Getting Permission error when renaming python

Question

I want to rename files and subdirectories with my python script.
simply replacing "." with spaces.

sample dir tree:

.\fsdf.trsd.nf.g
.\beautifyer.py
.\lsWithSdir.py
.\fsdf.trsd.nf.g\fe.gre.asd
.\fsdf.trsd.nf.g\fa.tr.b.d.txt
.\fsdf.trsd.nf.g\fe.gre.asd\new.path
.\fsdf.trsd.nf.g\fe.gre.asd\New.Text.Document.txt

import os
from os.path import isdir

# prompt user for path
dirPath = input("enter path of dir where the files are\n")

# subs = input("do you want to include renaming for subdirectories? (y/n)\n")

# change to path
os.chdir(dirPath)


# replace spaces
def replace_spaces(file_name):
    new_name = file_name.replace(".", " ")
    return new_name

def checkType(filePath, file):
    if os.path.isdir(file):
        new_name = replace_spaces(file)
        os.rename(filePath, os.path.join(filePath , new_name))
    else:
        file_name, file_ext = os.path.splitext(file)
        new_name = replace_spaces(file_name)
        os.rename(filePath, os.path.join(filePath , new_name + file_ext))



def get_items(dirPath):
    for path, subdirs, files in os.walk(dirPath):
        for name in subdirs:
            file_path = os.path.join(path)
            # doStuff(file_path, name)
            print(file_path + " | " + name)
            checkType(file_path, name)
        for name in files:
            file_path = os.path.join(path)
            checkType(file_path, name)


get_items(dirPath) 

Error:

You were sending wrong filepath to checkType function see the modified code as below:

import os
from os.path import isdir

# prompt user for path
dirPath = input("enter path of dir where the files are\n")

# replace spaces
def replace_spaces(file_name):
    new_name = file_name.replace(".", " ")
    return new_name

def checkType(filePath, file):
    if os.path.isdir(filePath):
        new_name = replace_spaces(file)
        os.rename(filePath, os.path.join(os.path.dirname(filePath) , new_name))
    else:
        file_name, file_ext = os.path.splitext(file)
        new_name = replace_spaces(file_name)
        os.rename(filePath, os.path.join(os.path.dirname( filePath) , new_name + file_ext))



def get_items(dirPath):
    for path, subdirs, files in os.walk(dirPath):
        for name in subdirs:
            file_path = os.path.join(path,name)
            # doStuff(file_path, name)
            print(file_path + " | " + name)
            checkType(file_path, name)
        for name in files:
            file_path = os.path.join(path, name)
            checkType(file_path, name)

get_items(dirPath)
