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.

Syntax:
sum[iterable, start] iterable : iterable can be anything list , tuples or dictionaries , but most importantly it should be numbers. start : this start is added to the sum of numbers in the iterable. If start is not given in the syntax , it is assumed to be 0.
Bàn luận
sum[a] a is the list , it adds up all the numbers in the list a and takes start to be 0, so returning only the sum of the numbers in the list. sum[a, start] this returns the sum of the list + start

04sum[iterable, start] iterable : iterable can be anything list , tuples or dictionaries , but most importantly it should be numbers. start : this start is added to the sum of numbers in the iterable. If start is not given in the syntax , it is assumed to be 0.99
sum[a] a is the list , it adds up all the numbers in the list a and takes start to be 0, so returning only the sum of the numbers in the list. sum[a, start] this returns the sum of the list + start00
