In this article, we’ll look at how we can calculate the Python factorial using different approaches. The Python Factorial function The Python factorial function factorial(n) is defined for a whole number n. This computes the product of all terms from n to 1. factorial(0) is taken to be 1. So, the function is: Therefore, factorial(4) […]
There are different ways through which we can print to the console without a newline. Let’s quickly go through some of these methods. 1. Using print() We can use the print() function to achieve this, by setting the end (ending character) keyword argument appropriately. By default, this is a newline character (\n). So, we must
Python always operates on an Exception based model. That is, any errors during the program execution are passed as Exceptions and returned to the programmer, which may be handled accordingly using Exception Handling techniques. Sometimes, it is possible that a process raises more than one possible exception, depending on the flow of control. Thus, we
Since Python does not support static type checking (i.e type checking at compile type), if you ever want to check if a Python variable or object is a String or not; we need to use certain methods. Let us understand some of the ways of checking for a string type object. 1. Using isinstance() method
Python programming is a great tool to evaluate and make manipulations. In this article, We will be learning a simple command-line calculator program in Python 3. We’ll be using mathematical operators, Conditional statements, functions and handle user input to make our calculator. Prerequisites The system should have Python 3 installed on the local computer and have a
Syntax of input() Function The syntax of input() function is: The prompt string is printed on the console and the control is given to the user to enter the value. You should print some useful information to guide the user to enter the expected value. Getting User Input in Python Here is a simple example
