Tôi có thể sử dụng cái gì thay vì phạm vi trong Python?

range[] và xrange[] là hai hàm có thể được sử dụng để lặp lại một số lần nhất định trong vòng lặp for trong Python. Trong Python 3, không có xrange, nhưng hàm phạm vi hoạt động giống như xrange trong Python 2. Nếu bạn muốn viết mã sẽ chạy trên cả Python 2 và Python 3, bạn nên sử dụng phạm vi []

• phạm vi [] - Điều này trả về một đối tượng phạm vi [một loại có thể lặp lại]
• xrange[] – Hàm này trả về đối tượng trình tạo có thể được sử dụng để hiển thị các số chỉ bằng cách lặp. Phạm vi cụ thể duy nhất được hiển thị theo yêu cầu và do đó được gọi là "đánh giá lười biếng"

Cả hai đều được thực hiện theo những cách khác nhau và có những đặc điểm khác nhau liên quan đến chúng. Các điểm so sánh là.  

• Loại trả lại
• Kỉ niệm
• Hoạt động sử dụng
• Tốc độ, vận tốc

Loại trả lại

range[] trả về – đối tượng phạm vi.
xrange[] trả về – đối tượng xrange[].

Kỉ niệm

Biến lưu trữ phạm vi được tạo bởi phạm vi[] chiếm nhiều bộ nhớ hơn so với biến lưu trữ phạm vi sử dụng xrange[]. Lý do cơ bản cho điều này là kiểu trả về của phạm vi[] là danh sách và xrange[] là đối tượng xrange[].

Hoạt động sử dụng

Vì phạm vi [] trả về danh sách, nên tất cả các hoạt động có thể được áp dụng trên danh sách đều có thể được sử dụng trên đó. Mặt khác, khi xrange[] trả về đối tượng xrange, các thao tác liên quan đến danh sách không thể được áp dụng trên chúng, do đó sẽ gặp bất lợi
