How to output an array in reverse order in python

Method 1: (Recommended learning: Python video tutorial)

Use a for loop to traverse from the maximum value of the array , each time a value is printed, the maximum value of the array is decremented by one, and finally the array is output in reverse order.

def printTheReverseArray(self):
 list_1 = [1, 2, 3, 4, 5, 6, 7]
 length = len(list_1)
 for i in range(0, length):
  print(length - i,end="")
Copy after login

Method 2: Head insertion method

def printTheReverseArray(self):
 '头插法'
 list_1 = [1, 2, 3, 4, 5, 6, 7]
 list_2 = [list_1[0]]#
 for i in range(1, len(list_1)):
  list_2.insert(0, list_1[i])
 print(list_2)
Copy after login

Method 3:

Array swapping before and after

def printTheReverseArray(self):
 list_1 = [9, 6, 5, 4, 1]
 N = len(list_1)
 for i in range(int(len(list_1) / 2)):
  list_1[i], list_1[N - i - 1] = list_1[N - i - 1], list_1[i]
 print(list_1)
Copy after login
