Description :

The provided Python script defines a function named ‘sumOfNumbers’ that calculates the sum of all numeric elements within a given list or tuple. It ensures the validity of the input data by checking if it’s a list or tuple and whether the elements are integers or floats. If the input is valid, it computes the sum and returns it. If the input is invalid (e.g., non-numeric elements or non-list/tuple input), appropriate error messages are returned. The script also includes examples demonstrating the usage of the’ sumOfNumbers’ function with different types of input arrays.

The content of the provided Python script includes:

1. *Function Definition*:
– The script defines a function named sumOfNumbers(array) that takes one parameter array, representing a list or tuple.
– It checks if the input array is a list or tuple using isinstance.
– It initializes a variable res to zero to store the sum of numeric elements.

2. *Sum Calculation*:
– The function iterates over each element in the array.
– For each element, it checks if it’s an integer or float using isinstance.
– If the element is numeric, it adds it to the running sum stored in res.

3. *Result Return*:
– If the sum res is non-zero, it returns the sum.
– If no valid numeric elements are found in the array, it returns the message “Provide valid data”.

4. *Error Handling*:
– If the input is neither a list nor a tuple, it returns the message “Provide either list or tuple with integers”.

5. *Example Usage*:
– The script provides examples demonstrating the usage of the sumOfNumbers function with different types of input arrays.
– It includes tests with valid lists, valid tuples, invalid lists with non-numeric elements, and invalid input types.

This script is useful for calculating the sum of numeric elements in a list or tuple while ensuring data integrity and providing informative error messages for invalid input.

 

Explanation:

 

The provided code defines a function named sumOfNumbers which calculates the sum of all numeric elements within a given list or tuple.

Here’s a breakdown of the code:

 *Function Definition*:
– The function sumOfNumbers(array) takes one parameter array, representing either a list or a tuple.

 *Type Checking*:
– The function checks if the input array is either a list or a tuple using the isinstance function.

*Sum Calculation*:
– It initializes a variable res to zero to store the sum of numeric elements.
– It iterates over each element in the array and checks if it’s an integer or a float using isinstance.
– If the element is numeric, it adds it to the running sum stored in res.

*Result Return*:
– If the sum res is non-zero, it returns the sum.
– If no valid numeric elements are found in the array, it returns the message “Provide valid data”.

 *Error Handling*:
– If the input is neither a list nor a tuple, it returns the message “Provide either list or tuple with integers”.

 *Example Usage*:
– It demonstrates examples of using the sumOfNumbers function with different types of input arrays.

 

Code:

def sumOfNumbers(array):
    if isinstance(array, list) or isinstance(array, tuple):
        res = 0
        for i in array:
            if isinstance(i, (int, float)):
                res += i
        return res if res else "Provide valid data"
    else:
        return "Provide either list or tuple with integers"

tuple_array = (1, 2, 3, 5)
print(sumOfNumbers([1, 5, 3]))
print(sumOfNumbers(tuple_array))
print(sumOfNumbers(["s"]))
print(sumOfNumbers("string"))

Output:

9
11
Provide valid data
Provide either list or tuple with integers
