It is possible because +  operator is overloaded by both int  class andstr  class. The operators are actually methods defined in respective classes. Defining methods for operators is known as operator overloading. For e.g. To use +  operator with custom objects  you need to define a method called __add__  . Operator Function Method Description + __add__(self,other) Addition * __mul__(self,other) Multiplication - __sub__(self,other) Subtraction % __mod__(self,other) Remainder / __truediv__(self,other) Division ＜ __lt__(self,other) Less than ＜= __le__(self,other) Less than or equal to == __eq__(self,other) Equal to != __ne__(self,other) Not equal to ＞ __gt__(self,other) Grater than ＞= __ge__(self,other) Grater than or equal to [index] __getitem__(self,other) index operator in __contains__(self,other)check membership len __len__(self,other) The number of elements str __str__(self,other) The string representation Sample Projects : https://github.com/SadaLearningHub1/Python3-Core-And-Advanced-Examples
