Tuple Flashcards
Every topic from tuple and its functions
What is a tuple in Python?
A tuple is a sequence data type.
It is a heterogeneous collection of data (can contain different types of elements).
It is immutable, meaning it cannot be changed after creation.
Tuples are denoted by parentheses () and elements are separated by commas.
How do you create a tuple in Python?
With multiple elements: T = (8, 6, 7)
With a single element: T = (5,) (comma is necessary)
Without parentheses: T = 5, (comma is necessary)
Without a comma: T = (5) is not a tuple, it’s an integer.
String vs Tuple: T = (‘Hello’) is a string, not a tuple.
How does tuple indexing work in Python?
Tuples are indexed starting from 0.
Negative indexing starts from -1 (rightmost element).
Example: T = (5, 8, 6, 1, 9)
T[2] returns 6 (positive index).
T[-3] returns 6 (negative index).
T[6] raises an IndexError (out of range).
How do you concatenate two tuples?
T1 = (1, 2, 3)
T2 = (4, 5, 6)
T = T1 + T2 # Result: (1, 2, 3, 4, 5, 6)
How do you repeat a tuple?
T = (1, 2) * 3 # Result: (1, 2, 1, 2, 1, 2)
How do you check if an element is in a tuple?
Use the in and not in operators.
T = (5, “India”, 8, 6, 1)
5 in T # True
9 in T # False
9 not in T # True
How does slicing work in tuples?
Syntax: Object_name[start : stop : interval]
Defaults:
start: 0
stop: length of tuple (if interval is positive), -1 (if interval is negative)
interval: 1
T = (5, 8, 6, 1, 9)
T[1:4:1] # Result: (8, 6, 1)
T[1:5:2] # Result: (8, 1)
T[4:1:-1] # Result: (9, 1, 6)
What does the len() function do in tuples?
Returns the total number of elements in the tuple.
T = (8, 6, ‘Hello’, 9, 1)
len(T) # Result: 5
What does the tuple() function do?
Converts an object (e.g., string, list) into a tuple.
S = “Python”
T = tuple(S) # Result: (‘P’, ‘y’, ‘t’, ‘h’, ‘o’, ‘n’)
What does the count() function do in tuples?
Counts the number of occurrences of an element in the tuple.
T = (1, 2, 3, 2, 4, 2, 5)
T.count(2) # Result: 3
What does the index() function do in tuples?
Returns the index of the first occurrence of an element.
T = (1, 2, 3, 2, 4, 2, 5)
T.index(2) # Result: 1
What does the sorted() function do in tuples?
Returns a new list of sorted elements in ascending order (default).
Does not modify the original tuple.
T = (1, 2, 3, 2, 4, 2, 5)
sorted(T) # Result: [1, 2, 2, 2, 3, 4, 5]
sor
What does the min() function do in tuples?
Returns the smallest element in the tuple.
T = (5, 8, 3, 9, 6, 4)
min(T) # Result: 3
What does the max() function do in tuples?
Returns the largest element in the tuple.
T = (5, 8, 3, 9, 6, 4)
max(T) # Result: 9
What does the sum() function do in tuples?
Returns the sum of all elements in the tuple.
T = (5, 8, 3, 9, 6, 4)
sum(T) # Result: 35
What is a nested tuple?
A tuple that contains another tuple as an element.
T = (5, (8, 6, 4), 3, 9)
T[1] # Result: (8, 6, 4)
T[1][1] # Result: 6
Can a list be an element of a tuple?
Yes, a list can be an element of a tuple.
The list inside the tuple is mutable.
T = (5, [8, 6, 4], 3, 9)
T[1][2] = 7 # Result: (5, [8, 6, 7], 3, 9)
Write a program to find the maximum and minimum number in a tuple.
T = (5, 8, 9, 6, 2, 5)
print(“Tuple is:”, T)
print(“Minimum number:”, min(T))
print(“Maximum number:”, max(T))
Write a program to find the mean of numeric values in a tuple.
T = eval(input(“Enter a numeric tuple: “))
print(“Tuple is:”, T)
mean = sum(T) / len(T)
print(“Mean of the tuple:”, mean)
Write a program to find the index of a number in a tuple using linear search.
Write a program to find the index of a number in a tuple using linear search.
Write a program to count the frequency of all elements in a tuple.
T = (10, 20, 30, 20, 40, 30, 20, 50)
print(“Tuple is:”, T)
Uni = ()
for i in T:
if i not in Uni:
Uni = Uni + (i,)
for i in Uni:
print(i, “:”, T.count(i))
