python - re.sub 多次替换两个特定字符之间的子字符串

Question

s给定如下字符串but，我想ball多次删除子字符串：

s = 'I like sport, but I don\'t like football; I like sport, but I don\'t like basketball'
re.sub('but.*ball', '', s, flags=re.MULTILINE)

出去：

'I like sport, '

我怎么能得到这样的预期结果：

'I like sport, I like sport'

尝试添加一个问号：

>>> re.sub('but.*?ball|[,;]', '', s, flags=re.MULTILINE).strip()
'I like sport  I like sport'
