一个可迭代对象是不能独立进行迭代的,Python中,迭代是通过for ... in来完成的。凡是可迭代对象都可以直接用for… in…循环访问,这个语句其实做了两件事:第一件事是调用__iter__()获得一个可迭代器,第二件事是循环调用__next__()。 常见的可迭代对象包括:a) 集合数据类型,如list、tuple、dict、set、str...

a.sort(reverse = True) a #默认是升序,reverse = False是默认时候的状态 1. 2. 3. 4. list.sort()对列表元素进行排序操作 range()函数只处理第一个到最后一个数,但是不包括最后一个数。 5、while语句 while-loop只要一个布尔表达式是True,while-loop就会一直执行它下面的代码块直到为假。

在python中经常会遇到这样的一个代码: fruits=['apple','pear','peach']forfruitinfruits:print(fruit) list是一个有序的列表。我们可以根据顺序来for循环遍历整个list。使用string和tuple的时候也可以这样子for loop 遍历。这是非常符合代码直觉的,因为遍历的都是有序的对象。然而我们使用字典的时候,无序的对象我...
