Đôi khi, khi làm việc với Machine Learning, chúng ta có thể gặp các chuỗi rỗng và chúng ta muốn chuyển đổi thành Không có để thống nhất dữ liệu. Điều này và nhiều tiện ích khác có thể yêu cầu giải pháp cho vấn đề này. Hãy thảo luận về một số cách mà vấn đề này có thể được giải quyết
Phương pháp #1. Sử dụng lambda
Tác vụ này có thể được thực hiện bằng hàm lambda. Trong phần này, chúng tôi kiểm tra chuỗi cho Không có hoặc chuỗi trống bằng cách sử dụng toán tử hoặc và thay thế chuỗi trống bằng Không có.

Phương pháp #2. Sử dụng
The original list is : ['Geeks', '', 'CS', '', ''] The list after conversion of Empty Strings : ['Geeks', None, 'CS', None, None]37
Chỉ đơn giản là hàm str có thể được sử dụng để thực hiện tác vụ cụ thể này bởi vì, Không có giá trị nào cũng đánh giá thành giá trị “Sai” và do đó sẽ không được chọn và thay vào đó, một chuỗi được chuyển đổi thành sai sẽ đánh giá thành trống .
