Program to convert a list of tuples in a dictionary

In this python tuple program, we will convert a list of tuples in a dictionary.

Steps to solve the program

Take a list of tuples as input and create an empty dictionary.
Use for loop to iterate over each tuple in the list.
Use D.setdefault(a, []).append(b) it will set the first value in the tuple as the key and create an empty list to store its values.
a is the key and b is the value, D is the name of the dictionary.
If there is a tuple in the list whose key has been previously used then it will not create a new key-value pair instead it will add the value of the tuple to the existing list of key-value pair.
Print the output.

				
					l =  [('s',2),('q',1),('a',1),('s',3),('q',2),('a',4)]
print("List of tuples: ",l)
D = {}
for a, b in l:
    D.setdefault(a, []).append(b)

print("Dictionary: ",D)

Output :

				
					List of tuples:  [('s', 2), ('q', 1), ('a', 1), ('s', 3), ('q', 2), ('a', 4)]
Dictionary:  {'s': [2, 3], 'q': [1, 2], 'a': [1, 4]}

program to reverse a tuple.

Python tuple program to reverse a tuple

In this python tuple program, we will reverse a tuple.

Steps to solve the program

Take a tuple as input.
FIrst reverse the given tuple by using reversed() and then convert it to a tuple using tuple().
Print the output.

				
					tup = (4,6,8,3,1)
print("Original tuple: ",tup)
tup1 = tuple(reversed(tup))
print("Reversed tuple: ",tup1)

Output :

				
					Original tuple:  (4, 6, 8, 3, 1)
Reversed tuple:  (1, 3, 8, 6, 4)

convert a tuple into a dictionary.

Python tuple program to convert a tuple into a dictionary

In this python tuple program, we will convert a tuple into a dictionary.

Steps to solve the program

Take tuples inside a tuple as input.
Convert the tuple into a dictionary using dict().
Print the output.

				
					tup = ((5,'s'),(6,'l'))
print("Tuple: ",tup)
D = dict(tup)
print("Dictionary: ",D)

Output :

				
					Tuple:  ((5, 's'), (6, 'l'))
Dictionary:  {5: 's', 6: 'l'}

find the length of a tuple.

Python tuple program to find the length of a tuple

In this python tuple program, we will find the length of a tuple.

Steps to solve the program

Take a tuple as input.
Find the length of a tuple using len().
Print the output.

				
					tup = ('v','i','r','a','t')
print("Original tuple: ",tup)
print("Length of the tuple: ",len(tup))

Output :

				
					Original tuple:  ('v', 'i', 'r', 'a', 't')
Length of the tuple:  5

find an index of an element in a tuple.

convert a tuple into a dictionary.

Find an index of an element in a tuple

In this python tuple program, we will find an index of an element in a tuple.

Steps to solve the program

Create a tuple.
Find the index of an element in a tuple using index().
Print the output.

				
					tup = ('s','q','a','t','o','o','l','s')
print("Index of a: ",tup.index('a'))

Output :

				
					Index of a:  2

program to slice a tuple.

find the length of a tuple.

Python tuple program to slice a tuple

In this python tuple program, we will slice a tuple.

Steps to solve the program

Create a tuple.
Slice the given tuple using tuple_name[start_index:end_index].
Print the output.

				
					tup = (5,7,3,4,9,0,2)
print("Original tuple: ",tup)
print(tup[:3])
print(tup[2:5])

Output :

				
					Original tuple:  (5, 7, 3, 4, 9, 0, 2)
(5, 7, 3)
(3, 4, 9)

remove an item from a tuple.

find an index of an element in a tuple.

Python tuple program to remove an item from a tuple

In this python tuple program, we will remove an item from a tuple.

Steps to solve the program

Create a tuple.
Now convert that tuple to a list using list().
Remove the element from the list.
Again convert the list to a tuple using tuple().
Print the output.

				
					tup = ('p','y','t','h','o','n')
print("Original tuple: ",tup)
l = list(tup)
l.remove('h')
tup = tuple(l)
print("After removing an element: ",tup)

Output :

				
					Original tuple:  ('p', 'y', 't', 'h', 'o', 'n')
After removing an element:  ('p', 'y', 't', 'o', 'n')

convert a list into a tuple and multiply each element by 2.

program to slice a tuple.

Convert a list into a tuple and multiply each element

In this pythin tuple program, we will convert a list into a tuple and multiply each element.

Steps to solve the program

Create a list and an empty list.
Use for loop to iterate over elements in the list.
Multiply each element by 2 and add it to the empty list.
Now convert the new list to a tuple using tuple().
Print the output.

				
					list1 = [12,65,34,77]
list2 = []
for ele in list1:
    a = 2*ele
    list2.append(a)
    
tup = tuple(list2)
print("Origianl list: ",list1)
print("After multiplyting by 2: ",tup)

Output :

				
					Origianl list:  [12, 65, 34, 77]
After multiplyting by 2:  (24, 130, 68, 154)

remove an item from a tuple.

Python tuple program to multiply adjacent elements of a tuple

In this python tuple program, we will multiply adjacent elements of a tuple.

Steps to solve the program

Create a tuple and an empty list.
Create a tuple having adjacent elements as a tuple inside of a tuple using zip(tup,tup[1:]).
Use for loop to iterate over this tuple.
Now get the product of the adjacent element and add it to the empty list.
Convert the list back to the tuple using tuple().
Print the output.

				
					tup =  (1,2,3,4)
list1 = []
for a,b in zip(tup,tup[1:]):
    c = a*b
    list1.append(c)
tup = tuple(list1)
print("Multiplying adjacent elements: ",tup)

Output :

				
					Multiplying adjacent elements:  (2, 6, 12)
