Given the lists li_num1 = [4,5,2,7] and li_num2 = [3,6], please merge these two lists into one list and sort the elements in the merged list in descending order
- Use the extend() method to add all the elements of another list at the end of the list at once
- Use the sort() method to arrange the elements in a list in a specific order
Sample code:
#python第5章编程第一题
li_num1 = [4,5,2,7] #创建li_num1和li_num2列表
li_num2 = [3,6]
li_num1.extend(li_num2) #用extend()函数将li_num2加入li_num1的末尾
li_num1.sort(reverse=True) #用sort()函数将列表中的元素按降序排列
#参数reverse用于控制列表元素排列方式，参数可取值True(降序)或Flase(升序)
print(li_num1)operation result:
