just wondering how to convert a set of code into comments, without having to go through each individual line of code and put a # at the beginning. Was thinking that maybe there was a quick way to highlight the code and then convert it into comment, atm i'm just cutting it off the code and then re-pasting it in later on.
Much appreciated :)
P.S. i m using Pycharm as my IDE
In jupyter notebook, we select lines of code and press ctrl and / key simultaneously to convert a set of code into comments. Also same for vice versa.
You can try it in Pycharm.
You can use the (""") symbol before and after the text you want to comment out. It is not exactly a comment and more of a text constant, but either way it is often used for documentation, so you can use it for multiline comments except for some cases when it causes unexpected errors
To avoid such cases you could simply use multiple single line comments by selecting the desired lines and using ctrl+/ to comment them out

I'm currently using Google Colab in order to take advantage of its free GPU. I was trying to modify a code that I copy and pasted from machinelearningmaster.com. However, whenever I try to add a new code line, for example "print("some words"), I get an indention error.
I have tried adding tabs or spaces before the print call but I still get the error. for example:
space,space,print("some words")
tab, tab ,print("some words")
I have also checked the colab editor settings, currently the indention width setting are set to two spaces.
The first three lines are part of the original code, the print statement is
my addition. I copy and pasted this directly from the colab editor. In Colab all four lines are aligned. As you can see here only the first three lines are aligned. I don't know what's going on.
img_path = images_dir + filename
ann_path = annotations_dir + image_id + '.xml'
count=count+1
print("this is count: ", count)
I expected this to print the value of count, instead I get an error message telling me:
IndentationError: unindent does not match any outer indentation level
Okay, after much searching and frustration, I have an idea of what went wrong, but even better, a solution to fix it.
It appears that the Google Collaborator (Colab) editor does not have a way to set it for tabs "\t" versus space (space-bar entries). From the settings tab on the cell you can set the width of the tab from 2 to 4, but these will be interpreted as 2 to 4 space-bar entries. Usually, this isn't a problem. However, if you're like me and you want to test out code from the web, or be lazy and just copy paste from your editor, problems can arise.
Here's how I fixed it. Before pasting the copied code into Colab, first put it into notepad++. Go to View> Show Symbols >Show All Characters, click on this, you should now be able so see all the characters in the code. Find a tab, it will look like an arrow pointing to the right -->, right click and copy it. Open Search> Find, open the Replace tab. Depending on your version of notepad++ the tab you copied will automatically be entered and the replace will already be set to four spaces. Hit "Replace all". This will automatically replace all tabs with equivalent spaces. Copy the code from notepad++ back to Colab. Now there will be no more conflicts.
I think using a simple find and replace tool will just work fine. I also came across this error recently in Colab and I went through #Rice Man solution. The only difference was I used Libre office writer instead of Notepad++. I also found this tool to be helpful. I am not proficient in using Colab but this solution worked for me.
Another quick fix that worked for me related to this question.
I was trying to run a python script in colab and faced this error though the line seems at an appropriate indentation in that script.
I checked with the !cat filename.py cmd, and found out that the actual indentation appears different than it is in the script (hence the error).
Taking that unindented line (according to the colab) at the start of the line and using space afterward fixed the error.
I used this website to fix the error.
Copy your code to the site, then click beautify button on top left. This will remove indention errors.
If you want to know where the indention error is coming from, use #Prachi answer.
I have the awesome vim-sexp and vim-sexp-mappings-for-regular-people plugins installed, and I've come across a situation I'm not sure how to solve.
Suppose I have the following form:
(alimony barbara (code determinant) eclair final-countdown)
How can I transform that to:
(alimony
barbara
(code determinant)
eclair
final-countdown)
I can go ahead and insert a newline before every inner-form/element, but that is a bit tedious. There should be a way with or without the sexp plugin
This is an old question, but maybe an updated answer will help someone who comes here in the future.
You don't have to write the program mentioned by Kaz. Others have already done it. I have not tried them, but here are a few:
fipp,
cljfmt,
cljstyle,
zprint,
joker. (The last one does more than code formatting.)
As Kaz suggests, once installed, you can pipe code to a formatter using !. You can even bind this operation to a key combination. Some of the formatters offer suggestions about how to do this sort of thing.
In addition, some vim IDE plugins, such as vim-iced provide support for using an external formatter.
A productive way to get this behavior would be, rather than fighting with Vim modules and extensions, to write a Lisp program which reads S-expressions and outputs them reformatted in the desired way. To use that program out of Vim, just pipe a range of lines into it using the ! command.
I noticed that when I place quotations around something in a comment line, the words in quotations change color to indicate that the interpreter sees them as a string. I found this confusing because I thought that the interpreter was supposed to ignore comments. I am curious to know if I did something wrong. The code is below.
# The output of the concatenation above would be:
# 'spameggs'
'spameggs' changes color even though it is part of a comment line.
Its showing me as comment ,No change of color of the text you are mentioning,which editor are you using .Seems like some editor problem.Try to open it in IDLE.IT will be all red color.
Thanks
It is a bug in Qpython3 for android. In Liclipse this worked fine, and remained as a comment.
i met interesting issue when im comparing two strings. Im reading data from file and everything works well. But then co-worker send me input file, which is just CTRL+C and CTRL+V of working file. And then miracle happend! VBA is so confused, that cant compare two simple strings and i fell of chair.
If you take a look at image you can see that comparison passed if condition where are two same strings, but it should not. Im a bit confused how this can happen.
So met someone something like this? Im realy start thinking about something like machine revolution from Terminator. (files are both saved in notepad++ and there are no strange characters or something like that)
Progress update
So i tried hints from guys in comments below. and ended with something like this
If CStr(Trim(rowArray(4))) <> (CStr("N/A")) Then
Contentent of rowArray(4) is still "N/A" string as on picture above and excel still thinks this strings arent same. I also saved file in pspad, netbeans, and normal notepad and issue is still same.
Use the immediate window to test the contents of the variable:
For i = 1 To Len(rowArray(4)): Print Asc(Mid(rowArray(4), i, 1)): Next
This will print the ASCII value of each character in the string - you can use this to determine what the extra character(s) are causing the issue.
as far as I know the only way to register aqlfunctions is via arangosh. JS functions very fastly get a few more lines of code which normally also have line breaks for better understanding. Whenever I paste them into the arangosh it gets corrupt as it excepts to get a "proper" end signal/sign. If I don't know it , the only way to reset it is a shotdown. My questions are:
Is there any shortcut like which resets the line input in such a case?
How can I write JS code into several lines and paste them into the arangosh directly?
Is there another way to register (more complex) JS functions I don't know?
Thanks for your help in advance.
<STRG> + D also works in windows.
Multiline doesn't work well with the CMD, it works partly with the cygwin shell window.
However, if the context shows that a function will start (using a brace) it will offer to add another line until the brace closes.
Probably the easiest way to get in more complex code is:
require("internal").load("c:\\tmp\\test.js")
which will be executed right away, so if you define functions in that, they will be usable in the shell context from then on.
