Python – Union of Tuples
  • Last Updated : 30 Jan, 2020

Sometimes, while working with tuples, we can have a problem in which we need union of two records. This type of application can come in Data Science domain. Let’s discuss certain ways in which this problem can be solved.

Method #1 : Using set() + “+” operator 
This task can be performed using union functionality offered by + operator over sets. The conversion to set is done by set().




# Python3 code to demonstrate working of
# Union of Tuples
# Using set() + "+" operator
  
# initialize tuples
test_tup1 = (3, 4, 5, 6)
test_tup2 = (5, 7, 4, 10)
  
# printing original tuples
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))
  
# Union of Tuples
# Using set() + "+" operator
res = tuple(set(test_tup1 + test_tup2))
  
# printing result
print("The union elements from tuples are : " + str(res))
Output : 
The original tuple 1 : (3, 4, 5, 6)
The original tuple 2 : (5, 7, 4, 10)
The union elements from tuples are : (3, 4, 5, 6, 7, 10)

 
Method #2 : Using union() + set() 
This is method similar to above method, the difference is that instead of + operator, we use inbuilt function to perform the task of filtering dissimilar elements.
 




# Python3 code to demonstrate working of
# Union of Tuples
# Using union() + set()
  
# initialize tuples
test_tup1 = (3, 4, 5, 6)
test_tup2 = (5, 7, 4, 10)
  
# printing original tuples
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))
  
# Union of Tuples
# Using union() + set()
res = tuple(set(test_tup1).union(set(test_tup2)))
  
# printing result
print("The union elements from tuples are : " + str(res))
Output : 
The original tuple 1 : (3, 4, 5, 6)
The original tuple 2 : (5, 7, 4, 10)
The union elements from tuples are : (3, 4, 5, 6, 7, 10)
