e_weight不满足断言

[unccx]

Describe the bug
dhg\structure\hypergraphs\hypergraph.py 的 add_hyperedges() 函数

// 判断e_weight 类型
        if e_weight is None:
            e_weight = [1.0] * len(e_list)
        elif type(e_weight) in (int, float):
            e_weight = [e_weight] // 这里错误 应该是 [e_weight] * len(e_list) 否则过不了下面的assert
        elif type(e_weight) is list:
            pass
        else:
            raise TypeError(f"The type of e_weight should be float or list, but got {type(e_weight)}")
        assert len(e_list) == len(e_weight), "The number of hyperedges and the number of weights are not equal."

To Reproduce
执行下面这段代码

from dhg import Hypergraph
hg = Hypergraph(4, [[0, 1, 2], [1, 2, 3]], e_weight=0.8)

显示

Traceback (most recent call last):
  File "D:\test.py", line 3, in <module>
    hg = Hypergraph(4, [[0, 1, 2], [1, 2, 3]], e_weight=0.8)
         ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  File "C:\Users\xxx\miniforge3\envs\task_hg\Lib\site-packages\dhg\structure\hypergraphs\hypergraph.py", line 48, in __init__
    self.add_hyperedges(e_list, e_weight, merge_op=merge_op)
  File "C:\Users\xxx\miniforge3\envs\task_hg\Lib\site-packages\dhg\structure\hypergraphs\hypergraph.py", line 345, in add_hyperedges
    assert len(e_list) == len(e_weight), "The number of hyperedges and the number of weights are not equal."
AssertionError: The number of hyperedges and the number of weights are not equal.

Expected behavior
e_weight 应该被正确设置为 [e_weight] * len(e_list)
