Why? This happens because the call to .correct_radius() turns the radius into a negative number, which uncovers a bug: the function doesn’t properly check for valid input. In this example, your assert statement works as a watchdog for situations in which the radius could take invalid ...
Program for Factorial of a number in Python Factorial of any non-negative integer is equal to the product of all integers smaller than or equal to it. There is a built-in factorial() function in Python. For example factorial of 6 is 6*5*4*3*2*1 which is 720. import math def facto...

In countdown(), you check if from_number is smaller than one. In that case, you print Liftoff!. If not, then you print the number and keep counting.Note: The countdown() function is a recursive function. In other words, it’s a function calling itself. To learn more about recursive...

The break statement is used to exit the for loop prematurely. It’s used to break the for loop when a specific condition is met. Let’s say we have a list of numbers and we want to check if a number is present or not. We can iterate over the list of numbers and if the number ...
