PyCharmCE中Ctrl-R快捷键及运行按钮失效（无输出窗口）求助

Hey John, let's work through this problem step by step—since your script runs perfectly in both PyCharm's built-in terminal and external terminals, the issue is almost certainly a UI or configuration glitch in PyCharm itself, not a problem with your code. Here are targeted fixes to try:

• Check if the Run output window is hidden/minimized
  It's easy to accidentally drag the Run window to the edge of the screen or minimize it, making it look like there's no output. Try pressing Alt+4 (PyCharm's default shortcut for the Run tool window) to bring it up, or navigate to View > Tool Windows > Run from the top menu. If you find it, right-click the window's title bar and make sure Pin Tab is checked to prevent it from hiding again.

• Reset your Run Configuration
  Corrupted run configurations can break the run functionality entirely. Click the dropdown menu next to the green run button, select Edit Configurations..., then find your script's configuration. Click the - button to delete it, then click + and add a new Python configuration, selecting your script file path. Save the new configuration and test running again.

• Invalidate PyCharm's cache
  Cached files often cause odd UI/functional bugs. Go to File > Invalidate Caches..., check the box for Invalidate and Restart, and let PyCharm reboot. This clears temporary files without affecting your code, and often resolves weird shortcut or run issues.

• Reverify your Keymap binding
  Even though you saw Ctrl+R in the Keymap, it's worth double-checking for conflicts or misbindings. Open File > Settings > Keymap, search for Run 'your_script_name', right-click it, and select Add Keyboard Shortcut. Rebind Ctrl+R (PyCharm will alert you if there's a conflict). You can also temporarily switch to the Default keymap from the dropdown menu, restart PyCharm, and see if the problem goes away.

• Disable "Run in Background" mode
  Sometimes PyCharm runs tasks in the background without showing the output window. If you can bring up the Run window, look for a small "Run in Background" icon (usually in the top-right corner of the window) and click it to toggle back to foreground execution. Also, in your Run configuration, make sure Run in terminal is not checked (though this is less likely since your terminal runs the script fine).

• Repair your PyCharm installation
  If none of the above works, corrupted installation files might be the culprit. Open Help > Find Action, search for Repair IDE, and run the repair tool. It will scan and fix any damaged files in your PyCharm installation.
