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objlist.count(obj)---返回一个对...
Finding the index of an item in a list: In this tutorial, we will learn how to find the index of a given item in a Python list. Learn with the help of examples.
>>> myList[-1] 'sun' So we see that index -1 was translated into index ‘4’ and corresponding value was produced in output. If you are new to Python, you should start by writing aPython hello world program, and understandingPython variables and strings. ...
