AssertEquals Vs. AssertEqual In Python

Answer : Good question! Actually, in Python 2.6, both assertEqual and assertEquals are convenience aliases to failUnlessEqual . The source declares them thus: # Synonyms for assertion methods assertEqual = assertEquals = failUnlessEqual In Python 3, to your point, failUnlessEqual is explicitly deprecated. assertEquals carries this comment :-) # Synonyms for assertion methods # The plurals are undocumented. Keep them that way to discourage use. # Do not add more. Do not remove. # Going through a deprecation cycle on these would annoy many people. So, the upshot appears to be that you should use whatever you like for Python 2.x, but tend toward assertEqual for Python 3. A 3.3 update: From 26.3.7.1.1. Deprecated aliases : For historical reasons, some of the TestCase methods had one or more aliases that are now deprecated. The following table lists the correct names along with their deprecated aliases: Method Name | Deprecated alias | ...

C#: Looping Through Lines Of Multiline String

Answer : I suggest using a combination of StringReader and my LineReader class, which is part of MiscUtil but also available in this StackOverflow answer - you can easily copy just that class into your own utility project. You'd use it like this: string text = @"First line second line third line"; foreach (string line in new LineReader(() => new StringReader(text))) { Console.WriteLine(line); } Looping over all the lines in a body of string data (whether that's a file or whatever) is so common that it shouldn't require the calling code to be testing for null etc :) Having said that, if you do want to do a manual loop, this is the form that I typically prefer over Fredrik's: using (StringReader reader = new StringReader(input)) { string line; while ((line = reader.ReadLine()) != null) { // Do something with the line } } This way you only have to test for nullity once, and you don't have to think about a do/while...

Collapse All #regions Only(!) In C# (Visual Studio)

Answer : in Visual Studio 2017 I have to activate 'Collapse #regions when collapsing to definitions' in Tools -> Options -> Text Editor -> C# -> Advanced explicitly to collapse all when pressing Ctrl + M + O Ctrl + M + O will collapse all. Ctrl + M + L will expand all. (in VS 2013 - Toggle All outlining) Ctrl + M + P will expand all and disable outlining. Ctrl + M + M will collapse/expand the current section. These options are also in the context menu under Outlining. Right click in editor -> Outlining to find all options. (After disabling outlining, use same steps to enable outlinging.) The Visual Studio extension Productivity Power Tools 2015 from Microsoft has a feature called Quick Launch Tasks that adds new commands to the Quick Launch menu. One of them is CollapseRegions and it does exactly that. The opposite command is ExpandRegions and it expands all regions for quick browsing of the entire file. These commands can be used pre...

Automatically Replace Dots With Commas In A Google Sheets Column With Google Script

Answer : Select the column you want to change. Goto Edit>Find and Replace In Find area put "." in Replace with area put "," The error occurs because .replace is a string method and can't be applied to numbers. A simple workaround would be to ensure the argument is always a string, there is a .toString() method for that. in your code try return [row[0].toString().replace(".", ",")];
