This must be a dumb doubt for sure
Im asking here atlast after I coudnt find solution anywhere... I'm intermediate in python and completed until chapter 5 in rust
Im trying to use python in rust while using the example i couldnt find out how to solve this...

Maybe its this because I didnt know how to do this step i checked out py03 example which suggests just installing python in ubuntu but nothing about in windows and while i just tested installing python using wsl it quite didnt work thats why

Did you install Rust for Windows or WSL? I imagine that PyO3 will want the WSL version of Python when you're running Rust inside WSL and the Windows version of Python when you're running Rust outside of WSL.

Your cpythontest3.exe suggests you're running for a non-WSL target, so you need a non-WSL Python.

Hey ssokolow I have all rust tools & python installed in both wsl and windows..//
and the error im showing here is while using windows powershell ie windows and actually what i was actually confused about is i have python in installed in windows from beginning so i didnt install any specific tools so like do i need to have some other executable or something?

The error indicates that cpythontest3.exe cannot find python3x.dll (where x depends on the python version used at build time, which for rust-cpython you can control with PYTHON_SYS_EXECUTABLE).

Window searches for required libraries only in the application directory, PATH and the windows system directory. Unlike Linux, there is no concept of a RUNPATH stored in the executable (which is how the python library gets found on Linux).
So unless you copy your executable into the same directory as your python installation, the only way to get it running is to add your python installation to the PATH.
