Bash script to find and list duplicate instances of python - linux

Question

I am trying to write a bash script to find duplicate instances of python scripts running on a Pi. The following script is working and identifies the Python (not Python3 intentionally) of duplicates instances of the same script. I get the PID as expected but I am not able to get the full path and name of the script.
I have created a couple instance of a script:
bms 9189 0.0 0.1 10592 7248 ? S 09:11 0:00 python -u /home/bms/Dev/APItest/APItest.py
bms 9192 0.0 0.1 10592 7188 ? S 09:12 0:00 python -u /home/bms/Dev/APItest/APItest.py
This is the output I get from the bash script:
Found 2 instances of -u:
PID: 9189, Script path: -u
PID: 9192, Script path: -u
Finished checking for duplicate Python scripts.
I was expecting to get an output like:
PID: 9189, Script path: home/bms/Dev/APItest/APItest.py
PID: 9192, Script path: home/bms/Dev/APItest/APItest.py
And this is the script I am using:
#!/bin/bash
# Get a list of all running Python processes
PYTHON_PROCESSES=$(ps aux | grep '[p]ython' | grep -v 'python3' | awk '{print $2}')
# Loop through the Python processes and count how many times each script is running
declare -A SCRIPT_COUNTS
declare -A SCRIPT_PIDS
for PID in $PYTHON_PROCESSES; do
CMD=$(ps -p $PID -o comm=)
if [ "$CMD" == "python" ]; then
SCRIPT_ARGS=$(ps -p $PID -o args=)
SCRIPT_PATH=$(echo "$SCRIPT_ARGS" | awk '{print $2}')
SCRIPT_NAME=${SCRIPT_PATH##*/}
if [ -z "${SCRIPT_COUNTS[$SCRIPT_NAME]}" ]; then
SCRIPT_COUNTS[$SCRIPT_NAME]=0
fi
((SCRIPT_COUNTS[$SCRIPT_NAME]++))
if [ -z "${SCRIPT_PIDS[$SCRIPT_NAME]}" ]; then
SCRIPT_PIDS[$SCRIPT_NAME]=""
fi
SCRIPT_PIDS[$SCRIPT_NAME]="${SCRIPT_PIDS[$SCRIPT_NAME]}$PID:$SCRIPT_PATH "
fi
done
# Loop through the script counts and print the names of any scripts that have duplicates
for SCRIPT_NAME in "${!SCRIPT_COUNTS[#]}"; do
COUNT=${SCRIPT_COUNTS[$SCRIPT_NAME]}
if [ $COUNT -gt 1 ]; then
echo "Found $COUNT instances of $SCRIPT_NAME:"
for INSTANCE in ${SCRIPT_PIDS[$SCRIPT_NAME]}; do
PID=${INSTANCE%%:*}
SCRIPT_PATH=${INSTANCE#*:}
echo "PID: $PID, Script path: $SCRIPT_PATH"
done
fi
done
echo "Finished checking for duplicate Python scripts."
Apologise if there is any misalignment in the code. Had to adjust it manually to fit it in the canvas.
My question is: what should I change to get the desired output ( PID plus full path and name of the duplicates).

Why not this simple awk ?
$ <INPUT> | awk '{print "PID: " $2 ", Script path: " $NF}' file
PID: 9189, Script path: /home/bms/Dev/APItest/APItest.py
PID: 9192, Script path: /home/bms/Dev/APItest/APItest.py
