braces

set B {pc_0::!mx_0 pi::$mx_0} puts $B set A "" foreach x $B { lappend A $x } puts $A The output of this program is pc_0::!mx_0 pi::$mx_0 pc_0::!mx_0 {pi::$mx_0} It is strange that tcl adds curly braces in second output. I guess it is because it uses $ symbol. But I really need to use it and I don't want the braces to be inserted. How this can be explained and how to avoid the braces? As a general rule, don't treat lists as strings . Pretend that they don't have a string representation. (The string representation is only useful for serialization, debugging, but not for the user). To convert

public void Finalise() ProcessFinalisation(true); Doesn't compile, but the correct version: public void Finalise() { ProcessFinalisation(true); } Compiles fine (of course). If I am allowed if's without brackets when the following code has only one line: if(true) CallMethod(); Why is the same not allowed for methods with one following line? Is there a technical reason? Since C# 6.0 you can declare: void WriteToConsole(string word) => Console.WriteLine(word) And then call it as usual: public static void Main() { var word = "Hello World!"; WriteToConsole(word); } The obvious answer is the

I need to produce an id surrounded by braces ( for example "{1234}" ). With the django template language, braces are also used to start a variable substitution, so I have some trouble in obtaining what I want. I tried {{{ id }}} {{ '{'id'}' }} {{ '{'+id+'}' }} { {{ id }} } None of these methods work, except the last one, which unfortunately produces "{ 1234 }", not what I want. I currently have two solutions : either I pass an id variable already containing the {} (ugly) or I write a custom filter and then write {{ id|add_braces }} (I prefer it). Before going this way, I prefer to ask if a

Just starting to figure Python out. I've read this question and its responses: Is it true that I can't use curly braces in Python? and I still can't fathom how curly braces work, especially since pages like Simple Programs: http://wiki.python.org/moin/SimplePrograms use curly braces all over the place. I understand square brackets and regular curved parentheses, but I don't know what's meant by "defining dictionaries" or what they're supposed to represent. Brenton Alker "Curly Braces" are used in Python to define a dictionary. A dictionary is a data structure that maps one value to another -

My input file is as below : HEADER {ABC|*|DEF {GHI 0 1 0} {{Points {}}}} {ABC|*|DEF {GHI 0 2 0} {{Points {}}}} {ABC|*|XYZ:abc:def {GHI 0 22 0} {{Points {{F1 1.1} {F2 1.2} {F3 1.3} {F4 1.4}}}}} {ABC|*|XYZ:ghi:jkl {JKL 0 372 0} {{Points {}}}} {ABC|*|XYZ:mno:pqr {GHI 0 34 0} {{Points {}}}} { ABC|*|XYZ:abc:pqr {GHI 0 68 0} {{Points {{F1 11.11} {F2 12.10} {F3 14.11} {F4 16.23}}}} } TRAILER I want to extract the file into an array as below : $array[0] = "{ABC|*|DEF {GHI 0 1 0} {{Points {}}}}" $array[1] = "{ABC|*|DEF {GHI 0 2 0} {{Points {}}}}" $array[2] = "{ABC|*|XYZ:abc:def {GHI 0 22 0} {{Points {

What is a list of every unicode bracket-like characters (including, for example: {}[]()<> )? What is a good way to search for unicode characters? There is a plain-text database of information about every Unicode character available from the Unicode Consortium; the format is described in Unicode Annex #44 . The primary information is contained in UnicodeData.txt . Open and close punctuation characters are denoted with Ps (punctuation start) and Pe (punctuation end) in the General_Category field (the third field, delimited by ; ). Look for those character, and you'll find what you're looking for

I'd just come across a very weird bit of php code: $oink{'pig'} = 1; var_dump($oink); $oink{'pig'} = '123123'; echo $oink{'pig'}; /* => 123123 */ echo $oink['pig']; /* => 123123 */ It works like an array, but nowhere mentioned in the manual. What is this? It is mentioned in the manual. {} is just an alternative syntax to [] § : Both square brackets and curly braces can be used interchangeably for accessing array elements (e.g. $array[42] and $array{42} will both do the same thing in the example above). The same goes the strings § : Characters within strings may be accessed and modified by
