You have probablry used computers to do all sorts of useful and interesting things. In each application, the computer. PyCharm is the best IDE Ive ever used. With PyCharm, you can access the command line, connect to a database, create a virtual environment, and manage your version. Builtin Functions The Python interpreter has a number of functions built into it that are always available. They are listed here in alphabetical order. Why Python Linux Journal. My first look at Python was an accident. I didnt much like what I saw at the time. It was early 1. 99. Mark Lutzs book Programming Python from. OReilly Associates had recently come out. OReilly books. occasionally land on my doorstep, selected from among the new. Ive given up trying to understand. One of them was Programming Python. I. found this somewhat interesting, as I collect computer languages. Download Aplikasi Penangkap Wifi Untuk Laptop. I. know over two dozen general purpose languages, write compilers and. My most. recently completed project, as I write this, is a special purpose. SNG for manipulating PNG Portable Network. Graphics images. Interested readers can surf to the SNG home page. I have also written implementations of several odd general purpose. Retrocomputing Museum page. I had already heard just enough about Python to know that it. So. I dived into Programming Python with one. Perl does. not Perl, of course, is the 8. It has largely replaced shell as the scripting language. UNIX library and system calls, and partly to. Perl modules built by a very active Perl. The language is commonly estimated to be the CGI. Net. Larry. Wall, its creator, is rightly considered one of the most important. Open Source community, and often ranks third behind. Linus Torvalds and Richard Stallman in the current pantheon of. At that time, I had used Perl for a number of small projects. Id found it quite powerful, even if the syntax and some other. It seemed to me that Python would have quite. I read, I. looked first for what seemed to set it apart from Perl. I immediately tripped over the first odd feature of Python. The language has no. C and Perl brace syntax instead, changes in. And, like most hackers on. I recoiled in reflexive disgust. I am just barely old enough to have programmed in batch. FORTRAN for a few months back in the 1. Most hackers arent. Indeed, the term free format, used back then to. Pascal and C. has almost been forgotten all languages have. Or almost all, anyway. Its. hard to blame anyone, on seeing this Python feature, for initially. Thats certainly how I felt. I skimmed through the rest of. I didnt see much. Python, except maybe that the syntax seemed. Perls and the facilities for doing basic GUI. I put the book back on the shelf, making a mental note that I. GUI centered project in Python. I really understood the language. But I. didnt believe what Id seen would ever compete effectively with. Perl. A lot of other things conspired to keep that note way down on. The rest of 1. 99. I wrote and published the. The Cathedral and the Bazaar. But I did. find time to write several Perl programs, including two of. One of them. keeper, is the assistant still. Metalab software archive. It generates the web pages you see at. Linux INDEX. html. The other, anthologize, was used. Post. Script for the sixth edition of. Linux from the Linux Documentation Projects archive of HOWTOs. Both programs are available at Metalab. Writing these programs left me progressively less satisfied. Perl. Larger project size seemed to magnify some of Perls. The syntax that had. More than one. way to do it lent flavor and expressiveness at a small scale, but. And many of the features that were later patched. Perl to address the complexity control needs of bigger. These problems combined to make large volumes of Perl code. Also, I found I was spending more and more. And, most damning of all, the resulting code. Ugly programs are like ugly suspension. A language that makes it hard to write elegant code. With a baseline of two dozen languages under my belt, I could. By mid 1. 99. 7, I was. One course I did not consider was going back to C as a.

GUI. interface replete with selection buttons, slider bars and fill out. The thought of implementing this in Perl did not thrill me. I. had seen GUI code in Perl, and it was a spiky mixture of Perl and. Tcl that looked even uglier than my own pure Perl code. It was at. this point I remembered the bit I had set more than six months. This could be an opportunity to get some hands on. Python. Of course, this brought me face to face once again with. Pythons pons asinorum, the significance of. This time, however, I charged ahead and roughed out. GUI elements. Oddly enough. Pythons use of whitespace stopped feeling unnatural after about. I just indented code, pretty much as I would have. C program anyway, and it worked. That was my first surprise. My second came a couple of hours. I noticed allowing for pauses needed to. Programming Python I. I could type. When I realized this, I was quite startled. An. important measure of effort in coding is the frequency with which. An important measure of good language design. When youre writing working code nearly as fast as you can. But that didnt make sense. I was regularly pausing to look up. This was my first clue that, in Python, I was actually. Most languages have so. Python was the first general purpose language. Id ever used that reversed this process. Not that it took me very long to learn the feature set. I. wrote a working, usable fetchmailconf, with GUI, in six working. Python itself. This reflects another useful property of. C is a famously compact language. Perl is notoriously. Theres more than one way to do. Perl is the possibility of compactness. But my most dramatic moment of discovery lay ahead. My design. had a problem I could easily generate configuration files from the. GUI actions, but editing them was a much harder problem. Or. rather, reading them into an editable form was a problem. The parser for fetchmails configuration file syntax is. Its actually written in YACC and Lex, two. UNIX tools for generating language parsing code in C. In. order for fetchmailconf to be able to edit existing configuration. I thought it would have to replicate that elaborate parser. Python. I was very reluctant to do this, partly because of the. I wasnt sure how to. The last thing I needed was the extra labor of keeping the. Download Driver Momodesign Md-@ Plus. This problem stumped me for a while. Then I had an. inspiration Id let fetchmailconf use fetchmails own parser I. Python initializer. For the file above, the result. Listing 2 to save space, some data not. Listing 2. Python could then evaluate the fetchmail. This wasnt quite the last step in the dance. What I really. wanted wasnt just for fetchmailconf to have the existing. There would be three kinds of objects in this tree. Configuration the top level. Site representing one of the. User. representing user data attached to a site. The example file.
