In Python, a list is a dynamic array that can be expanded in size as needed. The maximum size of a list is limited by the system's memory and the platform's architecture. In this article, we will explore how to determine the maximum size of a list in Python. Understanding ... Read More

In Python, strings are dynamic and can extend to a very large size, and can be limited only by the system's available memory. In other languages, compared to Python, it does not define a strict upper bound on string length. Instead, the practical maximum length of a string depends on ... Read More

Python allows dictionaries to be sorted using the built-in sorted() function. In this article, we will explore different ways to sort a dictionary in Python by its values. Sort a Dictionary Using itemgetter() method When we use the sorted() function along with the itemgetter() method of the operator module, the dictionary ... Read More

In Python, floating-point numbers can be implemented using double-precision, i.e., 64-bit format, as per the IEEE 754 standard. These floats have a finite range and precision. The maximum value that a float can represent depends on the platform that we are using, but can be accessed using the sys.float_info attribute. ... Read More

Python allows dictionaries to be sorted using the built-in sorted() function. Although dictionaries in Python 3.7+ preserve insertion order, we can still create a new dictionary sorted by its keys using various methods. In this article, we will explore different ways to sort a dictionary in Python by its keys. ... Read More
