编写一个 Python 程序,以逆序打印列表项。在 Python 中,我们可以使用带有负值的列表切片来反转列表项,或者使用列表反转方法。
a = [4, 7, 9, 11, 22, 44, 59]
print('Printing the List Items in Rererse')
print(a[::-1])
a.reverse()
print('\nPrinting the List Items in Rererse')
print(a)
在这个 Python 程序中,我们使用 for 循环从最后到第一次迭代列表项,以逆序打印列表项。
a = [10, 20, 30, 40, 50, 60]
for i in range(len(a) - 1, -1, -1):
print(a[i], end = ' ')
60 50 40 30 20 10
这个 Python 示例允许使用 for 循环输入列表项并以相反的顺序打印它们。
list1 = []
Number = int(input("Total Number of List Items to enter = "))
for i in range(1, Number + 1):
item = int(input("Please enter the %d Value = " %i))
list1.append(item)
for i in range(len(list1) - 1, -1, -1):
print(list1[i], end = ' ')
Total Number of List Items to enter = 7
Please enter the 1 Value = 9
Please enter the 2 Value = 11
Please enter the 3 Value = 22
Please enter the 4 Value = 14
Please enter the 5 Value = 67
Please enter the 6 Value = 89
Please enter the 7 Value = 123
123 89 67 14 22 11 9
Python 程序,使用 while 循环以相反的顺序打印列表项。
list1 = []
Number = int(input("Total Number of List Items to enter = "))
i = 1
while i <= Number:
item = int(input("Please enter the %d Value = " %i))
list1.append(item)
i = i + 1
print('Printing the List Items in Rererse')
i = len(list1) - 1
while i >= 0:
print(list1[i], end = ' ')
i = i - 1
Total Number of List Items to enter = 8
Please enter the 1 Value = 23
Please enter the 2 Value = 33
Please enter the 3 Value = 43
Please enter the 4 Value = 53
Please enter the 5 Value = 63
Please enter the 6 Value = 73
Please enter the 7 Value = 83
Please enter the 8 Value = 93
Printing the List Items in Rererse
