What are operators in Python?
Long Answer

Answer:
- Operators in Python are special symbols or characters that perform specific operations on operands (variables, values, or expressions) to produce a result.
- They are used to manipulate data in Python programs, such as performing mathematical calculations, comparing values, testing conditions, and assigning values to variables.
- Python provides a wide range of operators, including arithmetic operators, comparison operators, logical operators, bitwise operators, assignment operators, membership operators, identity operators, and more.
- Arithmetic operators are used for performing mathematical calculations such as addition, subtraction, multiplication, division, modulus, and exponentiation.
- Comparison operators are used for comparing two values and returning a Boolean value (True or False) based on the comparison.
- Logical operators are used for combining conditions and returning a Boolean value (True or False) based on the result of the logical operation.
- Bitwise operators are used for manipulating binary numbers, performing operations such as AND, OR, XOR, left shift, and right shift.
- Assignment operators are used for assigning a value to a variable, and they can perform additional operations such as adding, subtracting, multiplying, or dividing the value by a specified amount.
- Membership operators are used for testing whether a value or variable is a member of a sequence (such as a list, tuple, or dictionary).
- Identity operators are used for testing whether two variables or values have the same identity (i.e., they refer to the same object in memory).
- Python also supports operator overloading, which allows operators to have different meanings in different contexts, such as when working with custom objects and classes.
- The order in which operators are evaluated in an expression is determined by their precedence or priority, which is based on the type of operator and its position in the expression.
