I just started switching from R to python, and may I ask about some very basic questions?
There are two nice properties that Rstudio has, which I haven't figure out how to do with python. For example, I'm trying to use the dot product function such as numpy.array([1,2]).dot(numpy.array([3,4])).
Problem 1: In R, if I move the cursor into a function, the possible arguments that I can potentially use will be shown, as demonstrated in the figure below. However, I don't see this in python (jupyter lab).
Problem 2: for the help document regarding the function, in R I would just type ?functionName(), but in python I don't really know how to get the help documents. help(numpy.array) returns me a full list of everything, and I was wondering if there is a way for it to return only the help document for the dot product function?
Problem 1: you can press Shift+Tab after placing cursor on the function in question for a snippet of documentation. Press Shift+Tab+Tab for a more detailed one.
Problem 2: you can run the same command as R but just drop the brackets.
e.g. ?numpy.dot

Is there a way to exclude parameters being autocompleted in IntelliSense?
I have used IntelliJ before, and I recently switched over to VS Code. Upon switching and installing IntelliSense, I have had issues with some of the autocompletes. For example, on tab completion of the print function, I would just expect it to complete as:
print()
but it instead completes as:
print(sep=..., end=..., file=..., flush=...)
Only for some functions does the autocomplete include the parameter suggestions, and not for other, and I cant seem to figure out why. I tried looking through the settings but without much luck. Any help?
I am trying to find a way to edit and run a sequence of python scripts in a less manual way.
For context, I am running a series of simulations, which consist in running three codes in order 10 times, making minor changes to each code every time. The problem I am encountering is that this process leads to easy mistakes and chaotic work.
These are the type of edits I have to make to each code.
- Modify input/output file name
- Change value of a parameter
What is the best practice to deal with this? I imagine that the best idea would be to write another python script that does all this. Is there a way to edit other python codes, from within a code, and run them?
I don't intend or want anyone to write a code for me. I just need to be pointed in a general direction. I have searched for ways to 'automatize' codes, but haven't yet been successful in finding a solution to my query (mainly the editing part).
Thanks!
The thing that can change (files or parameter values) should be able to be either passed in or injected. Could be from a command line parameter, configuration file, or method argument. This is the "general direction" I offer.
I'm new to Python and this is my first question here. Hope any of you guys will be able to help me out.
I'm trying to call values inside an object from an external program. The object that I'm trying to access is given in a class (as i uderstand it), and the name of the class may change according to X, see below:
External programs object and class information
I want to be able to call information from Phase_6 in this case, however it could be Phase_12 in another case. I was considering making a function where i could have the _'Number' as an input. But I can't seem to find any information of how to do such.
I was thinking of something like using +str(X), as I do when plotting. But as it is probably not a string, it doesn't work out.
My proposed code
Ive read that bpy in Blender may be able to replace the name of the class that i want to return, however I'm not sure if it'll work, and I dont want to switch editor :)
Hope you guys can help me out,
Joachim
Found the answer, one could use getattr.
x = 6
result = getattr(g_o, 'phase_'+str(x)).Info.SumMsf.value
Thanks anyway - And I'll work on the pictures

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,
Warning: This is not an answer. I am not a programmer. I don't know any Python and have no way of testing it.
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.
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.
