TypeError:'list'object is not callable 产生原因 callable() 是python 的内置函数,用来检查对象是否可被调用 变量list和函数list重名,所以函数在使用list函数时,发现list是一个定义好的列表,而列表是不能把被调用的,因此抛出一个类型错误 6. Python 实现两个列表里元素对应相乘 ...
1. List list is an ordered contiguous memory space containing several elements 2. When the list adds or deletes elements, the list object automatically expands or shrinks its memory 3. When inserting or deleting an element at a non-tail position, the list index of the element behind the pos...
The order in which you specify the elements when you define a list is an innate characteristic of that list and is maintained for that list’s lifetime. (You will see a Python data type that is not ordered in the next tutorial on dictionaries.)...

1、list can hold arbitrary objects and can expand dynamically as new items are added. A list is an ordered set of items. 2、A tuple is an immutable list. A tuple can not be changed in any way once it is created. 3、A set is an unordered “bag” of unique values. A single set ...
A list in Python is an ordered collection of items that can be of different data types. Lists are mutable, meaning you can change their content without changing their identity. Here’s a quick example of how to create a list: MY LATEST VIDEOS ...
