Python Exercise: Add an item in a tuple

Python tuple: Exercise-5 with Solution

Write a Python program to add an item in a tuple.

Sample Solution:-

Python Code:

#create a tuple
tuplex = (4, 6, 2, 8, 3, 1) 
print(tuplex)
#tuples are immutable, so you can not add new elements
#using merge of tuples with the + operator you can add an element and it will create a new tuple
tuplex = tuplex + (9,)
print(tuplex)
#adding items in a specific index
tuplex = tuplex[:5] + (15, 20, 25) + tuplex[:5]
print(tuplex)
#converting the tuple to list
listx = list(tuplex) 
#use different ways to add items in list
listx.append(30)
tuplex = tuple(listx)
print(tuplex)

Sample Output:

(4, 6, 2, 8, 3, 1)                                                                                            
(4, 6, 2, 8, 3, 1, 9)                                                                                         
(4, 6, 2, 8, 3, 15, 20, 25, 4, 6, 2, 8, 3)                                                                    
(4, 6, 2, 8, 3, 15, 20, 25, 4, 6, 2, 8, 3, 30)

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")
