Python lists output vs Dynamo

Developers

Hi guys!

I am trying to develop a python script that allows me to add a number to the Revision Clouds Mark parameter according to its Comments (same string Comments). The strings will be then formatted so it can be exported to Excel, generate a txt. file that can easily be pasted on a sheet.

I was able to do this through a 100% Dynamo script, but I would like to mimic the same behavior in Python, as I am learning the language. In Python the output is correct according to my needs, but as soon as I paste it to the Python Dynamo node, my output turns out to be different (see pic).

Is this due to the fact that I am using some extra Python modules to make my life easier? :face_with_hand_over_mouth:

This is my Python code which I copy/paste to Dynamo Python node. Just changed the input and output in the Python node.

import itertools 
from collections import Counter

comments = [
	"wand aangepast", "plafond verlaagd", "kozijn", "kozijn",
	"kozijn", "plafond verlaagd", "morgen", "kozijn",
	 "sloop", "sloop", "niks", "sloop"
	]
items_repeated = []
items_repeated_amount_total = []
unique_mark = []

# Making that list a unique element list
for item in comments:
	if item not in items_repeated:
		items_repeated.append(item)

print("Items repeated are :",items_repeated)
items_repeated_amount_total = len(items_repeated)

# Making a list representing the numbering base 
# So it can be used when looping according to the amount
# Of same comments
for mark in range(1, items_repeated_amount_total + 1):
	unique_mark.append(mark)
#print(mark)
print("Unique mark is: ", unique_mark)

# Using Counter class from collections module to check 
# The ammount of comment repetitions in the list	
dic_comments = Counter(comments)
print(dic_comments)
# Convert dictionary values to list
dic_values = []
for key, value in dic_comments.items():
	dic_values.append(value)
print("Number of repetitions of mark values: ", dic_values)

# Cycle the unique mark values according to the (converted) dictionary values
# That represent the amount of same comments
mark_sequence = list(itertools.chain(*(itertools.repeat(elem, n) 
													for elem, n in zip(unique_mark, dic_values))))
print("Items to be inserted in the revClouds: ", mark_sequence)

Any tip in the right way would be wonderful. Thank you in advance

hello @JFK

a solution without modules

import sys

comments = [
	"wand aangepast", "plafond verlaagd", "kozijn", "kozijn",
	"kozijn", "plafond verlaagd", "morgen", "kozijn",
	 "sloop", "sloop", "niks", "sloop"
	]
	
uniqueList = [x for i, x in enumerate(comments) if i == comments.index(x)]
#create a mark integer into a list and multiply by the number of instance 
listCount = [[idx + 1] * comments.count(x) for idx, x in enumerate(uniqueList)]
#flat the list
final = sum(listCount, [])
OUT = final

@c.poupin thank you. It works like a charm.

I will study the code to see if I can learn something from it.
