Question

we can write in a messsage box using

    msg = "Hello World"
    dlg = wx.MessageDialog(self, msg, "About", wx.OK)
    dlg.showmodal()
    dlg.Destroy()

now the problem is writing a list using msg = list…
where list is our output that we want to display in the msg box.

i am geting an error that “string or unicode type required”

Answer 1

The message in a message box must be a string. Thus a list must be converted to a string. There is more than one way of doing this, but my recommendation is to do this.

mylist = ['blah', 7, 'etc...']
#make sure the values are strings
mylist = [str(x) for x in mylist]
msg = ', '.join(mylist)

dlg = wx.MessageDialog(self, msg, "About", wx.OK)
dlg.showmodal()
dlg.Destroy()

If you don’t want a comma replace it with something else. You could even to this if you want the output to be one line per item in list.

msg = '\n'.join(mylist)

I think that’s what your after.
