You can just iterate through with a for loop and replace each instance of a hyphen with a blank.
您可以使用 for 循环进行迭代，并将连字符的每个实例替换为空白。
hyphenlist = ['0-0-0', '1-10-20', '3-10-15', '2-30-20', '1-0-5', '1-10-6', '3-10-30', '3-10-4']
newlist = []
for x in hyphenlist:
newlist.append(x.replace('-', ''))
This code should give you a newlist without the hyphens.
这段代码应该给你一个没有连字符的新列表。

Or as a list comprehension:
或者作为列表理解：
>>>l=['0-0-0', '1-10-20', '3-10-15', '2-30-20', '1-0-5', '1-10-6', '3-10-30', '3-10-4']
>>>[i.replace('-','') for i in l]
['000', '11020', '31015', '23020', '105', '1106', '31030', '3104']
