jimi | A lib for C/C++

Basically, your if statement is:

if middle_name:

And you have set middle_name to:

middle_name = ''

So python thinks middle_name exists with value of '' This statement will hit only when middle_name not exists. But it exists with value of ''

To stop this, change your middle_name value to None keyword. And modify your if statement like this:

Flattening into tuples could help.

For example with:

You need to give image path properly check below

batch_iterator(words_tuple, 3) returns an iterator with ['jimi', 'bertrand', 'alain']. To get the list from it you can use next. You also need to switch the parameters when invoking batch_iterator() and change words_tuple to a list, or cast it in the assertion

A few suggestions about the way the dlgDisplayMessage Form handles the CommandLine arguments:

• You should use Environment.GetCommandLineArgs() to get an array of values passed to the command line. These values are meant to be separated by a space.
  The first item always represents the executable path. Recommended, it's a .Net method, much easier to translate to another .Net language.
  You could also use My.Application.CommandLineArgs, the difference is that the first item is the first parameter of the command line, not the executable path. Avoid Interaction.Command()

• I think that those lblMessageLine01 etc. parts are actually meant to be the content of some Labels. In this case, you should of course use the lblMessageLine01.Text property. You can use an interpolated string to add these values to the command line. Since these Labels may contain multiple words separated by a space, you need to enclose these values in double quotes. For example:

If lst is your list from the question:

Well, there's a method which does already what you need:

Local files can be easily tested. See Testing paths. For example, given the users

A few changes to the text rendering should get you close to what you're expecting.

• Use TextRenderer to draw the text
• Add TextFormatFlags.TextBoxControl and TextFormatFlags.NoPadding to the TextFormatFlags used in TextRenderer.DrawText() (see the Docs about these two)
• Override OnBorderStyleChanged() to replace the FixedSingle style with Fixed3D when the Control is custom-drawn. This is what the base class (TextBoxBase) does, otherwise you get the default internal border that shrinks the Win32 Control's Client area.
• Inflate the Control's ClientRectangle by -1 pixel when BorderStyle = BorderStyle.Fixed3D.

I added UpdateStyles() after the SetStyle() call: this forces the new Styles and also causes the Control to repaint itself.

Note that setting a Font that doesn't support all CodePoint (simplified: the Unicode chars in your Text) used when setting the Text of a control, may cause a Font Fallback.
In practice, the System will select a mapped surrogate Font that replaces the Control's Font. This happens transparently and without notice.
A different Graphic renderer can behave in a different manner in similar situations.

See the notes here:
How can a Label control display Japanese characters properly when the Font used doesn't support this language?

Somewhat different in a RichTextBox Control (the .Net base class is the same, but the Win32 Control is quite different):
Some Alt keys changes my RichTextBox font

Also, quite recently, all Asian Font rendering and UI presentation has been modified to better handle its characteristics. So the .Net version in use can also change the behavior.
The code here is tested with .Net Framework 4.8.
