Python Calculate Sum of Array Elements

Document 对象参考手册Python3 Examples

Define an integer array and calculate the sum of its elements.

Implementation requirements:

Input: arr[] = {1, 2, 3}

Output: 6

Calculation: 1 + 2 + 3 = 6

Example

# Define a function, arr is the array, n is the array length, can be used as a spare parameter, not used here
def _sum(arr,n):
     
    # Use the built-in sum function to calculate
    return(sum(arr))
 
# Call the function
arr=[]
# Array elements
arr = [12, 3, 4, 15]
 
# Calculate the length of the array elements
n = len(arr)
 
ans = _sum(arr,n)
 
# Output the result
print ('The sum of array elements is',ans)

The above example outputs the following:

数组元素之和为 34
