I want to compile a py file to mpy

[Jhordan78]

This is a code for an antivirus that when it detects a virus hash but an error appears then I have to convert it to mpy because this is pyton code
This code
import hashlib
def calcular_hash(archivo):
"""Calcula el hash SHA256 de un archivo."""
sha256_hash = hashlib.sha256()
with open(archivo, "rb") as f:
# Leer y actualizar el hash en bloques de 4K
for byte_block in iter(lambda: f.read(4096), b""):
sha256_hash.update(byte_block)
return sha256_hash.hexdigest()
def verificar_virus(hash_archivo, db_virus):
"""Verifica si el hash del archivo está en la base de datos de virus."""
return hash_archivo in db_virus

Lista de hashes de virus conocidos (ejemplo)

db_virus_conocidos = [
"hash_virus_1",
"hash_virus_2",
"hash_virus_3",
]

Asignar ruta

ruta = "myfile.txt"

Calcula el hash del archivo

hash_del_archivo = calcular_hash(ruta)
print(f'El hash del archivo {ruta} es {hash_del_archivo}')

Verificar si el archivo es un virus conocido

es_virus = verificar_virus(hash_del_archivo, db_virus_conocidos)
if es_virus:
print("Alerta: El archivo es un virus conocido.")
else:
print("El archivo no coincide con ningún virus conocido en la base de datos.")
The errors is
este hash_del_archivo = calcular_hash(ruta) y with open(archivo, "rb") as f:
It.says
File "", line 27, in
File "", line 6, in calcular_hash

You can build the .mpy bytecode file using the mpy-cross module, like this:

pip3 install mpy-cross
python3 -m mpy_cross $SRC_FILE

where $SRC_FILE is the name of the original .py file.

You can also do this automatically as part of a GitHub Action. See this discussion topic for details.

very kind to answer me but I have a question as I am new in this area I download pypi.org and install it as a plugging from thonny and compile it I found it as mpy - cross-v6 but this one with this same pip shows the same errors it could be more detailed is that I am very new in this area El mar, 19 de dic de 2023, 7:47 a. m., Dave ***@***.***> escribió:

I have not tried using it from Thonny, so I don't know if it's possible. However, from Windows command-line, this works:

py.exe -m pip install mpy-cross
py.exe -m mpy_cross sourcefile.py

I'm using Python 3.12 installed from the MSI package at https://www.python.org/downloads/

[Jhordan78]

WITH WHICH IDE COMPILER YOUR ESP32 PROGRAMS THEN I JUST TYPE py.exe -m mpy_cross .\thimble.py IN CMD AND IT ALREADY LOADS? El mar, 19 dic 2023 a las 10:42, Dave ***@***.***>) escribió:

Sorry, the .\thimble.py was a copy-paste mistake in my example. It should be whatever the name of your MicroPython file is.

I'm using mpy_cross to pre-compile a module I have written into byte code. The resulting .mpy file goes in the /lib directory on my microcontroller. For the example of thimble.py, when I do from thimble import Thimble in my main.py, it will load the thimble.mpy file.

This is not required, but does speed up module loading. It is also more space efficient. The resulting .mpy is less than 1/4 the size of the original. You don't need to do this for most MicroPython programs you write.

Substitute your program name for .\thimble.py. That was just my example.

[Jhordan78]

Suddenly you have a video on how to do it, I don't understand much El mar, 19 dic 2023 a las 11:12, Dave ***@***.***>) escribió:

I'm not aware of any videos. I got my information from searching here and there. I don't recall the sources. It basically comes down to this:

Windows

py.exe -m pip install mpy-cross
py.exe -m mpy_cross sourcefile.py

Linux

pip3 install mpy-cross
python3 -m mpy_cross sourcefile.py

In the end, you get sourcefile.mpy

[Jhordan78]

esto es lo que me aparece en instalar en cmd el pluggin py.exe -m mpy_cross sourcefile.py se puede solamente con el primero py.exe -m pip install mpy-cross C:\Users\J. Zapata>py.exe -m mpy_cross sourcefile.py OSError: (2, "can't open sourcefile.py") What programs do you run the programs with? El mar, 19 dic 2023 a las 11:22, Dave ***@***.***>) escribió:

Substitute the name of your MicroPython file in place of sourcefile.py

[Jhordan78]

thank you for sharing your generous time with me that sourcefile.py does not install in cmd and I change the name in thonny as it says sourcefile.py [image: image.png] El mar, 19 dic 2023 a las 11:47, Dave ***@***.***>) escribió:
