What is the proper way to format a multi-line dict in Python?

由 徘徊边缘 提交于 2019-11-27 06:03:24
In Python, I want to write a multi-line dict in my code. There are a couple of ways one could format it. Here are a few that I could think of: mydict = { "key1": 1, "key2": 2, "key3": 3, } mydict = { "key1": 1, "key2": 2, "key3": 3, } mydict = { "key1": 1, "key2": 2, "key3": 3, } I know that any of the above is syntactically correct, but I assume that there is one preferred indentation and line-break style for Python dicts. What is it? Note: This is not an issue of syntax. All of the above are (as far as I know) valid Python statements and are equivalent to each other. I use #3. Same for long

How do I fix the indentation of his huge html files which was all messed up? I tried the usual "gg=G" command , which is what I use to fix the indentation of code files. However, it didn't seem to work right on HTML files. It simply removed all the formatting. I also tried setting :filetype = xml , to see if tricking it into thinking this was an XML file would help but it still didn't do it. marcog With filetype indent on inside my .vimrc , Vim indents HTML files quite nicely. Simple example with a shiftwidth of 2: <html> <body> <p> text </p> </body> </html> There's several things that all

Example: If I have a document with 2 space indentation, and I want it to have 4 space indentation, how do I automatically convert it by using the Sublime Text editor? Here's a neat trick in Sublime Text 2 or 3 to convert your indentation spacing in a document. TL;DR: Converting from 2 spaces to 4 spaces: Ensure tab width is set to 2. Convert your 2-space indentation to tabs, switch to tab width 4, and then convert the indentation back to spaces. The detailed description: Go to: View -> Indentation It should read: Indent using spaces [x] Tab width: 2 Select: Convert Indentation to Tabs Then

The program pasted above gives me an error "Inconsistent use of tabs and spaces in indentation" at line "if temp == dna2:" specifically. Can someone please help me out in finding out how the indentation is incorrect? It means you have mixed up spaces

Xcode: Adjusting indentation of auto-generated braces?

由 浪子不回头ぞ 提交于 2019-11-27 05:12:36
问题 Code auto-generated by Xcode seems to have the opening brace on the same line by default: @interface Controller : NSObject { } I'd like the opening brace on a line of its own, like this: @interface Controller : NSObject { } This applies in general to any method / class auto-generated by Xcode. In Xcode preferences I have "Indent solo { by" set to 0: How can I fix this? 回答1: For Xcode 3.x, you can use the following: If you open up a terminal session and enter defaults write com.apple.Xcode

Copy-paste into Python interactive interpreter and indentation

由 懵懂的女人 提交于 2019-11-27 04:33:21
问题 This piece of code, test.py: if 1: print "foo" print "bar" can be succesfully executed with execfile("test.py") or python test.py , but when one tries to copy-paste it into python interpreter: File "<stdin>", line 3 print "bar" ^ SyntaxError: invalid syntax Why is it so? Can interpreter by configured in such a way that it would read copy-pasted text succesfully? I guess that may affect typing in the interpreter, but that's ok for me. 回答1: Indentation is probably lost or broken. Have a look at

Indenting #defines

由 泄露秘密 提交于 2019-11-27 03:22:14
I know that #define s, etc. are normally never indented. Why? I'm working in some code at the moment which has a horrible mixture of #define s, #ifdef s, #else s, #endif s, etc. All these often mixed in with normal C code. The non-indenting of the #define s makes them hard to read. And the mixture of indented code with non-indented #define s is a nightmare. What is the benefit of not indenting #define s? Does it make me a bad person if I indent them? Isn't this much nicer? #ifdef SDCC #if DEBUGGING == 1 #if defined (pic18f2480) #define FLASH_MEMORY_END 0x3DC0 #elif defined (pic18f2580) #define

How to write an empty indentation block in Python?

问题 The runtime keeps telling me: expected an indented block But I don't want write nothing inside my except block, I just want it to catch and swallow the exception. 回答1: Just write pass as in try: # Do something illegal. ... except: # Pretend nothing happened. pass EDIT: @swillden brings up a good point, viz., this is a terrible idea in general. You should, at the least, say except TypeError, DivideByZeroError: or whatever kinds of errors you want to handle. Otherwise you can mask bigger
