如何通过 wxPython 在 messageBox 中使用 python 换行？

Question

"\n" doesn't work for me here, going to say that before anyone suggests it.

I am currently working on a dialog message, which works fine. It shows an OK button with an information icon. In the dialog, (or messageBox), I am outputting an array of strings, but the issue is that these string don't start on a newline so the dialog looks a little messy. Here's an example:

myArray = ["Bananas", "Apples", "Pears", "Mangos"]

def showMessagebox():
   gui.messageBox(myArray, "Juicy fruits", wx.ICON_INFORMATION)

the output then does:

Bananas Apples Pears Mangos

Even when I put a "\n" before them, I also tried putting an "\n" after them. it won't work: It is actually including the "n" within the string! Not what I want. What I actually want is:

Bananas
Apples
Pears
Mangos

Doing something like "\n bananas" or "bananas \n" doesn't work. I assume that's because it's a messageBox. I want to know what will work! Help is greatly appreciated thank you =)

For demonstration, here's a screenshot of the dialog

You are passing in a list instead of a string. Try

gui.messageBox('\n'.join(myArray), "Juicy fruits", wx.ICON_INFORMATION)

instead.
