Suppose we are writing code and a function or a class or the body of a loop is to be implemented later. If we want to run the code at this point, then the code will give syntax errors. So, we can use the pass statement in this case. For example, we can write the...

In Python, we do not have any switch statements. Instead, we can use the match statement for similar purposes. Please note that the Python match statement works for Python version 3.10 or higher. For example, the following function will take a status code as an...

We can use a Python while loop to execute a set of statements again and again under a certain condition. For example, let’s say we want to find out all the factors of a positive integer. We can implement that easily using the following piece of code: n = 21 i = 1...

The range() function in Python generates a sequence of numbers. For example, range(6) generates the numbers from 0 to 5. We can write a small piece of code in Python and verify that: for i in range(6): print(i) The program will output: 0 1 2 3 4 5 Similarly, if we...

If we want to execute a set of statements, again and again, let’s say under certain conditions, then we can use a loop. In Python, we have two types of loops – for loops and while loops. In this article, we will discuss Python for loops. Let’s say we are given a...
