Python Exercise: Compute element-wise sum of given tuples
Python tuple: Exercise-31 with Solution
Write a Python program to compute element-wise sum of given tuples.
Sample Solution:-
Python Code:
x = (1,2,3,4)
y = (3,5,2,1)
z = (2,2,3,1)
print("Original lists:")
print(x)
print(y)
print(z)
print("\nElement-wise sum of the said tuples:")
result = tuple(map(sum, zip(x, y, z)))
print(result)
Sample Output:
Original lists: (1, 2, 3, 4) (3, 5, 2, 1) (2, 2, 3, 1) Element-wise sum of the said tuples: (6, 9, 8, 6)

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")
