构造等位数元组的Python程序

给定元素列表，将元组列表划分为相似的数字元组对。

Input : test_list = [5654, 223, 982143, 34, 1021] 
Output : [(56, 54), (2, 23), (982, 143), (3, 4), (10, 21)] 
Explanation : Element in tuples equidistributed.

Input : test_list = [5654, 223, 1021] 
Output : [(56, 54), (2, 23), (10, 21)] 
Explanation : Element in tuples equidistributed. 
 

方法 #1：使用循环 + 切片 + str()

在这里，我们通过获取mid-idx然后从mid切片来执行除法任务，使用str()将最初的整数拆分为一个字符串。

Python3

# Python3 code to demonstrate working of 
# Construct Equidigit tuples
# Using loop + slicing str()
  
# initializing list
test_list = [5654, 223, 982143, 34, 1021]
  
# printing original list
print("The original list is : " + str(test_list))
  
res = []
for sub in test_list:
      
    # getting mid element
    mid_idx = len(str(sub)) // 2
      
    # slicing Equidigits
    el1 = str(sub)[:mid_idx]
    el2 = str(sub)[mid_idx:]
      
    res.append((int(el1), int(el2)))
  
# printing result 
print("Equidigit tuples List : " + str(res))

输出：

The original list is : [5654, 223, 982143, 34, 1021]
Equidigit tuples List : [(56, 54), (2, 23), (982, 143), (3, 4), (10, 21)]
