python实现将一个数组逆序输出的方法

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="") 

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) 

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)
