كنت أقضي ساعات في تنظيف البيانات يدويًا، لكن بعد هذه الدورة صرت أتمتم معالجة القيم المفقودة والمكررة بالبايثون. الجزء الخاص باستخدام الذكاء الاصطناعي للتحقق من صحة البيانات كان مفيدًا جدًا وعمليًا.

डेटा साफ करने में मेरा आधा दिन निकल जाता था, पर अब पायथन और AI से ये काम स्वचालित हो गया है। मिसिंग वैल्यू भरना और डुप्लिकेट हटाने वाला पाइपलाइन बनाना सबसे उपयोगी रहा, बिल्कुल रोज़ के काम के लायक।

Good practical intro to automating data cleaning, though the validation chapter felt a little rushed.
