Python IDLE 3.6.2 on WIn7 vs Pyhton 3 IDLE raspberry - djdan_23 - Sep-07-2017
Hi! all.
First question:
I have a small starter program that bugs me. I took this one on the net
and work well in Raspberry Pi3 Stretch & Python 2.7.13, in command line
like: python test01.py , it print too, the version of running GPIO = 0.6.3
But when I try it with Python 3.6.2 in Raspberry or on the Python 3.6.2 on Windows 7
it give me this on both:
Traceback (most recent call last):
File "test01.py", line 1, in <module>
import RPi.GPIO as GPIO
ModuleNotFoundError: No module named 'RPi'
What can I do to be able to make it work.
Second question:
I build the Python 3.6.2 on rapsberry pi3 "Raspbian GNU/Linux 9 (stretch)"
using this internet address as a guide:
"bohdan-danishevsky.blogspot.ca/2017/01/building-python-360-on-raspberry-pi-3.html"
Everything works well when I type python3.6 , But If I type python, then it's 2.7.13.
What ca I do to have version 3.6.2 when I type python.
Thanks

while True:
GPIO.output(LedPin, GPIO.HIGH) # led on

you will need to install the python 3 RPi.GPIO package.
do you have pip on the pi?
if so, the command will be:
pip3 install RPi.GPIO

To answer your second question python2.7 is installed on the raspberry pi by default.
Typing:
which python
which python3
will return the relative path. You can create a symlink but this is not advisable
as any other software that requires python2.7 will break.
You should be able to run python 3.6 just by typing
python3
On debian 8 this defaults to python3.4.3, I've not upgraded to DEbian 9 yet.

Quote:Everything works well when I type python3.6 , But If I type python, then it's 2.7.13the paths are messed up. Don't know how to fix this in firmware.
you may have to specifically use python
python3.6 myscript.py

Hey! thanks
I thought that since it appears to be 0.6.3 on the default Python 2.7.13,
it was the same module used bu the Python 3.6.2. My mistake.
I used "sudo pip3 install RPi.GPIO" and everything works properly.

Good!
