More specifically, the continue statement skips the “rest of the loop” and jumps into the beginning of the next iteration. Unlike the break statement, the continue does not exit the loop. For example, to print the odd numbers, use […]

In almost every Python program, you are dealing with functions that take input, perform an action, and spit out an output. More often than not, it can be useful to include a default argument value in a function. If an input argument isn’t provided, the default value is used instead. And if the input value

To call a function in Python, add parenthesis after the function name. For example, if you have a function called greet, you can call it by: And if the function takes arguments, specify them inside the parenthesis: Let’s take a deeper dive into functions and how to call them in Python. More specifically, we are

To check if a file exists using Python, use the exists() function from the os.path module: Here is a short illustration of checking if a file exists in the same folder: Alternatively, you can use the is_file() function from the Path class from the pathlib module: Where path_to_file is relative to the Python file that

To create a diamond pattern in Python using a for loop, use this simple piece of code: Then run the program. For example, here is a diamond output of height 7: How Does It Work The diamond pattern using for loop in Python is a common beginner question in Python courses. Make sure you understand

If you need anything more complex than the basic arithmetic operators in Python, there’s a built-in library called Math you can use. With this module, you can calculate square roots, medians, distances, and such. This guide teaches you how to start using the math module in Python. To start using the module in your project,

A leap year is a year that is divisible by 4. The exception is the years that are divisible by 100 but not by 400. This comprehensive guide teaches you how to check if a year is leap year in Python. You will also learn how to find the next leap year given the current

In Python, you can have if-else statements on one line. To write an if-else statement on one line, follow the conditional expression syntax: For example: This is handy with short if-else statements because it allows you to save lines of code while preserving code quality. But do not overuse it. Turning longer if-else statements into

Python decorators provide a readable way to extend the behavior of a function, method, or class. Decorating a function in Python follows this syntax: Here the guard_zero decorator updates the behavior of divide() function to make sure y is not 0 when dividing. How to Use Decorators in Python The best way to demonstrate using
