Unit 4 - Lesson 7

40.1.1. Introduction to tuples

(c) Tuples can be used as keys in dictionaries.
(d) Elements of a tuple are enclosed in parenthesis.
(f) It is possible to create tuples which contain mutable objects, such as lists.

40.1.2. Write a Program to Convert a User given List into Tuple.

data = input("data: ")
list1 = data.split(",")
print("list:", list1)
#convert the above list to tuple
tuple1 = tuple(list1)
#print the tuple
print("tuple:",  tuple1 )

40.2.1. Understanding basic tuple operations

(c) The result of concatenation of two tuples when assigned to one of the tuple creates a new tuple.
(d) The result of repetition of a tuple when assigned to the same tuple will result in a new tuple.

40.2.2. Accessing the elements of a tuple

data = input("data: ")
list1 = data.split(",")
print("list:", list1)
#convert the list into tuple
mytuple = tuple(list1)
print("tuple:",mytuple)
#take the input fr index
index = int(input("index: "))
#write your code here to find the element at index
if index<len(mytuple) and -index<=len(mytuple):
	print("element:",mytuple[index])
else:
	print("enter valid index")

40.2.3. Understanding tuple assignment

(b) The output of the following code: ('ac',) * 2 is ('ac', 'ac').
(c) (1, 2, 3) > (1, 0, 3) is True.

40.2.4. Understanding Tuple Repetition and Concatenation

#write your code here
a = tuple(input("data1: ").split(","))
b = int(input("value: "))
print("tuple * ",b,"=",a*b)
a2 = tuple(input("data2: ").split(","))
print("concatenation:", a+a2)

40.2.5. Membership test in a Tuple

data = input("data: ")
list1 = data.split(",")
#convert the list to tuple
tuple1 = tuple(list1)
print("tuple:", tuple1)
#take an input element
input = input("value: ")
#write your logic to check for the condition
if input in tuple1:
	print(True)
else:
	print(False)

40.2.6. Deleting a tuple

mytup = ('a', 'b', 'c', 'd', [1, 2, 3])
print("mytup =", mytup)
print("del mytup[4][2]")

# delele the element 3 from the mytup
del mytup[-1][-1]
print("mytup =", mytup)
print("del mytup[4] will give TypeError")

40.2.7. Write a Program to Add an element into Tuple based on user given Value in Specific Index

data = input("data: ")
list1 = data.split(",")
#convert the list to tuple
tuple1 = tuple(list1)
#get input for index
index = int(input("index: "))
#write your logic here to insert the value
if index<len(tuple1) and -index<=len(tuple1):
	val = input("value: ")
	list1[index] = val
	tuple1 = tuple(list1)
	print("tuple:",tuple1)
else:
	print("enter valid index")

40.2.8. Write a program to remove an element from tuple based on user given Index

data = input("data: ")
list1 = data.split(",")
#convert the list to tuple
tuple1 = tuple(list1)
#print the tuple
print("tuple:",tuple1)
#get input for index
index = int(input("index: "))
#write your logic here to delete the value at given index
if index<len(tuple1) and -index<=len(tuple1):
	del list1[index]
	print("after removing:", tuple(list1))
else:
	print("enter valid index")

40.2.9. Write a Program to Compare Two given Tuples

data = input("data1: ")
list1 = data.split(",")
#convert the list1 to tuple
tuple1 = tuple(list1)
data1 = input("data2: ")
list2 = data1.split(",")
#convert the list2 to tuple
tuple2 = tuple(list2)
#write your logic here to compare them
if tuple1 == tuple2:
	print(True)
else:
	print(False)

40.2.10. Write a Program to Find the Tuple elements within a range of User given ranges

#write your code here
data = input("data: ").split(",")
s = int(input("start index: "))
e = int(input("end index: "))
if e<len(data) and -e<=len(data):
	print("tuple in given range:", tuple(data[s:e]))
else:
	print("enter valid index")
