What is a tuple?
A tuple is a sequence data type in Python that is used to store a collection of items. It is immutable, meaning once created, its elements cannot be changed. Tuples are defined using parentheses () and elements are separated by commas. Example: T = (1, 2, 3)
Write the difference between Lists and Tuples?
Lists:
Lists are mutable, meaning their elements can be modified after creation.
Lists are defined using square brackets [].
Example: L = [1, 2, 3].
Tuples:
Tuples are immutable, meaning their elements cannot be modified after creation.
Tuples are defined using parentheses ().
Example: T = (1, 2, 3).
If x is (2,4,5)
(a) What is the difference between (if any) x * 3 and (x, x, x) ?
(b)Is x * 5 is equivalent to x + x + x + x + x?
(c) What is the meaning of x[1:1]?
(a) What is the difference between x * 3 and (x, x, x)?
x * 3 results in (2, 4, 5, 2, 4, 5, 2, 4, 5) (repetition of elements).
(x, x, x) results in ((2, 4, 5), (2, 4, 5), (2, 4, 5)) (a tuple of tuples).
(b) Is x * 5 equivalent to x + x + x + x + x?
Yes, x * 5 is equivalent to x + x + x + x + x. Both will result in (2, 4, 5, 2, 4, 5, 2, 4, 5, 2, 4, 5, 2, 4, 5).
(c) What is the meaning of x[1:1]?
x[1:1] returns an empty tuple () because the start and stop indices are the same, so no elements are included in the slice.
What is the difference between a= (50) and a = (50,) ?
a = (50) is not a tuple; it is an integer because the comma is missing.
a = (50,) is a tuple with a single element 50. The comma makes it a tuple.
Find the output generated by following code fragment:
i) Code 1
P1=(“Marathon”, “ Rally”)
P1[0]=”Olympic”
P1 = (“Marathon”, “ Rally”)
P1[0] = “Olympic”
Output: This will raise a TypeError because tuples are immutable, and you cannot change their elements.
(x, y, z) = (5, 10, 15)
(w, x, y, z) = (2, 4, 6)
Output: This will raise a ValueError because the number of variables on the left side (4) does not match the number of values on the right side (3).
- Predict the output.
a = (5, (10, (30, (40,))))
print(len(a))
print(a[1][0])
print(10 in a)
b = (100,(200,(300,),400),500)
print(len(b))
print(len(b[1]))
print(b[0]+500)
a = (5, (10, (30, (40,))))
print(len(a)) # Output: 2 (because ‘a’ has 2 elements: 5 and a nested tuple)
print(a[1][0]) # Output: 10 (first element of the nested tuple)
print(10 in a) # Output: False (10 is not directly in ‘a’, it’s inside a nested tuple)
b = (100, (200, (300), 400), 500)
print(len(b)) # Output: 3 (because ‘b’ has 3 elements)
print(len(b[1])) # Output: 3 (the nested tuple has 3 elements: 200, 300, 400)
print(b[0] + 500) # Output: 600 (100 + 500)
What will be following code produce?
T5=(300,)*5
T5[0] = 250
print(T5)
T5 = (300,) * 5
T5[0] = 250
print(T5)
This will raise a TypeError because tuples are immutable, and you cannot change their elements.
What will be the output of the following code snippet?
Tup1 = ((5,10),) * 10
print(len(Tup1[2:5]))
Output: **3 **(because Tup1[2:5] slices the tuple from index 2 to 4, which includes 3 elements).
Write a program to display the number of odd and even values in a tuple DataTup created by user-defined values.
DataTup = eval(input(“Enter a tuple: “))
even_count = 0
odd_count = 0
for num in DataTup:
if num % 2 == 0:
even_count += 1
else:
odd_count += 1
print(“Number of even values:”, even_count)
print(“Number of odd values:”, odd_count)
Write a program to find and display the average value of a given tuple MyTuple.
MyTuple = eval(input(“Enter a tuple: “))
average = sum(MyTuple) / len(MyTuple)
print(“Average value of the tuple:”, average)
