To calculate the length of a hypotenuse of a right triangle using Pythagorean theorem: Here is an example. Given sides a = 3 and b = 4 in a right triangle, what is the length of the hypotenuse? The solution: That’s it for the theory. Next, let’s write a small program in Python to calculate …
To check if a set A is a superset of set B in Python, use the issuperset() method. For instance: Result: You can also use the built-in comparison operators to check for supersets in Python. For instance, to check if set A is a superset of B, use the less than or equal >= operator: …
To check if set A is a subset of set B in Python, use the built-in issubset() method. For example: Output: Alternatively, you can use comparison operators to do check if a set is a subset of another. For example, to check if set A is a subset of B, use <= operator: Output: If …
