We often use files to store the outputs of our programs in permanent storage. Generally, we work with relative paths of files in our programs. In this article, we will discuss two ways to get the absolute path to a file in python from its relative pathname. What is an absolute path to a file? […]

Several times we use 2-D lists or lists of lists in our programs to represent a table or matrix. When these tables need to be sorted according to some value, we need to sort the entire list of lists. In this article, we will discuss different approaches to sort a list of lists in python. […]

In python, nan is a special value used to represent missing values. In this article, we will discuss the properties of nan values. We will also look at different ways how we can remove nan values from list in python. What is nan in python? The nan values are special floating-point numbers defined in the […]

What is the type of variable in Python? We use variables to store data in a reserved memory location. The type of a variable defines the memory allocated to it. The type of a variable is based on the data we store in it. We do not need to explicitly mention the type of a […]

What are the types of arrays? An array is a common structure that stores multiple items of a similar type together in a single place in a contiguous memory location. We can create arrays of any one of the data types provided in Python. Ways to convert float arrays to int in Python In Python, […]

A list is one of Python’s fundamental in-built data types and clusters several items in a single variable. In this article, we will demonstrate the different ways available to retrieve the list intersection in Python. What is the list intersection in Python? The intersection of two lists returns the elements that are present in both […]

What is Bilinear Interpolation? Linear Interpolation in mathematics helps curve fitting by using linear polynomials that make new data points between a specific range of a discrete set of definite data points. The term Bilinear Interpolation is an extension to linear interpolation that performs the interpolation of functions containing two variables (for example, x and […]

What is the Euclidean Distance? Euclidean Distance is the line segment between two points in any dimension. Mathematically, we can evaluate it as the square root of the sum of squares of the difference between the given points. Ways to Calculate the Euclidean distance in Python Let us discuss how to calculate this value using […]

Strings are one of the most used data structures when we process text data. We also use different functions in our program. But, have you ever tried to convert a string to a function given that a function with the same name has been defined in a different module or class? In this article, we […]
