用例子说明

fruit = ['pineapple','grape','pear']fruit[0:0] = ['Orange'] #在fruit集合中第一位插入字符串'Orange'print(fruit) #['Orange','pineapple','grape','pear']fruit[0] = 'Grapefruit' #将fruit集合的第一位元素替换为'Grapefruit'print(fruit) #['Grapefruit','pineapple','grape','pear']fruit[0:0] = 'Grapefruit' print(fruit) #['G','r','a','p','e','f','r','u','i','t','Grapefruit','pineapple','grape','pear']

以上这篇Python之列表的插入&替换修改方法就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
