# Python – Sum of tuple elements

Sometimes, while programming, we have a problem in which we might need to perform summation among tuple elements. This is an essential utility as we come across summation operations many times and tuples are immutable and hence required to be dealt with. Letâ€™s discuss certain ways in which this task can be performed.

## Sum the elements of a Tuple in Python

There are several methods by which we can get the sum of elements of a tuple in Python. A few methods are given below:

• Using list() + sum() to find Python Sum of Tuple
• Python map() + sum() + list() to find sum of tuple
• Using for loop to find the sum of tuples in Python
• Python list comprehension to find the sum of tuple
• Sum of the tuple using a generator expression and the built-in sum() in Python
• Sum of tuple with Math in Python
• Sum of tuple with ZIP function in Python
• Python reduce() + operator.add() to find sum of tuple
• A sum of tuple with Numpy in Python

### Using list() + sum() to Find Python Sum of Tuple

In this example, we are defining function names as a summation that takes a tuple test_tup as input. After that, we are converting the tuple into a list and a for loop to traverse through the list and add the sum into a count variable.

## Python3

 `def` `summation(test_tup):` `    ``# Converting into list``    ``test ``=` `list``(test_tup)` `    ``# Initializing count``    ``count ``=` `0` `    ``# for loop``    ``for` `i ``in` `test:``        ``count ``+``=` `i``    ``return` `count`  `# Initializing test_tup``test_tup ``=` `(``5``, ``20``, ``3``, ``7``, ``6``, ``8``)``print``(summation(test_tup))`

Output :

```The original tuple is : (7, 8, 9, 1, 10, 7)
The summation of tuple elements are: 42```

### Find sum of Tuple using map() + sum() + list()

In this example, we have a tuple of lists. we are in the map function and which does sums of every list inside the tuple and appends the sum of every list to a new list then we are calling the sum function on the final list and assigning it to a res variable.

## Python3

 `# Python 3 code to demonstrate working of``# Tuple elements inversions``# Using map() + list() + sum()` `# initializing tup``test_tup ``=` `([``7``, ``8``], [``9``, ``1``], [``10``, ``7``])` `# printing original tuple``print``(``"The original tuple is : "` `+` `str``(test_tup))` `# Tuple elements inversions``# Using map() + list() + sum()``res ``=` `sum``(``list``(``map``(``sum``, ``list``(test_tup))))` `# printing result``print``(``"The summation of tuple elements are : "` `+` `str``(res))`

Output :

```The original tuple is : (7, 8, 9, 1, 10, 7)
The summation of tuple elements are: 42```

### Sum of tuples in Python using for Loop

In this example, we are using a for loop to traverse through the tuple and add the values to the res variable and print it.

## Python3

 `# Python3 code to demonstrate working of``# Tuple summation` `# Initializing tuple``test_tup ``=` `(``7``, ``8``, ``9``, ``1``, ``10``, ``7``)` `# Printing original tuple``print``(``"The original tuple is : "` `+` `str``(test_tup))` `res ``=` `0``for` `i ``in` `test_tup:``    ``res ``+``=` `i` `# Printing result``print``(``"The summation of tuple elements are : "` `+` `str``(res))`

Output :

```The original tuple is : (7, 8, 9, 1, 10, 7)
The summation of tuple elements are : 42```

### Python List Comprehension to find the Sum of Tuple

In this example, we use list comprehension to convert the tuple to a list and sum up the elements.

## Python3

 `def` `summation(test_tup):``    ``# Convert the tuple to a list using a list comprehension``    ``test ``=` `[x ``for` `x ``in` `test_tup]``    ` `    ``# Find the sum of the elements in the list using the built-in sum() function``    ``return` `sum``(test)` `# Test the function with a tuple of integers``test_tup ``=` `(``5``, ``20``, ``3``, ``7``, ``6``, ``8``)``print``(summation(test_tup))`

Output :

`49`

### Sum of the Tuple using a Generator Expression and the Built-In sum() in Python

The summation2 function takes a tuple as input and calculates the sum of its elements. It checks that the tuple is not empty or it has any other datatype then it raises an error. Then we create an iterable to iterate in the tuple. Send the iterable to the sum function which returns the total_sum.

## Python3

 `def` `summation2(test_tup):``    ``# Check if the input is empty or contains non-integer elements``    ``if` `len``(test_tup) ``=``=` `0``:``        ``raise` `ValueError(``"Input tuple is empty"``)``    ``if` `not` `all``(``isinstance``(x, ``int``) ``for` `x ``in` `test_tup):``        ``raise` `TypeError(``"Input tuple must contain only integers"``)``    ` `    ``# Use a generator expression to convert``    ``# the tuple to an iterable``    ``iterable ``=` `(x ``for` `x ``in` `test_tup)``    ` `    ``# Find the sum of the elements in the iterable``    ``# using the built-in sum() function``    ``total_sum ``=` `sum``(iterable)``    ` `    ``return` `total_sum``test_tup ``=` `(``5``, ``20``, ``3``, ``7``, ``6``, ``8``)``print``(summation2(test_tup))`

Output :

`49`

### Sum of tuple with Math in Python

In this example, first, we have Imported the math library. Then we Initialized the tuple test_tup with the given elements. Then we created a variable res and assign it the value returned by the math.fsum() function, which calculates the sum of all the elements in the tuple.

## Python3

 `import` `math` `# initializing tuple``test_tup ``=` `(``7``, ``8``, ``9``, ``1``, ``10``, ``7``)` `# calculating sum of tuple elements using math.fsum()``res ``=` `math.fsum(test_tup)` `# printing result``print``(``"The summation of tuple elements are : "` `+` `str``(res))`

Output :

`The summation of tuple elements are : 42.0`

### Sum of tuple with ZIP function in Python

In this example, we are using the zip function to combine the three tuples and we are using the map(sum, combined) which calculates the sum of elements using sum.

## Python3

 `tuple1 ``=` `(``1``, ``2``, ``3``)``tuple2 ``=` `(``4``, ``5``, ``6``)``tuple3 ``=` `(``7``, ``8``, ``9``)` `combined ``=` `zip``(tuple1, tuple2, tuple3)``result ``=` `tuple``(``map``(``sum``, combined))``print``(result) `

Output :

`(12, 15, 18)`

### Python reduce() + operator.add() to find sum of Tuple

The reduce() function can be used to iterate through the tuple and the operator.add() function can be used for the summation of elements.

## Python3

 `import` `operator``from` `functools ``import` `reduce` `def` `summation(test_tup):``# Using reduce() + operator.add()``  ``return` `reduce``(operator.add, test_tup)` `#initializing test_tup``test_tup ``=` `(``5``, ``20``, ``3``, ``7``, ``6``, ``8``)``print``(summation(test_tup))``#This code is contributed by Edula Vinay Kumar Reddy`

Output :

`49`

### Sum of tuple with Numpy in Python

To find the sum of the elements in a tuple, we could convert the tuple to a Numpy array and then use the numpy.sum() function.

## Python3

 `# Python3 code to demonstrate working of``# Tuple summation using numpy``import` `numpy as np` `# Initializing tuple``test_tup ``=` `(``7``, ``8``, ``9``, ``1``, ``10``, ``7``)` `# Converting tuple to numpy array``test_array ``=` `np.array(test_tup)` `# Printing original tuple``print``(``"The original tuple is : "` `+` `str``(test_tup))` `# Finding sum of array elements``res ``=` `np.``sum``(test_array)` `# Printing result``print``(``"The summation of tuple elements are : "` `+` `str``(res))`

Output :

```The original tuple is : (7, 8, 9, 1, 10, 7)
The summation of tuple elements are : 42```
