017、a.sort(reverse=True) 与 a.reverse()

 

a.sort(reverse=True) :   reverse 为关键字参数, 先排序再反转 ;

a.reverse()  :reverse() 为方法,把a反转 ;

 

a = [2, 4, 1, 3]
a.sort(reverse=True)
print(a)

b = [2, 4, 1, 3]
print(b[::-1])

c = [2, 4, 1, 3]
c.reverse()
print(c)

执行结果如下:

D:\SkyWorkSpace\WorkSpace\Pytest\Temp\day09\venv\Scripts\python.exe D:/SkyWorkSpace/WorkSpace/Pytest/Temp/day09/test_01/test_01.py
[4, 3, 2, 1]
[3, 1, 4, 2]
[3, 1, 4, 2]

Process finished with exit code 0
