Misread the question and picked option 5 - Costumes[1][2][0:1]
Would that return both "Blue" and "Orange"?
I'm not a regular SQL Server user anymore and not familiar with tuples...

Hi Arno,
today's Qotd is about accessing values of Tuples in Python.

print Costumes[1][2][0:1]; returns ('Blue',)
print Costumes[1][2][1:2]; returns ('Orange',)
print Costumes[1][2][0:2]; returns ('Blue', 'Orange')
print Costumes[0][1][0:6]; returns Batman

I tried below example from w3schools.com and getting an error.

Example:
thistuple = ("apple", "banana", "cherry")
thistuple[1] = "blackcurrant"
# The values will remain the same:
print(thistuple)

Result:
>>> thistuple = ("apple", "banana", "cherry")
>>> thistuple[1] = "blackcurrant"
Traceback (most recent call last):
File "<pyshell#33>", line 1, in <module>
thistuple[1] = "blackcurrant"
TypeError: 'tuple' object does not support item assignment
>>>

Any Idea.

ThanksSaurabh.D

Any Idea.

Tuples are immutable which means you cannot update or change the values of tuple elements.
You are able to take portions of existing tuples to create new tuples as the following example demonstrates:

#!/usr/bin/python

thistuple = ("apple", "banana", "cherry");
print thistuple;
fruits = ("apricot", "strawberry", "pear");
print fruits;
all_tuples = thistuple + fruits;
print all_tuples;

Result
$python main.py
('apple', 'banana', 'cherry')
('apricot', 'strawberry', 'pear')
('apple', 'banana', 'cherry', 'apricot', 'strawberry', 'pear')
