List comprehensions are a powerful feature in Python, allowing you to create new lists by specifying their elements with a concise and readable syntax. One of the ways to make your list comprehensions more expressive and flexible is by incorporating ternary operators, also known as conditional expressions. 💡 A ternary operator in a Python list … Read more
The Python ternary operator, also known as the conditional operator, is a concise way to write simple if-else statements. Introduced in Python 2.5, this operator allows you to return one of two values depending on the evaluation of a given condition. You might find the ternary operator particularly useful when you want to write clean … Read more
Python’s ternary operator, also known as the conditional operator, evaluates a condition and returns one of two values, depending on whether the condition is true or false. This useful feature enables you to write clean and concise Python code, using one line to achieve the functionality of an if-else statement. 💡 Tip: Like a nested … Read more
Several methods are available to implement a swap function in Python, including tuple assignment and XOR. Tuple Assignment Swap Method The tuple assignment method creates two tuples with two variables each. The first tuple contains the original variables, while the second one has their exchanged values. Finally, these tuples are “unpacked” into individual variables, effectively … Read more

There are several methods to calculate the sum of the square roots of the first n numbers. Basic Iteration The most straightforward solution is to simply iterate from 1 to n, calculate the square root of each number, and add it to a running total. Runtime: O(n) Approximate Closed Form Solution An approximate closed-form solution … Read more
Python f-strings, available since Python 3.6, offer a concise way to embed expressions in string literals using curly braces {}. They improve readability and performance over older methods like %-formatting and str.format(). To use f-strings, prefix the string with “f” or “F” and enclose expressions within braces: f”My name is {name} and I am {age} … Read more
Python one-liners are Turing complete since Python is a Turing-complete language and any Python program can be executed as a one-liner using the exec() function, by enclosing the entire program in a string and passing it to exec(). In this article, I slowly build this argument and also provide less “brute-force” ways to build Python … Read more
