删除元素-remove()-discard()-pop()-clear() 1-remove() remove()用于删除一个set中的元素,这个值在set中必须存在,如果不存在的话,会引发KeyError错误. 2-discard() discard()用于删除一个set中的元素,这个值不必一定存在,不存在的情况下删除也不会触发错误. 3-pop() set提供了一个pop()方法,这个函数随机返回一个元素值,然后把这个值删除,如果set为空,调用这个函数会返回Key错误. 4-clear()…

1-remove()方法 根据值删除元素.  remove()方法传入一个列表中的值,它将从被调用的列表中删除. 如果该值在列表中出现多次,只有第一次出现的值会被删除. 如果要删除的值可能在列表中出现多次,就需要使用循环来判断是否删除了所有这样的值 试图删除列表中不存在的值,将导致 ValueError 错误. 2-del语句 del 语句将根据元素索引删除列表中的值,表中被删除值后面的所有值,都将向前移动一个下标. del 的常见错误   如果不确定该使用del 语句还是pop() 方法, 下…
