Can't run py files by using hot key in sublimetext3 - python-3.x

Question

I have update my sublime3 to newest version, then I can't use hotkey to run my py files. Here is my hot key configuration:
[
{
"caption": "Tmpl: Create python",
"command": "sublime_tmpl",
"keys": ["ctrl+alt+p"], "args": {"type": "python"}
},
{
"keys":["f1"],
"caption": "SublimeREPL: Python",
"command": "run_existing_window_command", "args":
{
"id": "repl_python",
"file": "config/Python/Main.sublime-menu"
}
},
{
"keys":["f2"],
"caption": "SublimeREPL: Python - RUN current file",
"command": "run_existing_window_command", "args":
{
"id": "repl_python_run",
"file": "config/Python/Main.sublime-menu"
}
},
]
When I press F2 or F1, there is nothing happened.

It appears that Sublime Text 3 build 3200 has broken the run_existing_window_command command. As alluded to in this answer the solution is to instead invoke the command that the SublimeREPL menu item is using.
If you navigate to your Sublime Text 3 packages directory (AppData/Roaming/Sublime Text 3/ by default on Windows), you can see the packages you have installed. From this directory, if you open SublimeREPL/config/Python/Main.sublime-menu, you'll see a big ole json file that looks something like this:
[
{
"id": "tools",
"children":
[{
"caption": "SublimeREPL",
"mnemonic": "R",
"id": "SublimeREPL",
"children":
[
{"caption": "Python",
"id": "Python",
"children":[
{"command": "repl_open",
"caption": "Python",
"id": "repl_python",
"mnemonic": "P",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python", "-i", "-u"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
}

]}
]
}]
}
]
Notice that the innermost children key is a list of dictionaries with commands and args. We're going to copy those into the sublime-keymap file and replace the command and args that are already there. For example, your shortcut to open a python REPL would now look like:
"keys": ["f1"],
"command": "repl_open",
"args": {
"type": "subprocess",
"encoding": "utf8",
"cmd": ["python", "-u", "$file_basename"],
"cwd": "$file_path",
"syntax": "Packages/Python/Python.tmLanguage",
"external_id": "python",
"extend_env": {"PYTHONIOENCODING": "utf-8"}
}
Hitting F1 should now work like it used to.
