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

In Python, an iterable object is any object you can loop through using a for loop or while loop. Common examples of iterables are: For example, you can loop through a list of numbers: Output: You can use a similar approach to loop through the characters of a string: Output: This comprehensive guide teaches you

To convert a space-separated string to a list in Python, call the str.split() method: Output: This works because the str.split() splits the string by blank spaces by default. Let’s then take a look at how to split a string of integers into a list of integers. How Does the split() Method Work? In Python, you

To convert comma-delimited string to a list in Python, split the string with the str.split() method. For example: Output: This results in a list of the parts of the strings that were separated by commas. Don’t Forget to Handle Empty Strings Using the above approach on an empty string returns a list with one empty

To find the combinations of length r in a Python list, use itertools.combinations() method: To find all the combinations of a Python list, also known as a powerset, follow these steps: Here is how it looks in the code: Output: How to Get All Combinations of Unique Elements in Python So you want no duplicate

The key difference between a function and a method in Python is: A function is implemented outside of a class. It does not belong to an object. A method is implemented inside of a class. It belongs to an object. Calling a function on an object looks like this: And calling a method of an

In Python, the finally statement is helpful with error handling to ensure code executes. For example, here the something_else() call does not run because it is not in an finally block: But by placing it inside a finally block, it gets executed no matter what: This is a comprehensive guide to the finally statement in

The Python reduce() function works such that it: Applies a function to the first and the second element of an iterable. Stores the result. Applies the function to the third element and the result. Continues this process until no values left. In other words, the reduce() reduces an iterable into a single cumulative value. For
