I'm trying to convert someone's Ruby code into my Python code. The originally developer is no longer with us and I don't know Ruby. Most of his code is easy enough to follow, but some of the following syntax is tripping me up. Example: myTable = '' myTable << [ 0, 1, 0, 0, 0, 300].pack('vvvvvv') ...

What is the difference in these two statements in python? var = foo.bar and var = [foo.bar] I think it is making var into a list containing foo.bar but I am unsure. Also if this is the behavior and foo.bar is already a list what do you get in each case? For example: if foo.bar = [1, 2] would I get this? var = foo.bar #[1, 2] a...
I was playing around with list comprehensions to get a better understanding of them and I ran into some unexpected output that I am not able to explain. I haven't found this question asked before, but if it /is/ a repeat question, I apologize. I was essentially trying to write a generator which generated generators. A simple generator t...
Hi, I'm currently integrating a payment system into my website. I have a response script which basically takes in the data from the secure server and displays to the customer if the payment has gone through or not. My problem is that the if statement is actually displaying both messages to the customer, even if the payment has been suc...
I've been an avid learner of the Python language for quite some time. Having more than 6 years of Java[professional] experience, coupled with a bit of C++ [hobby] experience - it's fair to say my perspective is deeply entrenched in the idioms brought forth by such statically typed, strongly bound languages. In short - i could say the old...
I have visited Vim website , script section and found several synthax checkers for python. But which one to choose ? I would prefer something that supports python 3 as well, even though I code in python 2.6 currently. Do all these checkers need a module like pychecker and pyflakes ? I could install the most popular from scripts datab...
Hello everyone, I would like to loop thru a given directory and seach in all pre-filtered files for a search word. I prepared this code, but it is not looping thru all files, only the last file which was found is analyzed. Ideally all files should be analyzed and the output should be saved in a textfile. Could someone help? Thank you in...
In a book I found following (translation): Initialization means assigning the value of the variable at the declaration time. int X=5 is called an initialization command. EDIT: It just says that term initialization is used only when you assign value at the declaration time. If you do it later, its just assignement (according to it -...
I wrote this simple program today, but I found that cin.get() refuses to work unless there are 2 of them. Any ideas? #include <iostream> using namespace std; int main(){ int base; while ((base < 2) || (base > 36)){ cout << "Base (2-36):" << endl; cin >> base; } string base_str = "0123456789abc...
Hello, I am investigating how a syntactic evolution of language affects its semantics. For instance, java's for loop syntax evolved in its version 5 to a compact one. Do the designers have to prove that even with this syntax the semantics are still preserved! May be this is a trivial example. So, in general, how can one prove that a lan...
Hi All, I am just curious to know why this is allowed. int i=0;; I accidentaly typed that. But the program compiled. I noticed it after many days that I have typed ;; After that I tried with different symbols like ~, !, : etc etc Why is that not allowed where as first one is allowed. Just curious to know. ...
Hi, I know using goto is something most people say to avoid, however I have read on various places that sometimes it is useful if you need simple code. Currently I have very simple program that needs to be repeated if user selects so: static void Main() { Restart: ... string UserChoice=Console.ReadLine(); if (UserChoice...

While coding in C#, I by mistake added a strudel sign before a variable in if statement (instead of exclamation mark). bool b = false; if (@b) { } I surprised it compiled successfully without any error. I wonder: What is the meaning of the above code? ...
