oct. 30, 2008

Oct. 30, 2008

Hi, I've a dll and its header file that controls an hardware. I want to write a wrapper for this dll in Python. What is the best way that I can write a wrapper? I know ctypes modules and have used it before. As far as I know ctypes is only used to call the dll functions in a python module. This is not appropriate for writing a wrapper. Please suggest some way to write a wrapper. Thanks and regards, Rajat

Re: Tkinter: How to get Label wraplength functionality in Text Box
by Mudcat Oct. 30, 2008

Oct. 30, 2008

Awesome...there it goes. I guess my main problem was trying to evaluate the box before it had been displayed (or all the frame propagations were finished). The key was getting the <Map> binding in there once I got the count functionality to work. After all that...such a simple function: def textBoxResize(self, event): widget = event.widget dispLines = widget.count("1.0", "end", "displaylines") widget.config(height=dispLines) Thanks for the help!

Is psyco available for python 2.6?
by sert Oct. 30, 2008

Oct. 30, 2008

I used the windows installer for the latest version of psyco, which is labeled as compatible with 2.5, but it gives the following error: ImportError: DLL load failed: The specified module could not be found. (check that the compiled extension 'C:\Python26\lib\site- packages\psyco\_psyco.pyd' is for the correct Python version; this is Python 2.6)

一個年薪200萬的竹科高階主管與大家分享的心得
by 9705may＠gmail.com Oct. 30, 2008

Oct. 30, 2008

一個年薪200萬的竹科高階主管與大家分享的心得當我的女朋友告訴我，要走出來學習成長、找備胎時，我心想我的工作這麼好了，還要出來學什麼，找什麼備胎。我的女友，看到了我看不到的危機，便告訴我”你的工作非常的好，但是拿掉你的專業，你剩什麼？“ 她講了一個故事：有一隻海螺，常看到漁夫拿著長長的釣竿要釣他，每當他看到這危機時，他的頭就縮進去他認為十分安全的殼內，躲避一切。隔了幾天，他想伸出頭來看看風景，呼吸一下空氣。他突然發現… 周遭環境變的都不太一樣了，他身處在一家海產店，外面標價：50元。我就像這個，遇到困難，都躲起來。我們在老闆眼中，也只是一個價錢。我的女友又說：在順境時找出路比在逆境時找退路還來的簡單。在我上班的公司，若有一個人要升遷，要三位主管聯合視訊開會，其中一位主管得報告為何要讓他升遷，有2/3 的人通過，那個被提名的人才可以升遷。上個月，我有位部屬因為工作表現不佳，副總一句話，他就走路。升遷要很多人同意，可是離職卻只是一個人講，就得走。我們的未來就掌握在一個人的二片薄薄的嘴唇上。但是透過女友的一句話，我讓我的未來掌握在自已手中。她說: 如果你認為你是個人才，那你要放在對的舞台，不然老闆會把你當木材燒。不改變自己的心態去嘗試•不願跨出勇敢的第一步就永遠是坐領死薪水、只會羨慕有錢人的上班族美國NO.1財務顧問／暢銷書作者Robert Allen已經準備好利用他的「革命性Internet行銷系統」來協助您同時擁有健康和長長久久的持續性收入終極致富網站http://msi-team.com/wine119/ MSI在家工作網http://whymsi.com/wine119/
