[英]How to generate dynamically combinations of list in python
I want to generate combination dynamically in python, I have a var sessionperweeks
(between 2 and 6)我想在 python 中动态生成组合,我有一个 var
sessionperweeks
(在 2 到 6 之间)
if sessionperweeks==2
for i in range(0,7):
for j in range(i+1,7):
combins.append([i,j])
if sessionperweeks==3
for i in range(0,7):
for j in range(i+1,7):
for k in range(j+1,7):
combins.append([i,j,k])
and so on等等
Here you go, using combinations
from itertools
to pick sessions per week from 0-6:这里是 go,使用来自
itertools
的combinations
从 0-6 每周挑选会话:
from itertools import combinations
sessionsperweek = int(input("Enter sessions per week:"))
combins = list(combinations(range(7), sessionsperweek))
print("Your possible combinations are:")
print(combins)
Example run with 2 (since OP updated):使用 2 运行的示例(因为更新了 OP):
Enter sessions per week:2
Your possible combinations are:
[(0, 1), (0, 2), (0, 3), (0, 4), (0, 5), (0, 6), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6), (2, 3), (2, 4), (2, 5), (2, 6), (3, 4), (3, 5), (3, 6), (4, 5), (4, 6), (5, 6)]
Example run:示例运行:
Enter sessions per week:6
Your possible combinations are:
[(0, 1, 2, 3, 4, 5), (0, 1, 2, 3, 4, 6), (0, 1, 2, 3, 5, 6), (0, 1, 2, 4, 5, 6), (0, 1, 3, 4, 5, 6), (0, 2, 3, 4, 5, 6), (1, 2, 3, 4, 5, 6)]
