I had this same problem and I got an answer here.

It's is because the line you read is always followed by a \n character. You need to remove it. Hence, just replace that last part of your code with this. .strip() will do for you. str(current_location).strip("\n")

Whenever you read a line from a text file, it adds a \n character to tell that new line started from there. You need to remove that while printing or it will mess up with your current statement

Looking at the three instances of apiString and rewriting them to use the more succinct F-strings, they all appear to be of the form:

Use a matrix to store your results instead of individual vectors.

A neater way is to also use a 2nd loop (this relies on you also using sw.Lambda1, sw.Lambda2, ... instead of sw1.Lambda, sw2.Lambda, ..., which is a better option). You could use 8 individual lines to assign the rows of the matrix if you wanted though.

What I wanted to achieve:

Support English but use German as the default language that is also used if the user's language settings don't include English or German.

How I achieved this in Xcode 12.5:

1. Add "German (de)" to the "Localizations" list via the little "+" button. In the new Choose files and reference language to create German localization pop-up every storyboard file should already be ticked by default. This adds .strings (German) localization files for all storyboards in the Project Navigator on the left:

1. In Main.storyboard's File Inspector tick the "English" box in the "Localization" section (this might take a while). This adds an additional Main.strings (English) file in the Project Navigator. Repeat this step for each storyboard, including the launch screen.

1. To change the "Development Language", which is the language the app uses by default and also if it doesn't support any of the languages the user set in their device's language settings, close Xcode, then open the project's .xcodeproj file with a text editor (I used BBEdit, which is free). There should be a list of files, including project.pbxproj. Open it and set developmentRegion (= development language) to the language code of the language that you added in step 1, so in my case "de". Do not use a different code (e.g. add "German (de)" but set it to "de_CH") because that's going to create an additional localization.

1. There are now two ways to finish this part of localization:

• A. Leave it as is. Changes in storyboard aren't going to affect any of the .strings files. Advantage: The text can be edited directly (without using storyboard), which is useful if you aren't the person who's working on the translations. Disadvantage: You can't quickly see and test the changes to a translation in storyboard but have to run the app in the simulator or on an actual device.

• B. Use the default language as "Base" language: Untick "German" for every storyboard and hit "Remove" in the pop-up, which removes the localizations in the list. This way changes to the storyboard affect the default language, which makes it easier to test changes.

I used version B:

Important:

These .strings files are only used for storyboards! If you also want to set localized text at runtime using NSLocalizedString (e.g. for an error dialog), then you have to add an additional Localizable.strings file (more details here):

1. File - New - File - Strings File - Call it Localizable.strings
2. Click "Localize" in its File Inspector and pick one of the languages you want to use in code.
3. Afterwards, also in the File Inspector, you can tick the other languages in the "Localization" section (including the development one).

Bonus infos:

You can change the app language of the simulator through the scheme:

Product - Scheme - Edit Scheme - Run (left side) - Options tab (right side) - App Language

You can also show a preview of the currently selected UIViewController and change its displayed language without starting a simulator:

Editor - Preview - In the new preview window on the right there's a button in the bottom right

Disclaimer: I found this solution by testing different things, as there's currently no tutorial for this (using the latest Xcode version). If this is not the "right" way to do localization, please post your own answer and I'll check it out.

row.update({columnField : false});

This is not evaluating the variable the way you think it should. Actually you are setting a property named "columnField" instead of using the value of the columnField variable.

You need to use Computed Property Names. Wrap your variable in [brackets] like this:

row.update({ [columnField] : false});

You can spread the switches to a separate bit values like that:

First join the dict.keys by | which is the or operator in regular expression. Then use Series.str.extract to extract these values from your column. Finally use Series.map to map the values with your dict:
