Hello Everyone,
I have a 2d array something like :

[50,100,150]
[2000,1000,2000]

I want to save this array in a text file, for this I’m using the following code:

func save(content, filename : String):
var file = File.new()
if (file.open(str("res://R//", filename, ".txt"), File.WRITE)== OK):
    for i in range(content.size()):
        file.store_line(str(content[i]) + "\r")
    file.close()

The problem is that the bracket appear in the text file. How can I remove from the text file

To create the 2D array content I’m using this

func createArrayForTXT():
   var content = []

   content.append("a")
   var array_ = ["b"]
   content.append([])
   for  x in range(array1.size()):
	   array_.append(array1[x])
   array_.append(0)
   content[1].append(array_join(array_,","))
   var fileName : String
   for  x in range(aRRAY2.size()):
	  content.append([])
	  array_ = [aRRAY2[aRRAY2.size()  - 1 - x]]
	  for  y in range(array1.size()):
	  	  array_.append(y+x+1)
	  array_.append(0)
	  content[x+2].append(array_join(array_,","))# + "\r")
	  fileName = "textFile1"

   save(content, fileName)

the result of this is

a
[b,1,2,3,4,5,0]
[50,1,2,3,4,5,0]
[40,2,3,4,5,6,0]
[30,3,4,5,6,7,0]
[20,4,5,6,7,8,0]
[10,5,6,7,8,9,0]

and what I need is

a
b,1,2,3,4,5,0
50,1,2,3,4,5,0
40,2,3,4,5,6,0
30,3,4,5,6,7,0
20,4,5,6,7,8,0
10,5,6,7,8,9,0

Thanks!!

I use this

func save(content, filename : String):
var file = File.new()
if (file.open(str("res://Results//", filename, ".txt"), File.WRITE)== OK):
	
	for i in range(content.size()):
		if i == 0:
			file.store_line(str(content[i]) + "\r")
		else:
			file.store_line(PoolStringArray(content[i]).join(",") + "\r")

	file.close()
