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']
