带颠倒和列表的:

>>> list1 = [1,2,3]
>>> reversed_list = list(reversed(list1))
>>> reversed_list
>>> [3, 2, 1]

一行代码中用户输入值的反向:

for i in input()[::-1]: print(i,end='')

要反转相同的列表，请使用:

array.reverse()

将反向列表赋值到其他列表使用:

newArray = array[::-1] 

如果你想在其他变量中存储反转列表的元素，那么你可以使用revArray = array[::-1]或revArray = list(reversed(array))。

但是第一个变体稍微快一点:

z = range(1000000)
startTimeTic = time.time()
y = z[::-1]
print("Time: %s s" % (time.time() - startTimeTic))

f = range(1000000)
startTimeTic = time.time()
g = list(reversed(f))
print("Time: %s s" % (time.time() - startTimeTic))

输出:

Time: 0.00489711761475 s
Time: 0.00609302520752 s

内置功能最少，假设是面试设置

array = [1, 2, 3, 4, 5, 6,7, 8]
inverse = [] #create container for inverse array
length = len(array)  #to iterate later, returns 8 
counter = length - 1  #because the 8th element is on position 7 (as python starts from 0)

for i in range(length): 
   inverse.append(array[counter])
   counter -= 1
print(inverse)

>>> L = [1, 2, 3, 4]
>>> L = [L[-i] for i in range(1, len(L) + 1)]
>>> L
[4, 3, 2, 1]
