Answer:
Explanation:
1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).
2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.
3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.
4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.

Answer:
Coding builds critical thinking. Critical thinking involves approaching a problem situation analytically and breaking it down into separate components! It also involves being mentally flexible and a rather easy way to express yourself. Every situation is unique in coding and you can always have a unique way to approach the problem to solve it.
Coding shows you there is more than one answer to a problem, depending on the way you approach it and the problem. Coding teaches creative problem-solving, multiple attempts at fixing a problem is common, you learn to try various techniques to until you find the perfect solution.

Answer:
Here is the function unzip:
def unzip(lst):
result= zip(*lst)
return list(result)
The complete program in Python is given below:
def unzip(lst):
result= zip(*lst)
return list(result)
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
Explanation:
Here zip() function is used in the unzip function. The return type of zip() function is a zip object. This means the function returns the iterator of tuples. This function can be used as its own inverse by using the * operator.
If you do not want to use zip() function then the above program can also be implemented as following which uses a for loop for elements in the given list (lst). This can make a pair of lists (2 tuple) instead of list of tuples:
def unzip(lst):
output = ([ a for a,b in lst ], [ b for a,b in lst ])
return output
lst =[(1, "one"), (2, "two"), (3, "three")]
tup= unzip(lst)
print(tup)
The programs along with their output are attached.
