While working on an Employee management system project in Python, I needed to calculate the difference between yesterday’s and today’s working hours. Sometimes, the result was negative, so I needed to make it positive. So, I found multiple ways to make it a positive number without using P...
Python’s Built-in round() FunctionPython has a built-in round() function that takes two numeric arguments, n and ndigits, and returns the number n rounded to ndigits. The ndigits argument defaults to zero, so leaving it out results in a number rounded to an integer. As you’ll see...
Python's.format() function is a flexible way to format strings; it lets you dynamically insert variables into strings without changing their original data types. Example - 4: Using f-stringOutput: <class 'int'> <class 'str'> Explanation: An integer variable called n is initialized with ...
In Python, functions are first-class citizens. This means that functions have the same characteristics as values like strings and numbers. Anything you would expect to be able to do with a string or number, you can also do with a function....
InFigure 2, adding more to the weights reaches a low point and then starts to climb again. The slope of the line reveals the direction to that lowest point on the curve, which represents the lowest loss. When the slope is negative, add to the weights. When the slope is positive, subtr...
To get the desired rounding, we can use the decimal module, and change the rounding method. If you are not comfortable with that, you can make your own method. To use the above example. def my_rounding(num): '''It only handles positive integer''' q, r = divmod(num, 1) if r ...
In mathematics, the factorial of a non-negative integer number N, denoted as N!, is defined as the product of all positive integers less than or equal to N. For example, the factorial of 5 is calculated as:5! = 5 * 4 * 3 * 2 * 1 = 120 The factorial of 0 is 0! = 1, to...

It takes the array and the number of places we want to shift the elements of the array and returns the shifted array. If we want to shift the elements towards the right, we have to use a positive integer as the shift value. If we want to shift the elements towards the left, we ...
