Hướng dẫn how do i create a pair of two lists in python? - làm cách nào để tạo một cặp hai danh sách trong python?

Sử dụng chức năng zip, cùng với việc giải nén Tuple:

for x, y in zip(xs, ys):
    print x, y

Trong trường hợp của bạn, tùy thuộc vào những gì bạn cần

with filein as f:
    reader=csv.reader(f)
    for x, y in reader:
        print x, y

with filein as f:
    reader=csv.reader(f)
    for x, y in reader:
        print x, y

with filein as f:
    reader=csv.reader(f)
    for x, y in reader:
        print x, y

with filein as f:
    reader=csv.reader(f)
    for x, y in reader:
        print x, y

Mà không có sự lặp lại

Để loại bỏ tất cả các yếu tố lặp đi lặp lại từ danh sách ban đầu, chúng tôi sử dụng hàm set () trên cả hai danh sách, riêng lẻ. Sau đó, chúng tôi thêm chúng bằng cách sử dụng toán tử++và truyền dưới dạng danh sách mới. & NBSP;

Liên minh của một danh sách có nghĩa là, chúng ta phải lấy tất cả các yếu tố từ Danh sách A và Danh sách B (có thể có nhiều hơn hai danh sách) và đưa chúng vào trong một danh sách mới. Có nhiều đơn đặt hàng khác nhau trong đó chúng tôi có thể kết hợp các danh sách. Ví dụ, chúng ta có thể duy trì sự lặp lại và đặt hàng hoặc xóa các phần tử lặp lại trong danh sách cuối cùng, v.v. & NBSP;
