Python: Append items from inerrable to the end of the array
Python: Array Exercise-7 with Solution
Write a Python program to append items from inerrable to the end of the array.
Pictorial Presentation:
Sample Solution:
Python Code :
from array import *
array_num = array('i', [1, 3, 5, 7, 9])
print("Original array: "+str(array_num))
array_num.extend(array_num)
print("Extended array: "+str(array_num))
Sample Output:
Original array: array('i', [1, 3, 5, 7, 9]) Extended array: array('i', [1, 3, 5, 7, 9, 1, 3, 5, 7, 9])

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")
