cannot write to file if I run .exe

I am writing a short program where I want to write an array full of street names to a .txt file. Everyting works fine, but if I convert the python code to a .exe with pyinstaller, I cant write to a new .txt file anymore. Why does this happen?
with open(f"C:\\Users\\auser\\Desktop\\tset\\{txtname}.txt", "a") as txt_file:
for line in new_addresses:
txt_file.write(line + "\n")
txt_file.close()
this is how I create the .exe:
pyinstaller --onefile streets.py
Traceback (most recent call last):
File "streets.py", line 65, in
PermissionError: [Errno 13] Permission denied: 'C:\Users\auser\Desktop\tset\test.txt'
[7048] Failed to execute script rewriteword

I got this to work now. My anti virus program was blocking for some reason the execution.

Permission error without a file extension

I have an python program that scans all files in a directory, but when I want to open a file with no extension like C:\path\to\file\actual file, then python gives me a permission denied error.How can I fix that?
What I mean with no extension is that it does not have .exe or .txt or something like that.How can I read files without adding extensions to the files manually?
This is the full error:
Traceback (most recent call last):
File "scan.py", line 152, in <module>
file = open(i,'r')
PermissionError: [Errno 13] Permission denied: 'C:\\path\\to\\file\\my_file'

Ok, I have zero idea why it does not work other than what my comment stated, however this program will work for windows.
import os
s = "H:\path\to\file\ActualFile"
for subdir, dirs, files in os.walk(s):
for file in files:
try:
GatheredFiles = (os.path.join(subdir, file))
except PermissionError:
print("You do not have permision to go in here"))
break
Edit: added the try statement

Pyinstaller Error Bundling Egg Files FileNotFoundError: [Errno 2] No such file or directory

I am attempting to convert my python file (.py) into a Windows executable (.exe). To do this, I am using Pyinstaller. My python includes the module PyBluez for Bluetooth capabilities. When I run the command pyinstaller <path> -F from the directory of the py file, it gives an error:
FileNotFoundError: [Errno 2] No such file or directory: 'c:\users\X\appdata\local\programs\python\python37-32\lib\site-packages\pybluez-0.22-py3.7-win32.egg\bluetooth\widcomm.py'
After quite a bit of research, I am unable to figure out what is wrong with my program. Do I need to specifically specify where to find the egg file? If so, How would I do that? Thank you! Also, I tried to use cx_Freeze and it also gave an error about the bluetooth module:
Traceback (most recent call last):
File "C:\Users\X\AppData\Local\Programs\Python\Python37\lib\site-packages\cx_Freeze\initscripts__startup__.py", line 14, in run
module.run()
File "C:\Users\X\AppData\Local\Programs\Python\Python37\lib\site-packages\cx_Freeze\initscripts\Console.py", line 26, in run
exec(code, m.dict)
File "BuzzerBeater.py", line 3, in
ModuleNotFoundError: No module named 'bluetooth'

I had the same problem, and managed to solve it by unzipping the .egg file to a folder with the same name (including .egg in the folder name), in my case C:\Users\X\AppData\Local\Programs\Python\Python37\Lib\site-packages\PyBluez-0.22-py3.7-win-amd64.egg\.

Python script requires permission to copy files

I am trying to write a python script to copy some files from one place to another like this:
os.system('cp file/path/a file/path/b')
when I run this within the python prompt it works just fine. But if I put this in a python script it fails with the error
cp: cannot create regular file 'file/path/b': Permission denied
I am getting this error even when I run the script using sudo permissions i.e. sudo ./mysript.py
So what is going on here and is it possible for me to fix this?
EDIT 1:
Following the suggestions of #kungphu and #ShadowRanger I switched from using os.system to using shutil.copy. The problem persists however I am now getting a different error:
Traceback (most recent call last):
File "./myscript.py", line 21, in <module>
shutil.copy('/absolute/file/path/a', '/absolute/file/path/b')
File "/python/lib/python2.6/shutil.py", line 84, in copy
copyfile(src, dst)
File "/python/lib/python2.6/shutil.py", line 50, in copyfile
with open(src, 'rb') as fsrc:
IOError: [Errno 13] Permission denied: '/absolute/file/path/a'

Python IOError: No such file or directory

I have a python program which inputs a .wav file name from the user, does some filtering and writes the output to another .wav file. The programs works perfectly well when I run it using the interpreter. But when I run the program using command prompt, it prompts for the input audio filename, but when I type the .wav filename and press enter, I get the following error:
Traceback (most recent call last):
File "C:\python_audio\stereo.py", line 15, in <module>
(fs, x) = read(audio_in,'rb')
File "C:\Python27\Lib\site-packages\scipy\io\wavfile.py", line 155, in read
fid = open(filename, 'rb')
IOError: [Errno 2] No such file or directory: 'chostakovitch.wav'
The python program stereo.py and the .wav file (chostakovitch.wav) are in the path C:\python_audio, and I have added this path as an environment variable.
But I can't figure out why I am still getting this error?
