Python Exercise: Check if a specified element presents in a tuple of tuples
Python tuple: Exercise-30 with Solution
Write a Python program to check if a specified element presents in a tuple of tuples.
Sample Solution:
Python Code:
def check_in_tuples(colors, c):
result = any(c in tu for tu in colors)
return result
colors = (
('Red', 'White', 'Blue'),
('Green', 'Pink', 'Purple'),
('Orange', 'Yellow', 'Lime'),
)
print("Original list:")
print(colors)
c1 = 'White'
print("\nCheck if",c1,"presenet in said tuple of tuples!")
print(check_in_tuples(colors, c1))
c1 = 'White'
print("\nCheck if",c1,"presenet in said tuple of tuples!")
print(check_in_tuples(colors, c1))
c1 = 'Olive'
print("\nCheck if",c1,"presenet in said tuple of tuples!")
print(check_in_tuples(colors, c1))
Sample Output:
Original list: (('Red', 'White', 'Blue'), ('Green', 'Pink', 'Purple'), ('Orange', 'Yellow', 'Lime')) Check if White presenet in said tuple of tuples! True Check if White presenet in said tuple of tuples! True Check if Olive presenet in said tuple of tuples! False

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")
