[Tutor] What has Editor X got that PyWin32 hasn't?
Hello. I haven't much experience with programming. I'd like to point this question to programmers who write in editors other than the default PyWin32: Why do you use your editor rather than using Pywin? What feature has editor X got that PyWin hasn't? (That is, other than My editor runs on unix / linux; while that does count for something it is rather irrelevant to my current situation.) Thanks in advance, Omer. ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] Simple way to compare Two lists
Thank you Kent, Michael, Tom and anyone else I'm forgetting who took time to reply. I don't work quite so fast, very limited personal computer time means I only do it on weekends, I read through your suggestions and eventually found a way to speed-up the proccess through sorting the Two lists, then manually iterating through each of them. This way I've completely canceled the need to compare Two lists: instead just ensuring I start from a point not taken in One list and having to only check whether Item not in BigList. [If anyone's interested, I should have the script finished and thoroughly tested on, ah, next weekend, and I could post a link here.] Again, Thx. -Omer.

If SmallList and BigList are sorted (in order), there is a faster method: def IsAPartOfList(SmallList,BigList): for i in BigList: for j in SmallList: if i==j: return true if ij: break return false (I'm not sure how encouraged using break statements are, so wait for a tutor to answer) break is fine! If the list you are searching is sorted you can use the bisect module to do a binary search instead of the linear search above. If one list is already sorted but the other isn't, it may still be faster to sort the unsorted list then use the method above. I don't think BigList has to be sorted in the above algorithm. If both lists are sorted I suppose you could write it like a merge sort, walking along both lists looking for a match. Kent - Park yourself in front of a world of choices in alternative vehicles.

[Tutor] Simple way to compare Two lists
Hello! I desperately need a simple way to compare whether any item of SmallList is in BigList. My current way, def IsAPartOfList(SmallList,BigList) for item in SmallList: if item in BigList: return True return False Takes up waay too much time to process. Can anyone think of any better way? Usually, SmallList is generated using range(Long, Long+ ~300) BigList is usually of a few hundreds of long numbers. The long numbers themselves represent date in seconds-since-the-epoch time. (E.G: time.time() is now in seconds-since-the-epoch, 1186739653.467 at the time of writing.) Thank you for your help, Omer Tabach.

Re: [Tutor] Money Matters
Hello! I read this list because I'm new to Python and I really am learning an average of something new I did not know from every digest hitting my inbox. I have no interest on the matter of money.

Re: [Tutor] The whole Roman to Dec and vice versa issue
Hey, I'm a rather new programmer, but it seems to me the digital to roman should be coded: While Digital_Input 0: If Digital_Input 1000 then: Roman = + M, Digital_Input = - 1000 elif Digital_Input 900 then: Roman = + C, Digital_Input = - 900 ... Now if someone could please clarify [or forward me to clarifications of-] separation of data from logics I should be very grateful. [Come to that, if someone could point me to a *simple* gui which I can use in python, keep in mind I did learn a little VB, I should be grateful as well.] Thank you. Omer Tabach. Quoting Bob Gailer : Digital to Roman pseudocode: 1. if digital_input is greater than 1000: subtract 1000 from it and add M to string roman_result # How do you do that, add one character to the end of an existing string? Start with an empty string: roman_result = To add a character at the end: roman_result += M # Python shorthand for roman_result = roman_result + M roman_result + M would also work, right/ I'm just trying to save time on typing in the code, right # also, how do I modify the digital_input variable (it's an integer) digital_input -= 1000 is that somewhat like digital_result = digital result - int(1000)? several times through the conversion process? You will be processing the input in a loop (while or for). running = True and while running is how I've tended to set (my pseudocode) As you gain familiarity with Python you will develop ways to separate data from logic. I might say more about this later, but right now I'm about to drive north a bit. I have already gained some familiary with separating data manipulation (data and logic, as a whole) from the code for the user interface, that's something that oen of my advisors has been big on. - Now that's room service!
