Python | How to Concatenate tuples to nested tuples

Last Updated : 21 Nov, 2019

Sometimes, while working with tuples, we can have a problem in which we need to convert individual records into a nested collection yet remaining as separate element. Usual addition of tuples, generally adds the contents and hence flattens the resultant container, this is usually undesired. Let’s discuss certain ways in which this problem is solved.

Method #1 : Using + operator + ", " operator during initialization
In this method, we perform the usual addition of tuple elements, but while initializing tuples, we add a comma after the tuple so that they don’t get flattened while addition.

# Python3 code to demonstrate working of
# Concatenating tuples to nested tuples
# using + operator + ", " operator during initialization
  
# initialize tuples
test_tup1 = (3, 4),
test_tup2 = (5, 6),
  
# printing original tuples
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))
  
# Concatenating tuples to nested tuples
# using + operator + ", " operator during initialization
res = test_tup1 + test_tup2
  
# printing result
print("Tuples after Concatenating : " + str(res))

Output :

The original tuple 1 : ((3, 4), )
The original tuple 2 : ((5, 6), )
Tuples after Concatenating : ((3, 4), (5, 6))

Method #2 : Using “, ” operator during concatenation
This task can be performed by applying “, ” operator during concatenation as well. It can perform the safe concatenation.

# Python3 code to demonstrate working of
# Concatenating tuples to nested tuples
# Using ", " operator during concatenation
  
# initialize tuples
test_tup1 = (3, 4)
test_tup2 = (5, 6)
  
# printing original tuples
print("The original tuple 1 : " + str(test_tup1))
print("The original tuple 2 : " + str(test_tup2))
  
# Concatenating tuples to nested tuples
# Using ", " operator during concatenation
res = ((test_tup1, ) + (test_tup2, ))
  
# printing result
print("Tuples after Concatenating : " + str(res))

Output :

The original tuple 1 : ((3, 4), )
The original tuple 2 : ((5, 6), )
Tuples after Concatenating : ((3, 4), (5, 6))
