Python程序将带有分隔符的字符串列表转换为元组列表

给定一个包含带有特定分隔符的字符串的列表。任务是删除分隔符并将字符串转换为元组列表。

例子：

Input : test_list = [“1-2”, “3-4-8-9”], K = “-” 
Output : [(1, 2), (3, 4, 8, 9)] 
Explanation : After splitting, 1-2 => (1, 2).
 

Input : test_list = [“1*2”, “3*4*8*9”], K = “*” 
Output : [(1, 2), (3, 4, 8, 9)] 
Explanation : After splitting, 1*2 => (1, 2). 

方法 #1：使用列表理解 + split()

在这种情况下，首先，使用 split() 以 K 作为参数分割每个字符串，然后使用列表理解将其扩展到所有字符串。

# Python3 code to demonstrate working of
# Convert K delim Strings to Integer Tuple List
# Using list comprehension + split()
  
# initializing list
test_list = ["1-2", "3-4-8-9", "4-10-4"]
  
# printing original list
print("The original list is : " + str(test_list))
  
# initializing K
K = "-"
  
# conversion using split and list comprehension
# int() is used for conversion
res = [tuple(int(ele) for ele in sub.split(K)) for sub in test_list]
  
# printing result
print("The converted tuple list : " + str(res))

输出

The original list is : ['1-2', '3-4-8-9', '4-10-4']
The converted tuple list : [(1, 2), (3, 4, 8, 9), (4, 10, 4)]

方法 #2：使用 map() + split() + 列表理解

这里使用map()完成积分扩展逻辑的扩展任务，然后使用列表推导来执行构建列表的任务。

# initializing list
test_list = ["1-2", "3-4-8-9", "4-10-4"]
  
# printing original list
print("The original list is : " + str(test_list))
  
# initializing K
K = "-"
  
# extension logic using map()
# int() is used for conversion
res = [tuple(map(int, sub.split(K))) for sub in test_list]
  
# printing result
print("The converted tuple list : " + str(res))

输出

The original list is : ['1-2', '3-4-8-9', '4-10-4']
The converted tuple list : [(1, 2), (3, 4, 8, 9), (4, 10, 4)]
