Python: Compute the sum of elements of a given array of integers
Python map: Exercise-11 with Solution
Write a Python program to compute the sum of elements of a given array of integers, use map() function.
Sample Solution:
Python Code :
from array import array
def array_sum(nums_arr):
sum_n = 0
for n in nums_arr:
sum_n += n
return sum_n
nums = array('i', [1, 2, 3, 4, 5, -15])
print("Original array:",nums)
nums_arr = list(map(int, nums))
result = array_sum(nums_arr)
print("Sum of all elements of the said array:")
print(result)
Sample Output:
Original array: array('i', [1, 2, 3, 4, 5, -15]) Sum of all elements of the said array: 0

Python: Tips of the Day
Find current directory and file's directory:
To get the full path to the directory a Python file is contained in, write this in that file:
import os dir_path = os.path.dirname(os.path.realpath(__file__))
(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)
To get the current working directory use
import os cwd = os.getcwd()
Documentation references for the modules, constants and functions used above:
- The os and os.path modules.
- The __file__ constant
- os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
- os.path.dirname(path) (returns "the directory name of pathname path")
- os.getcwd() (returns "a string representing the current working directory")
- os.chdir(path) ("change the current working directory to path")
