Introduction to One-Hot Encoding When we want to convert categorical data into a numerical format we use One Hot encoding which can be understood by computer. In one hot encoding we create new binary columns for each unique value in categorical features.  In one hot encoding we assign values like 0 or 1 to columns […]

What is a callable object ?In simple terms any object that can be called using parentheses () is called a callable object. Similarly how we invoke a function. Callables include functions, methods, classes and objects that implement the special __call__() method. In the blog we will learn how to solve typeerror : dict object is

Summary of continue, pass, and break. Break, continue, and pass are loop control statements A break statement is used when we want to exit the loop before the usual time.
