Access Denied error in python when trying to remove directory - windows

Question

I'm trying to remove some directorys from my desktop.
The name of the directorys follow the format year+month (Ex.: 201808), i need to remove the directorys 2+ months before (Ex.: 201705, 201709, 201806).
Using the os.remove(path), the python return a error:
Traceback (most recent call last):
File "C:\Users\Usuario\Desktop\teste.py", line 36, in <module>
os.remove(caminhoPastaFinal)
PermissionError: [WinError 5] Acesso negado: 'C:\\Users\\Usuario\\Desktop\\Área de testes\\pasta1\\pasta2\\pasta3\\pasta4\\201712'
I tried to run the script as admin in the CMD, but i got the same error.
I'm using Windows 10.
Why i don't have permission to do that?
Follow the code:
import os
from datetime import *
def verificarNome(nomePasta):
mes=nomePasta[-2:]
ano=nomePasta[:-2]
if ano<anoAtual:
return True
elif mes<=mesAtual:
return True
return False
dataAtual = datetime.now()
anoAtual = str(dataAtual.year)
mesAtual = dataAtual.month
if mesAtual < 10:
mesAtual = "0"+str(mesAtual-2)
else:
mesAtual = str(mesAtual-2)
caminhoPai = 'C:\\Users\\Usuario\\Desktop\\Área de testes'
for caminhoPasta in os.listdir(caminhoPai): #Logo farei uma função recursiva que diminua esse código, mas ainda tenho que estudá-las
caminhoFilho1 = caminhoPai+"\\"+caminhoPasta
for caminhoPasta2 in os.listdir(caminhoFilho1):
caminhoFilho2 = caminhoFilho1+"\\"+caminhoPasta2
for caminhoPasta3 in os.listdir(caminhoFilho2):
caminhoFilho3 = caminhoFilho2+"\\"+caminhoPasta3
for caminhoPasta4 in os.listdir(caminhoFilho3):
caminhoFilho4 = caminhoFilho3+"\\"+caminhoPasta4
arrayPastasVerificar = os.listdir(caminhoFilho4)
for pastaFinal in arrayPastasVerificar:
if verificarNome(pastaFinal):
caminhoPastaFinal = caminhoFilho4+"\\"+pastaFinal
os.remove(caminhoPastaFinal)

import os
import shutil
import datetime
month = datetime.date.today().replace(day=1)
oneMonthBefore= (month - datetime.timedelta(days=1)).replace(day=1)
twoMonthBefore= (oneMonthBefore - datetime.timedelta(days=1)).replace(day=1)
root = 'C:\\Users\\Admin\\Desktop\\Directorys'
for path, dirs, files in os.walk(root):
for dir in dirs[:]:
try:
dirDate = datetime.datetime.strptime(dir, '%Y%m')
except ValueError:
continue
if dirDate < twoMonthBefore:
dirs.remove(dir)
shutil.rmtree(os.path.join(path, dir))
