os.remove is not working

[solomon]

I tried to split a pdf file (e.g. called xyz.pdf) which is roughly 20 pages and I succeeded too. After I did the splitting, I try to delete the original file which is "xyz.pdf" by using os.remove(path). But the file is not getting removed and at the same time, it is getting deleted when I do it from separate .py file. Below is the code:

import os, datetime

date = datetime.datetime.now().strftime('%d%b')
root_path = "E:\\Downloads\\01 Newspapers\\Telugu PDF"


folders = [
#            'Andhrabhoomi',
            'Andhrajyothy',
            'Andhraprabha',
            'Prajasakti',
            'Sakshi'
            ]

for folder in folders :
    pdf_path = os.path.join (root_path, folder)
    file01 = date + " " + folder + " Pg.pdf"
    file02 = date + " " + folder + " Vwd City Pg.pdf"
        
    os.remove(pdf_path+'\\'+ file01)
    os.remove(pdf_path+'\\'+ file02)
    
    file03 = date + " " + folder + " Guntur City Pg.pdf"
    src_fi = pdf_path + "\\Guntur\\" + file03
    dst_fi = pdf_path + "\\Guntur\\" + file03[:-18] + " _Guntur.pdf"
    
    os.rename (src_fi, dst_fi)

You write the file is not deleted. Does the program show an error message?
