Python tuple program to sort a tuple by the maximum value of a tuple

In this python tuple program, we will sort a tuple by the maximum value of a tuple.

Steps to solve the program

Take a list of tuples as input.
Use sorted() to sort the tuple and pass the lambda function to sort the tuple by the maximum value to the key inside the sorted().
Print the output.

				
					l = [ (1, 5, 7), (3, 4, 2), (4, 9, 0) ]
print("Original list of tuples: ",l)
l1 = sorted(l,key = lambda x: max(x),reverse=True)
print("After sorting: ",l1)

Output :

				
					Original list of tuples:  [(1, 5, 7), (3, 4, 2), (4, 9, 0)]
After sorting:  [(4, 9, 0), (1, 5, 7), (3, 4, 2)]

remove nested elements from a tuple.

sort a list of tuples by the minimum value of a tuple.

Python tuple program to remove nested elements from a tuple

In this python tuple program, we will remove nested elements from a tuple.

Steps to solve the program

Take a tuple as input and create an empty list.
Use a for loop to iterate over values from the tuple.
If the type of the value is not a tuple then add those values to the empty list.
Now convert the new list to a tuple using tuple().
Print the output.

				
					tup = ('s','q','a',('t','o','o','l','s'),'i','s','b','e','s','t')
print("Original tuple: ",tup)
l = []
for char in tup:
    if type(char) != tuple:
        l.append(char)
new = tuple(l)
print("New tuple: ",new)

Output :

				
					Original tuple:  ('s', 'q', 'a', ('t', 'o', 'o', 'l', 's'), 'i', 's', 'b', 'e', 's', 't')
New tuple:  ('s', 'q', 'a', 'i', 's', 'b', 'e', 's', 't')

return an empty set if no tuples are symmetrical.

sym = {(a, b) for a, b in temp if a < b}

sym = {(a, b) for a, b in temp if a < b}
print("Tuples that are symmetric: ",sym)

Output :

				
					Original list of tuples:  [('a', 'b'), ('d', 'e'), ('b', 'a')]
Tuples that are symmetric:  {('a', 'b')}

return an empty set if no tuples are symmetrical.

Program to convert a list of lists to a tuple of tuples

In this python tuple program, we will convert a list of lists to a tuple of tuples.

Steps to solve the program

Take a list of lists as input and create an empty list.
Use a for loop to iterate over lists in the list.
Add the list to the empty list using append() after converting it to a tuple using tuple().
Now convert the new list to a tuple using tuple().
Print the output.

				
					l = [['sqatools'],['is'],['best']]
print("List of lists: ",l)
l1 = []
for lists in l:
    l1.append(tuple(lists))
tup = tuple(l1)
print("Tuple of tuples: ",tup)

Output :

				
					List of lists:  [['sqatools'], ['is'], ['best']]
Tuple of tuples:  (('sqatools',), ('is',), ('best',))

extract tuples that are symmetrical with others from a list of tuples.

Convert a tuple into a list by adding the string after every element of the tuple

In this python tuple program, we will convert a tuple into a list by adding the string after every element of the tuple.

Steps to solve the program

Take a tuple and a string as input.
Create an empty list.
Use a for loop to iterate over elements in the tuple.
Add the element and the string to the empty list using append().
Repeat the process for all elements.
Print the output.

				
					a = (1,2,3,4)
print("Tuple: ",a)
b= 'sqatools'
print("String: ",b)
l = []
for ele in a:
    l.append(ele)
    l.append(b)

Output :

				
					Tuple:  (1, 2, 3, 4)
String:  sqatools
New list:  [1, 'sqatools', 2, 'sqatools', 3, 'sqatools', 4, 'sqatools']

In this python tuple program, we will flatten a list of tuples into a string.

Steps to solve the program

Take a list of tuples as input and create an empty string.

Multiply ith element from each tuple from a list of tuples

In this python tuple program, we will multiply ith element from each tuple from a list of tuples.

Take a list of tuples as input.
Create a variable i and product set their value equal to 1.
Use a for loop to iterate over tuples in the list.
Use a nested for loop to iterate over elements in the tuples.
Check if the index of the element in the tuple is equal to i using index().
If the index is equal then multiply the product variable with that element of the tuple.
