How do I make a exact duplicate copy of an array?

问题 How would I make an exact duplicate of an array? I am having hard time finding information about duplicating an array in Swift. I tried using .copy() var originalArray = [1, 2, 3, 4] var duplicateArray = originalArray.copy() 回答1: Arrays have full value semantics in Swift, so there's no need for anything fancy. var duplicateArray = originalArray is all you need. If the contents of your array are a reference type, then yes, this will only copy the pointers to your objects. To perform a deep

问题 I want to copy a file from a jar. The file that I am copying is going to be copied outside the working directory. I have done some tests and all methods I try end up with 0 byte files. EDIT : I want the copying of the file to be done via a program, not manually. 回答1: First of all I want to say that some answers posted before are entirely correct, but I want to give mine, since sometimes we can't use open source libraries under the GPL, or because we are too lazy to download the jar XD or what

How can I create a copy of an object in Python?

问题 I would like to create a copy of an object. I want the new object to possess all properties of the old object (values of the fields). But I want to have independent objects. So, if I change values of the fields of the new object, the old object should not be affected by that. 回答1: To get a fully independent copy of an object you can use the copy.deepcopy() function. For more details about shallow and deep copying please refer to the other answers to this question and the nice explanation in

Macro in Excel to Copy a Worksheet (by referencing every cell)

由 做~自己de王妃 提交于 2019-12-25 19:37:08
问题 I've found lots of examples for Copying Worksheets in VBA, or replacing formulas with values etc. What I want to do is copy an entire worksheet, but on the new worksheet, every cell refers back to its original. So in cell A1 of the new worksheet, it would simply have the formula "='Sheet1'!A1" Is there an easy way to do this? Thanks P.S. I need it to be a Macro, as I need to be able to run it on specific sheets, to copy all the cells from that sheet into a new one, not always from "Sheet1"

问题 I want to copy all files from one folder using tcl. This is the code that I have written so far, but it does not work. What is the problem? set files [glob -dir E:\Music *] puts "Moving files" foreach f { $files } { file copy $f E:\ } 回答1: My earlier assumption was wrong, and I unfortunately didn't notice that you were using braces around $files . Unlike languages like C, where parentheses or braces are part of syntactic constructions, braces are used for quoting in Tcl. In this case, $files
