All is working fine now. I had always assumed that Idle and pip were installed with the standard library and not have to be separately installed.

I assumed it was always installed with the standard library, and every time I upgrade to a new version of Mageia, I have the same problem and can never remember what I have done before. Pat of the problem for me is that idle is automatically installed with the Windows version. I got a lot of help from the Mageia group and now have all installed.

[Tutor] missing idlelib and pip
The python distribution for the Mageia 6 update does not include idlelib or pip. Please tell me where to find them to add. This seems to be a constant issue with linux distributions of python. I tried to have idlelib added to the Mageia 6 update and all I got was vague noise and nothing done.

I have a script that reads sensor values gathered by an Arduino board
from
serial as a dictionary, said values to later be used in the AI for Nav
Control. Here's the script:
#!/usr/bin/python
def sensorRead():
import serial
from time import sleep
sensors = {}
sensors = dict.fromkeys('Sonar1 Sonar2 Sonar3 Sonar4 Dewpoint
Temperature Humidity Light'.split())
arduino = serial.Serial('/dev/ttyACM0', 9600)
sleep(1)
line = arduino.readline().strip()
line = line.lstrip('{').rstrip('}').strip()
d = {}
for item in line.split(','):
item = item.strip()
key, value = item.split(':')
key = key.strip()
value = value.strip()
d[key]=int(value)
return d
The script works great with one exception. I understand the problem, I'm
just not sure how to address it. The problem is:
The Arduino runs on a constant loop, it reads each sensor, sends the key
and the value to the serial bus in format for python to read it as a
dictionary, lather, rinse, repeat.
Python querries the bus when told. Usually the python script gets the
full
dictionary (all 8 values with keys, brackets etc) but sometimes it
doesn't.
Sometimes it only gets the last few values, sometimes it gets nothing or
misses a bracket and throws an error. This makes sense. They are not in
sync.
What I need to figure out how to do is have the python script wait until
the next round of values as signified by the opening bracket { or check
that it has all 8 values and if not retry or something.
There should be no sync issue here. The readline method should read from
the
serial port until it reaches an EOL character, then return the whole line
(i.e., your sleep(1) should be removed since readline() already waits for
input).
From what you're describing, the real issue seems to be on the side of the
sender. Are you sure, it terminates each line with \n as it should? Where
is
that code coming from?
Best,
Wolfgang

I also suspect sleep doesn't work. Two better options would be:
1. read/loop until line terminator,
2. Use serial signals, i.e., RTS/DTS if possible.
