Your job in this exercise is to write a list comprehension that produces a list of the squares of the numbers ranging from 0 to 9. Createlistcomprehension: squares squares = [i**2foriinrange(0,10)] nested list comprehensions [[output expression]foriterator variableiniterable] writing a list...
Insert an item at a given position. The first argument is the index of the element before which to insert, soa.insert(0,x)inserts at the front of the list, anda.insert(len(a),x)is equivalent toa.append(x). 在指定的位置增加一个元素,第一个参数是插入元素的索引,也就是在该元素之前插入...
