Python Arithmetic Operators: +, -, *, /, % (modulus), ** (exponent), // (Floor Division)
Python Comparison Operators: ==, !=, <> (not equals), >, <, >=, <=
Python Assignment Operators: =, +=, -=, *=, /=, %=, //=
Logical: and, or, not
Python Identity Operators: Identity operators compare the memory locations of two objects  
Python Operators Precedence: 
Exponentiation (raise to the power)
Multiply, divide, modulo and floor division
Addition and subtraction
Comparison operators
Equality operators
