英文:
Python: Given a number return tuple from 0, a number given
问题
以下是要翻译的内容：
给定：num=4
期望：(0,1), (0,2), (0,3), (0,4), (1,2), (1,3), (1,4), (2,3), (2,4), (3,4)（以元组形式）
英文:
Hi I would like to knoq how I can achieve this in python.
given: num=4
expect: (0,1), (0,2), (0,3), (0,4), (1,2), (1,3), (1,4), (2,3), (2,4), (3,4) (in tuple)
答案1
得分: 1
使用嵌套循环：
>>> num = 4>>> for i in range(num):... for j in range(i+1, num+1):... print((i, j))...(0, 1)(0, 2)(0, 3)(0, 4)(1, 2)(1, 3)(1, 4)(2, 3)(2, 4)(3, 4)
使用 itertools：
>>> import itertools>>> print(*itertools.combinations(range(num+1), 2), sep="\n")(0, 1)(0, 2)(0, 3)(0, 4)(1, 2)(1, 3)(1, 4)(2, 3)(2, 4)(3, 4)
英文:
Using nested loops:
>>> num = 4>>> for i in range(num):... for j in range(i+1, num+1):... print((i, j))...(0, 1)(0, 2)(0, 3)(0, 4)(1, 2)(1, 3)(1, 4)(2, 3)(2, 4)(3, 4)
Using itertools:
>>> import itertools>>> print(*itertools.combinations(range(num+1), 2), sep="\n")(0, 1)(0, 2)(0, 3)(0, 4)(1, 2)(1, 3)(1, 4)(2, 3)(2, 4)(3, 4)
