list.index(obj,i=0,j=len(list))---返回list[k]==obj的k值,并且k的范围在 i<=k<J;否则引发ValueError异常。 list.insert(index,obj)---在索引量为index的位置插入对象obj。 list.pop(index=-1)---删除并返回指定位置的对象,默认是最后一个对象 list.remove(obj)---从列表中删除对象obj list.revers...
Python also allows slicing of the lists. You can access a part of complete list by using index range. There are various ways through which this can be done. Here are some examples : If it is required to access a sub-list from index 1 to index 3 then it can be done in following wa...
To remove the multiple elements/items from the python list by index, you can use any above-mentioned methods, however, I will use the del keyword to explain. In order to use this you need a list of element indexes you wanted to remove and use it with for loop to remove iteratively. H...
enumerate()与zip():前者是输出列表的index和元素值;后者等长的两个列表对应为的元素组合成一个元组,生成一个元组列表。sum()和reduce():对数字列表进行求和。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...
