Hướng dẫn add number in list python - thêm số vào danh sách python

Một cách đơn giản là sử dụng hoán vị iter_tools

# If you are given a list

numList = [1,2,3,4,5,6,7]

# and you are asked to find the number of three sums that add to a particular number

target = 10
# How you could come up with the answer?

from itertools import permutations

good_permutations = []

for p in permutations(numList, 3):
    if sum(p) == target:
        good_permutations.append(p)

print(good_permutations)

Kết quả là:

[(1, 2, 7), (1, 3, 6), (1, 4, 5), (1, 5, 4), (1, 6, 3), (1, 7, 2), (2, 1, 7), (2, 3, 
5), (2, 5, 3), (2, 7, 1), (3, 1, 6), (3, 2, 5), (3, 5, 2), (3, 6, 1), (4, 1, 5), (4, 
5, 1), (5, 1, 4), (5, 2, 3), (5, 3, 2), (5, 4, 1), (6, 1, 3), (6, 3, 1), (7, 1, 2), 
(7, 2, 1)]

Lưu ý rằng vấn đề thứ tự - có nghĩa là 1, 2, 7 cũng được hiển thị là 2, 1, 7 và 7, 1, 2. Bạn có thể giảm điều này bằng cách sử dụng một tập hợp.

    Chúng ta có thể thêm số nguyên vào danh sách trong Python không?

    Một trong những cách phổ biến nhất để thêm số nguyên vào danh sách, chứ đừng nói đến bất kỳ loại dữ liệu nào khác là sử dụng phương thức append ().Điều này chỉ đơn giản sẽ thêm một số nguyên duy nhất vào cuối danh sách.use the append() method. This will simply add a single integer to the very end of the list.

    Làm thế nào để tôi nối vào một danh sách?

    append () thêm một danh sách bên trong danh sách.Danh sách là đối tượng và khi bạn sử dụng.append () Để thêm một danh sách khác vào danh sách, các mục mới sẽ được thêm vào dưới dạng một đối tượng (mục). adds a list inside of a list. Lists are objects, and when you use . append() to add another list into a list, the new items will be added as a single object (item).
