Arkadaşlar merhaba.
Bir siteden resimleri bilgisayara indirmek için için pythonla yazılmış bir yazılım kullanıyorum. Bazı sayfaları indiremiyorum. Klasör oluştururken [WinError 123] Dosya adı, dizin adı veya birim etiketi sözdizimi hatalı: böyle bir hata alıyorum.

yazılımın amacı aşağıdakı linkde her sayfada yer alan resimi bilgisaya indirmke.
http://web2.anl.az:81/read/page.php?bibid=vtls000006523

Not: amazımız eski kiril alfabesi eile yazılan ve unutulmaya yüz tutmuş kitapları yeniden canladırmak.

Yazılımın tamamı şu linkte var. https://drive.google.com/drive/folders/1KcFI3-q562jZF6ZEjqFgWA-JmE3TUykp?usp=sharing

functions dosyasının içeriği aşağıdaki gibidir.

This function returns three parameters we need to iterate through URLs of a single book:
1. base_url, which is same everywhere throughout the website,
2. bibib, which is the book id, hence same throughout the book, and
3. page_count, which will be used to construct a while loop (we need to know when to stop).
It also returns book_title, which we will use to name the folder and the PDF file.
