## Using Python to Check for Number in List

Today’s Python snippet is brought to you by the “in” keyword. In Python, we can use the in keyword for lots of different purposes. In terms of today’s snippet, we’re going to use it to check if a particular number is in a list. To begin, let’s say we have a list called coolNumbers. Take […]

## Using Python to Check for Odd or Even Numbers

It’s pretty easy to use Python to perform calculations and arithmetic. One cool type of arithmetic that Python can perform is to calculateÂ the remainder of one number divided by another. To do this, you need to use the modulo operator (otherwise known as the percentage sign: %). When you place a modulo in between two […]

## How to Use Python’s len() Method

Python’s len() method can be used to easily find the length of a string. It’s a simple and quick way to measure the length of a string (the number of characters) without having to write a lot of code. The syntax for using the len() method is fairly straightforward, and hard to mess up — […]

## How to Generate a Random Number in Python

The aim of a programmer while creating a program is to ensure that the program stands the test for any random input. The program should correctly process the input and accurately calculate the output for any arbitrary data. A programmer must test the program for a wide range of information and amend the code accordingly […]

## How to Test for Positive Numbers in Python

The following Python snippet demonstrates how to test if an inputted number is positive, negative, or zero. The code is simple, straightforward, and works with any number or integer. The code uses an if…elif…else statement to determine if a number is greater than 0 (in which case it has to be positive), elif a number […]

## Using Python’s Pass Statement

In Python, the pass statement, much like a comment, is considered a null statement, meaning that it doesn’t result in any Python operations. The only difference between a comment and a pass statement is that while a comment is completely ignored by the interpreter, the pass statement is not (but, like a comment statement, nothing […]

## How to Test for Prime Numbers in Python

As with any OOP language, you can use Python to conduct calculations and gather information about numbers. One cool thing you can do with Python is test if a number is prime or not. A prime number, as you may remember from math class way back when, is any whole number (it must be greater […]

## Python Basics: What Are Modules?

In Python, modules are Python files containing Python functions to be implemented in your code. Youâ€™ll know a file is a module because of its .py extension. We can import modules easily using the import command, like this: import mymodule The example above will work when theres a file called mymodule.py from which functions can […]
