问题 My friend and I are making chess AIs in Python, but we're running into a mysterious problem with enums. We encode the piece types in an enum like so: Piece.py: from enum import Enum class PieceType(Enum): type_one = 1 ... def recognise_type(my_type): print("Passed ", my_type) if my_type is PieceType.type_one: print("Type One") else: print("Type not recognised") We ask the AI for a piece (for promoting a pawn for instance) and call recognise_type: ai.py: import Piece def get_promotion():

问题 Im trying to figure out how to include a .pyc file in a python script. For example my script is called: myscript.py and the script I would like to include is called: included_script.pyc So, do I just use: import included_script And will that automatically execute the included_script.pyc ?

问题 I'm cleaning up a project that was refactored into smaller .py files. I noticed that a lot of modules are being imported again and again in various files.

问题 I'm trying to read xls file into R using readxl::read_excel , but it's giving the following errors: Error: filepath: //.../data.xls libxls error: Unable to parse file also tried readxl::excel_sheets(), but same errors. readxl::format_from_ext(path) gives "xls" Also tried re-installing readxl packages, didn't work for me.

问题 I'm new to js, vue & nuxt so quite confused about what is the correct and best way to import a script / module / component into an HTML page and run it. For example, I know that this works with an event listener in the js script: <template> <div> <button id="importJS">Go!</button> </div> <template> <script src="~/index.js"></script> But is something like this better?: @import "~/index.js" <template> <div> <button id="importJS">Go!</button> </div> <template> And / or should only the main
