Python tuple program to order tuples by external list

In this python tuple program, we will order tuples by external list.

Steps to solve the program

Take a list of tuples and a list by which we have to order tuples as input.
Create a dictionary of a list of tuples.
It will set words in the tuples as keys and numbers as their values.
Use a for loop to iterate over words in the list by which we have to order the tuples.
Now add the word and its value in the dictionary to another list using list comprehension i.e. loop inside the list.
Print the output.

				
					list1 = [('very',8),('i',6),('am',5),('happy',0)]
list2 = ['i','am','very','happy']
print("List of tuple: ",list1)
print("List: ",list2)
d = dict(list1)
result = [(key, d[key]) for key in list2]
print("Output list: ",result)

Output :

				
					List of tuple:  [('very', 8), ('i', 6), ('am', 5), ('happy', 0)]
List:  ['i', 'am', 'very', 'happy']
Output list:  [('i', 6), ('am', 5), ('very', 8), ('happy', 0)]

tup2 = ('t','o','o','l')
print(f"Original tuple: {tup1} {tup2}")
result = tup1+tup2
print("Combined tuple: ",result)

Output :

				
					Original tuple: ('s', 'q', 'a') ('t', 'o', 'o', 'l')
Combined tuple:  ('s', 'q', 'a', 't', 'o', 'o', 'l')

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

Python tuple program to sort a list if tuples by the minimum value of a tuple

In this python tuple program, we will sort a list if tuples by the minimum 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 minimum 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: min(x))
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)]

print("Original list of tuples: ",l)
l1 = sorted(l,key = lambda x: max(x),reverse=True)
print("After sorting: ",l1)

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.

print("Original tuple: ",tup)
l = []
