list()与tuple()接受可迭代对象作为参数,并通过浅拷贝数据来创建一个新的列表或元组。 如果不考虑range()函数,python中没有特定用于列表的内建函数。 range()函数接受一个数值作为输入,输出一个符合标准的列表。 列表类型内建函数列表: --- list.append(obj)---向列表中添加一个对象obj list.count(obj)---...
Instead of a single element, let us try to insert another list into the existing list using the insert() method. In this example, we are first creating a list [123, 'xyz', 'zara', 'abc']. Then, this method is called on this list by passing another list and an index value as ...
