萌新想问一下，为啥老是报错提示无法解释为整数
class Nstr(str):def __sub__(self,other):
self = list(self)
other = list(other)
for i in other:
self.pop(i)
print(str(self))
a = Nstr('i love you and she')
b = Nstr('and she')
a - b for i in other: # other列表：['a', 'n', 'd', ' ', 's', 'h', 'e']，i就是一个个字符，
self.pop(i)# 列表pop得写元素的index，但i是字符串，所以报错。 本帖最后由 jackz007 于 2021-11-23 17:59 编辑
class Nstr(str):
def __sub__(self,other):
self = list(self . split())
other = list(other . split())
for i in other:
self . remove(i)
print('' . join(s + ' ' for s in self))
a = Nstr('i love you and she')
b = Nstr('and she')
