Python makes strange multiple directories

I have the following problem. I want to write a script for automatic folder structure creation defined inside a txt. However the following code creates strange multiple directories where one directory end with ?

[centos7@localhost table01]$ ls
01_lay   02_model   03_rig   04_texture   05_shading   references?
01_lay?  02_model?  03_rig?  04_texture?  05_shading?

An extract from the txt file used to create the folders:

.
./03_rig
./03_rig/release
./03_rig/working
./05_shading
./05_shading/release
./05_shading/working

Here is the code:

import os

#Global Variables
pathToProject = "/run/media/centos7/Data/Programming/Pipeline/SampleProject"
pathToPipeline = "/run/media/centos7/Data/Programming/Pipeline/Pipeline"

allowedTypes = ["asset_character", "asset_prop", "asset_dmp",  "scene", "shot"]

def createFolders(type, name):
    if type in allowedTypes:
        if type == "asset_character":
            pass
        elif type == "asset_prop":
            pathToCreateInside = os.path.join(pathToProject, "03_assets/prop/"+name)
            os.mkdir(pathToCreateInside)
            pathToTxt = os.path.join(pathToPipeline, "create_folders/folder_setups/asset_cg.txt")
            if os.path.isdir(pathToCreateInside) == True and os.path.isfile(pathToTxt) == True:
                makeDirStructure(pathToCreateInside, pathToTxt)
            else:
                print pathToTxt
                print pathToCreateInside
                print "Error: Folder or file does not exist "
        elif type == "asset_dmp":
            pass
        elif type == "scene":
            pass
        elif type == "shot":
            pass

    else:
        print "Only the following foldertypes are accepeted: ", allowedTypes

def makeDirStructure(pathToCreateInside, pathToTxt):
    with open(pathToTxt) as f:
        next(f)
        for path in f:
            try:
                os.makedirs(os.path.join(pathToCreateInside, path[2:]))
            except OSError:
                print ("Creation of the directory %s failed" % path)

createFolders("asset_prop","table01")

Update: The default text editor that comes with linux doesn't show any whitespace at the end of the line, while the nano editor allows me to jump into a sort of whitespace like position (I haven't used cli editors tho, so I don't know if it is a feature to do that or if the character really exists) WHY the hell wouldn't the default editor not show these characters? That could be so dangerous! By the way the txt was created with the command find . -type d > output.txt which makes it even stranger that linux does this. Any explanation?

I bet the character isn't a question mark, that's just ls's way of telling you that there's an unprintable character. The unprintable character in question is a carriage return character (CR, commonly represented as \r or \015 or ^M).

Unix uses the LF character (\n, \012, ^J) as a line terminator (i.e. every line consists of its printable characters followed by LF).

Update:

Alright, I found where you're erring, its the name of the txt file. You see after every name on the of the file, you have a trailing white-space, which is possibly causing the error since you cannot have a trailing white-space at the end of a folder name. Remove the white-spaces at end of every name in the txt file, and see it work, or even better, use the strip() string function where you're reading the names, eg. path.strip(). ;)
