In Python, a FIFO queue is a linear data structure. It stores objects in a first in first out (FIFO) manner. For example, you can use the Queue class from the queue module as a thread-safe FIFO queue: Output: However, you could use a regular list as a FIFO queue as well. In this guide, […]

In Python, you can use the in operator to check if a value exists in a group of values. For example: Similarly, you can check if a value is not in a collection with not in operation (combining the not operator and the in operator): The ‘in’ Operator in Python The in operator works with

In Python, the built-in list() function converts an iterable object, such as string or tuple, to a list. For example, let’s convert a string to a list of characters: In this guide, you are going to see examples of using the list() function and how to make a custom object support it. When Use list()

A linter is an automated tool that enforces common style guidelines and best practices. It is every developer’s best friend. If you are not using one, you are missing out. Linters are not a Python-only thing. They are commonly used in any software development project regardless of the language. This is all it takes to

In Python, the built-in eval() function evaluates an expression passed as a string argument to it. For example: The eval() function takes the string argument, converts it into a Python expression, and runs it. The above code works exactly like this piece of traditional Python code: The eval() function can be useful in many ways.

In Python, you can specify a textual representation of an object by implementing the __repr__() method into the class. For example, let’s create a Fruit class with a textual representation method: When you print a Fruit object, the __repr__() method is called and the text description of the object shows up in the console. Output:

In Python, the difference between the is statement and the == operator is: For example: The variables a and b are different objects even though they have the same value. Thus comparing the values with the == operator returns True but checking if the variables refer to the same object results in False. In this

In Python, the double-backslash operator (//) is the floor division operator. Floor division means dividing and rounding down to the nearest integer. For example: The physical interpretation of the floor division is about sharing quantities evenly. For example, given 7 apples and 3 eaters, how many full apples does each person get? The answer is

In mathematics, the modulo gives you the remainder of the division. In Python, you can calculate the modulo using the percentage operator %. For example: You can interpret this answer as to how many slices of pizza are left over when 10 slices are shared with four eaters. The answer is 10 % 4, which
