问题 I am making a Tkinter GUI to do nothing except call images - and of course, I have struggled to find decent tkinter documentation all along. There is a line of my code which cannot seem to do as asked - I want to call up all the values in a dictionary and individually print and pull an image by the same name for each one before the next value is called up.

问题 I have a python program with a wxpython GUI and some command line parameters. I generate a single windows executable with py2exe. I don't want to have a command line window in the background, so py2exe is making this a pythonw executable without this window. This is equivalent to use the *.pyw extension. The problem is, if you want to see the available command line arguments, you naturally do "main.exe -h" on a shell. Even though argparse is providing this information, it doesn't reach stdout

问题 I have a script that converts Google Earth .kml / .kmz files to shapefiles with a simple GUI interface written in Tkinter. My problem is that it works fine with a .py extension, but when saved out with a .pyw extension it stalls while reading my .kml files. There are no error messages and it doesn't crash. The GUI launches OK, etc, but it just stops and always at about the same place. I'm using Python 2.5, and had the same results with Python 2.7. Any ideas what could cause this? 回答1: .pyw
