To calculate the area of a circle in Python, here’s the code: You can call this function by giving it the radius of the circle, for example: Output: How to Calculate the Area of a Circle in Maths To calculate the area of the circle given the radius of the circle, use the following equation. […]

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
