用于从元组列表中查找所有元素都可被 K 整除的元组的Python程序

给定一个元组列表。任务是提取所有元素可被 K 整除的所有元组。

Input : test_list = [(6, 24, 12), (60, 12, 6), (12, 18, 21)], K = 6 
Output : [(6, 24, 12), (60, 12, 6)] 
Explanation : Both tuples have all elements multiple of 6.

Input : test_list = [(6, 24, 12), (60, 10, 5), (12, 18, 21)], K = 5 
Output : [(60, 10, 5)] 
Explanation : Multiple of 5 tuples extracted. 

方法 #1：使用列表理解 + all()

在此，我们使用 all() 测试所有元素是否为 K 倍数以用于过滤目的，列表推导用于所有元组的迭代。

Python3

# Python3 code to demonstrate working of
# K Multiple Elements Tuples
# Using list comprehension + all()
  
# initializing list
test_list = [(6, 24, 12), (7, 9, 6), (12, 18, 21)]
  
# printing original list
print("The original list is : " + str(test_list))
  
# initializing K
K = 6
  
# all() used to filter elements
res = [sub for sub in test_list if all(ele % K == 0 for ele in sub)]
  
# printing result
print("K Multiple elements tuples : " + str(res))

输出

The original list is : [(6, 24, 12), (7, 9, 6), (12, 18, 21)]
K Multiple elements tuples : [(6, 24, 12)]

方法 #2：使用 filter() + lambda + all()

在此，我们使用 filter() + lambda 和 all() 提供的逻辑执行过滤任务，如上述方法。

Python3

# Python3 code to demonstrate working of
# K Multiple Elements Tuples
# Using filter() + lambda + all()
  
# initializing list
test_list = [(6, 24, 12), (7, 9, 6), (12, 18, 21)]
  
# printing original list
print("The original list is : " + str(test_list))
  
# initializing K
K = 6
  
# filter() + lambda for filter operation
res = list(filter(lambda sub: all(ele % K == 0 for ele in sub), test_list))
  
# printing result
print("K Multiple elements tuples : " + str(res))

输出

The original list is : [(6, 24, 12), (7, 9, 6), (12, 18, 21)]
K Multiple elements tuples : [(6, 24, 12)]
