 ## Operators:
 Python language supports several types of  operators. In this section, we will focus on few of them.
+### Assignment Operators:
+Assignment operators are used to assign values to variables. Let's take = as an example. Equal sign in mathematics shows that two values are equal, however in python it means we are storing a value in a certain variable and we call it assignment or a assigning value to a variable.  The table below shows the different types of python assignment operators, taken from [w3school](https://www.w3schools.com/python/python_operators.asp).
