Python Exercise: Remove an item from a tuple

Python tuple: Exercise-12 with Solution

Write a Python program to remove an item from a tuple.

Sample Solution:-

Python Code:

#create a tuple
tuplex = "w", 3, "r", "s", "o", "u", "r", "c", "e"
print(tuplex)
#tuples are immutable, so you can not remove elements
#using merge of tuples with the + operator you can remove an item and it will create a new tuple
tuplex = tuplex[:2] + tuplex[3:]
print(tuplex)
#converting the tuple to list
listx = list(tuplex) 
#use different ways to remove an item of the list
listx.remove("c") 
#converting the tuple to list
tuplex = tuple(listx)
print(tuplex)

Sample Output:

('w', 3, 'r', 's', 'o', 'u', 'r', 'c', 'e')                                                                   
('w', 3, 's', 'o', 'u', 'r', 'c', 'e')                                                                        
('w', 3, 's', 'o', 'u', 'r', 'e')

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")
