Python kiểm tra xem đầu vào có trống không

Sử dụng len[] là phương pháp chung nhất để kiểm tra chuỗi có độ dài bằng không. Mặc dù nó bỏ qua thực tế là một chuỗi chỉ có khoảng trắng cũng thực tế được coi là chuỗi rỗng ngay cả khi nó khác không

Phương pháp #2. sử dụng không

toán tử not cũng có thể thực hiện tác vụ tương tự như len[] và kiểm tra chuỗi có độ dài 0, nhưng giống như trên, nó coi chuỗi chỉ có khoảng trắng cũng không trống, điều này thực tế không đúng.

Phương pháp #3. Sử dụng not + str. dải[]

Vấn đề về chuỗi trống + độ dài bằng 0 có thể được loại bỏ bằng cách sử dụng dải[], dải[] trả về giá trị true nếu nó gặp khoảng trắng, do đó việc kiểm tra nó có thể giải quyết vấn đề kiểm tra chuỗi hoàn toàn trống.

Hoạt động theo cách tương tự như phương pháp trên và kiểm tra khoảng trắng trong chuỗi. Phương pháp này hiệu quả hơn bởi vì, dải [] yêu cầu thực hiện thao tác dải cũng cần tải tính toán, nếu không. không gian có số lượng tốt
