如何从字符串列表中删除连字符

Question

['0-0-0', '1-10-20', '3-10-15', '2-30-20', '1-0-5', '1-10-6', '3-10-30', '3-10-4']

如何删除数字之间的所有连字符？

Answer 1

您可以使用for循环遍历，并将连字符的每个实例替换为空格。

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('-', ''))

这段代码应该会给出一个不带连字符的新列表。

Answer 2

或者作为一种列表理解：

>>>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']
