How to add elements to a tuple in python? Tuples in Python are similar to lists but they cannot be changed. This makes them useful in certain situations. The immutability of tuples makes them ideal for certain tasks and scenarios.
You can add an element or multiple elements to a tuple by using many ways, for example, using the + operator, * unpacking. In this article, I will explain adding elements to a tuple by using all these methods with examples.
1. Quick Examples of Add Element to Tuple
If you are in a hurry, below are some quick examples of how to add elements to a tuple.
# Quick examples to add element to tuple
# Example 1: Add two tuples
tuple1 = (1, 3, 5)
tuple2 = (7, 8, 9)
tuple3 = tuple1 + tuple2
# Example 2: Add tuple using list.append()
# With one element
tuples = (2, 4, 6, 8)
list1 = list(tuples)
list1.append(12)
result = tuple(list1)
# Example 3: Adding a new tuple
# To an existing tuple
tuples = (3, 5, 7)
tuples1 = tuples + (9,)
# Example 4: Using tuple concatenation
tuples2 = (1,) + tuples
# Example 5: Add to a tuple with unpacking
tuples = (2, 4, 6, 8, 12)
tuples = (*tuples, 15)
# Example 6: Unpacking the elements
# Of an existing tuple
tuples = (2, 4, 6, 8, 12)
tuples = (0, *tuples)
# Example 9: Use reassignment (+=) operator
tuples = ('Spark', 'Python')
tuples += ('Pandas',)
2. Add Elements to Tuple in Python
You can add elements from one tuple to another in Python by using the + operator. When you concatenate two tuples, a new tuple is created that consists of all the elements from the original two tuples. For example, let’s create tuples tuple1 and tuple2, and then concatenated them using the + operator to create a new tuple tuple3.
# Concatenate two tuples
tuple1 = (1, 3, 5)
tuple2 = (7, 8, 9)
tuple3 = tuple1 + tuple2
print(tuple3)
# Output:
# (1, 3, 5, 7, 8, 9)
To add a tuple with a single element, you can use the + operator, just like with any other tuple. When concatenating a tuple with one element, the element needs to be in a tuple itself, otherwise, it will be interpreted as a separate value and not as part of the tuple.
# Adding a new tuple
# To an existing tuple
tuples = (3, 5, 7)
tuples1 = tuples + (9,)
print(tuples1)
# Output:
# (3, 5, 7, 9)
# Using tuple concatenation
tuples2 = (1,) + tuples
print(tuples2)
# Output:
# (1, 3, 5, 7)
3. Add Elements to Tuple using list.append()
Alternatively, you can convert the tuple to a list using the list() function, add an element to the list using the append() method, and then convert the list back to a tuple using the tuple() function.
# Concatenate tuple with one element
tuples = (2, 4, 6, 8)
# Convert tuple to list
list1 = list(tuples)
# Append element
list1.append(12)
# Convert list to tuple
result = tuple(list1)
print(result)
# Output:
# (2, 4, 6, 8, 12)
4. Add to a Tuple with Unpacking
Using unpacking technique when creating a new tuple in Python, you can unpack the elements of an existing tuple into a new tuple which ideally adds elements to tuple. For example, create tuple with elements 2, 4, 6, 8, and 12. Then, created a new tuple by unpacking the elements tuples into them and adding a new element 15 at the last.
The * operator is used to unpack the elements tuples into the new tuple. The result of the unpacking is a new tuple with the elements 2,4,6,8,12,15.
# Add to a tuple with unpacking
tuples = (2, 4, 6, 8, 12)
tuples = (*tuples, 15)
print(tuples)
# Output:
# (2, 4, 6, 8, 12, 15)
# Unpacking the elements
# Of an existing tuple
tuples = (2, 4, 6, 8, 12)
tuples = (0, *tuples)
print(tuples)
# Output:
# (0, 2, 4, 6, 8, 12)
5. Use Reassignment (+=) Operator
Similarly, you can also use the reassignment operator (+=) to add a new element to the same tuple.
# Use reassignment (+=) operator
tuples = ('Spark', 'Python')
tuples += ('Pandas',)
print(tuples)
# Output:
# ('Spark', 'Python', 'Pandas')
Conclusion
In this article, I have explained how to add elements to a tuple in python by using the + operator, * unpacking, append(), and reassignment (+=) operator with examples.
