SyntaxError: invalid syntax ??

[snippsat]

this is an old PI3 , maybe I can't make it work ?

Which version did you install?
The newest is python 3.10 or python 3.9.5 as used in tutorial?
What folder do cd into after extracted files?
To run directly

1 2 3

python3.10 myscript.py # Or python3.9 myscript.py

but how can I do it for this part:

1 2 3

data_byte = b'123' data_temp = ["{:02X}".format(byte) for byte in data_byte] print(data_temp)

Output:
['31', '32', '33']

I have install the latest

1	Python-3.9.10

and it's in this folder

1	/Python-3.9.10 $

when I try to run it
I get error "ModuleNotFound "

1 2 3 4 5

python3.9 ReadCanbus.py Traceback (most recent call last):   File "/home/pi/ReadCanbus.py", line 1, in <module>     import can ModuleNotFoundError: No module named 'can'

while running python3 - will work

and I did what you told me - and it's seem to be working

so thank you !

I have install the latest

1	Python-3.9.10

That's fine,as info the lasted version is Python 3.10

I get error "ModuleNotFound "

When have a new version most install all 3-party packages that you use to this version.
Do a test of python and pip from command line,that use right version.

1 2 3 4 5 6 7

python --version # Or python3 --version    pip --version # or pip3 --version

Installation python-can 3.3.4

1 2 3

pip install python-can # Or python3 -m pip install python-can

when I run the code using python3 - everything is working
isn't Python3.9 need to use the same packages from pip3 as Python3 ?

[snippsat]

Is still use the old version
Try:

1	python3.9 --version

If that point to Python 3.9
Install with.

1	python3.9 -m pip install python-can

Then you most always use python3.9 my_script.py

Look search for alias change if want all to point to one version.

I get error

1 2	ERROR: Could not find a version that satisfies the requirement python-can (from versions: none) ERROR: No matching distribution found for python-can

starnge

but never mind - this is an old PI, just for testing
thank you for all the help and the answer

I didn't know that python3.9 is not the same as python 3 and 3.5
I thought it will be update auto

Thanks you!
