How can I call a python function from an advanced scripting voice command in Dragon NaturallySpeaking?

How can I call a python function from an advanced scripting voice command in Dragon NaturallySpeaking?
I don't want to use a third-party application such as dragonfly or NatLink (paper).

So, one way is to compile it. You can put a bunch of functions that do different things all into the same program and pass along appropriate arguments to select the function you want, and pass the parameters along. Returning the result can be tricky, though, but I usually use the Clipboard (so copy the py output to clip and read from clip in Dragon). Multi-word params need to have spaces escaped (%20) and process it inside your py.
Something like this:
ShellExecute "path\program.exe myFunc myPar1, my%20Par%202", 6 ' 6 runs minimized
Wait 1
myVar = Clipboard
Hth,

This is just a suggestion on how to solve this problem. I don't know where else to put this. I'd put it in a comment, but it allows no screenshots. Please edit and suggest as you wish.
There is answer on SO that deals with calling Python from Excel, which is a similar concept: https://stackoverflow.com/a/3569988/2101890. I am trying to use that here but don't know how.
When using commands in another programming language, you can sometimes add them by adding a reference in the MyCommands Editor. You can reference DLLs and other "stuff". Some references to libraries appear automatically. I've installed Python and hoped to find Python in the References, but no such luck:
There is no Python entry here that I can find. You may have better luck. If you do find something, check the box and see if you can add python commands without causing an error when saving the command.
Maybe you can browse to %localappdata%\Programs\Python\Python36\ and add some of the DLLs from there and call Python commands from there. Or try getting it to work in the way described under 1.

How to hot swap the current file in python

I am trying to hot swap a file in python. I am creating a game that takes a really long time to load. But I don't want to reload it every time. I am trying to change some code while the programme is in runtime.
For example:
I want to change this:
while True:
print("Hello")
to this while in runtime:
while True:
print("Hello World")
I looked hot swapping up for python and all of them are answers that I am not looking for. All the other answers change modules. I want to change the current file. Like java in eclipse. Please help!

I want to change the current file. Like java in eclipse.
When you modify Java code in Eclipse, the code is not currently running. In reality, Eclipse has a Java compiler built-in, which attempts to compile your code as you type it. That's how Eclipse is able to give you such fast feedback about syntax errors and type errors in your code. But it can't give you any information about the runtime behaviour of your code (whether or not it produces the right answer), because it doesn't run the code! You need to press the Run button for that.
So I think the question you really want to ask is not "Can I dynamically modify Python code?" (the answer to that is "Yes, but it's complicated and has caveats and is not a good idea") but "Does there exist a Python IDE which can give me feedback about syntax errors while I type?" The answer to that is an emphatic "Yes!". There's an extremely comprehensive list of options in this answer.

You can use dynamic execution using exec function.
Store the code you want to execute in a string and change it during runtime.

How do I read a prompt/output from another python script and return input?

I'm looking to test a batch of python scripts made by different users. They're behaving in the same manor, asking for user input, it will be random but within a range I know ahead of time.
I want to write a script that executes each one of them, each of the scripts will give a prompt. Given the prompt, I want my script to respond accordingly. Is this even possible? How would I go about this?
I'd also like to detect errors, like the ones thrown by IDLE and log them to a file. Any ideas?

Using Python 3 with Python 2

I have a Python 3 file. I want to use an open-source tool on the internet (nltk), but unfortunately it only supports Python 2. There is no way for me to convert it to Python 3, nor can I convert my Python 3 file to Python 2.
If the user does not give a certain argument (on argparse) then I do something in my file. If the user does give a certain argument, however, I need to use nltk.
Writing a Python 2 script that uses nltk and then executing script that in my Python 3 script
My current idea is to write a script in Python 2 that does what I want with nltk and then run that from my current Python 3 script. However, I don't actually know how to do this.
I found this code: os.system(command) and so I will modify it to be os.system("python py2.py") (where py2.py is my newly written Python 2 file).
I'm not sure if that will work.
I also don't know if that is the most efficient way to solve my problem. I cannot find any information about it on the internet.
The data transferred will probably be quite large. Currently, my test data is about 6600 lines, utf-8. Functionality is more important than how long it takes (to a certain extent) in my case.
Also, how would I pass values from my Python 2 script to my Python 3 script?
Thanks

Is there any other way to do this?
Well, if you're sure you can't convert your script to Python 2, then having one script call the other by running the Python interpreter probably is the best way. (And, this being Python, the best way is, or at least should be, the only way.)
But are you sure? Between the six module, the 3to2 tool, and __future__ statements, it may not be as hard as you think.
Anyway, if you do need to have one script call the other, you should almost never use os.system. As the docs for that function say:
The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. See the Replacing Older Functions with the subprocess Module section in the subprocess documentation for some helpful recipes.
The simplest version is this:
subprocess.check_call(["python", "py2.py"])
This runs your script, waits for it to finish, and raises an exception if the script returns failure—basically, what you wanted to do with os.system, but better. (For example, it doesn't spawn an unnecessary extra shell, it takes care of error handling, etc.)
That assumes whatever other data you need to share is being shared in some implicit, external way (e.g., by accessing files with the same name). You might be better off passing data to py2.py as command-line arguments and/or stdin, passing data back as via stdout, or even opening an explicit pipe or socket to pass things over. Without knowing more about exactly what you need to do, it's hard to suggest anything, but the docs, especially the section Replacing Older Functions with the subprocess Module have lots of discussion on the options.
To give you an idea, here's a simple example: to pass one of your filename arguments to py2.py, and then get data back from py2.py to py3.py, just have py3.py do this:
py2output = subprocess.check_output(["python", "py2.py", my_args[0]])
And then in py2.py, just print whatever you want to send back.

The Anyone hear when NLTK 3.0 will be out? here in SO points out that...
There's a Python 3 branch:
https://github.com/nltk/nltk/tree/nltk-py3k
The answer is from July 2011. It could be improved since then.
I have just looked at https://github.com/nltk/nltk. There is at least the document that talks about Python 3 port related things https://github.com/nltk/nltk/blob/2and3/web/dev/python3porting.rst.
Here is a longer discussion on NLTK and Python 3 that you may be interested in.
And the Grants to Assist Kivy, NLTK in Porting to Python 3 (published 3 days ago) is directly related to the problem.

comparing batch to python commands?

Ok i have these commands used in batch and i wanted to know the commands in python that would have a similar affect, just to be clear i dont want to just use os.system("command here") for each of them. For example in batch if you wanted a list of commands you would type help but in python you would type help() and then modules... I am not trying to use batch in a python script, i just wanna know the similarities in both languages. Like in english you say " Hello" but in french you say "Bonjour" not mix the two languages. (heres the list of commands/functions id like to know:
change the current directory
clear the screen in the console
change the prompt to something other than >>>
how to make a loop function
redirections/pipes
start an exteral program (like notepad or paint) from within a script
how to call or import another python script
how to get help with a specific module without having to type help()
#8: (in batch it would be command /?)
EDITED COMPLETELY
Thanks in Adnvance!

You can't just mechanically translate batch script to Python and hope that it works. It's a different language, with different idioms and ways of doing things, not to mention the different purpose.
I've listed some functions related to what you want below, but there's no substitute for just going and learning Python!
os.chdir
os.system("cls") is probably the simplest solution
Change sys.ps1 and sys.ps2.
Nope, there are no gotos in Python. Use for and while loops instead.
Doesn't make sense, use Python's IO instead.
subprocess.Popen
Doesn't make sense, use import or subprocess.Popen instead.
help

Most of the things you've mentioned (start, cls etc.) are not "batch commands", they're executable programs which perform certain tasks. The DOS "shell" simply executes these when it encounters them in a file. In this sense, "python" is the equivalent of a single executable (like cls).
Now that that's clear, cd (and most other OS specific tasks) are accomplished using the os module. There's no single Python statement to clear the screen - that would be wasteful. Changing the prompt of the python interpreter can be done by assigning to sys.ps1. Loops are done using while or for. Redirection doesn't happen. YOu can however use the subprocess module to run subcommands and send their outputs to files or other streams. Starting commands is done using the subprocess.Popen function. For getting help, you can either do help("command") or if you're using ipython, just say command? and hit enter.
You should really go through the tutorial rather than trying to map batch commands to Python.

The Python docs are excellent, and are the place to start. For doing shell-script like things, you'll want to check out:
http://docs.python.org/library/os.html?module-os
http://docs.python.org/library/os.path.html#module-os.path
http://docs.python.org/library/shutil.html#module-shutil
http://docs.python.org/library/subprocess.html#module-subprocess

Python is not a system shell, Python is a multi-paradigm programming language.
If you want to compare .bat with anything, compare it with sh or bash. (You can have those on various platforms too - for example, sh for windows is in the MinGW package).

I am pretty much facing the same problem as you, daniel11. As a solution, I am learning BATCH commands and their meaning. After I understand those, I am going to write a program in Python that does the same or accomplishes the same task.
Thanks to Adam V. and katrielatex for their insight and suggestions.
