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")
