## Python Operators: An Overview

Operators in Python Programming are the fundamental concepts that are important to know. These operators are needed to perform various operations in Python such as arithmetic calculations, logical evaluations, bitwise manipulations, etc.

In this Python Tutorial, you will get to know about Python Operators, Types of Operators in Python with Example, and Precedence of Operators in Python. If you are new to Python and want to learn it from scratch, our Python Certification Training will help you with that.

## What are Operators in Python?

In Python, operators are special symbols or keywords that carry out operations on values and python variablesThey serve as a basis for expressions, which are used to modify data and execute computations. Python contains several operators, each with its unique purpose.

## Types of Python Operators

Python language supports various types of operators, which are:
1. Arithmetic Operators
2. Comparison (Relational) Operators
3. Assignment Operators
4. Logical Operators
5. Bitwise Operators
6. Membership Operators
7. Identity Operators

### 1. Python Arithmetic Operators

• Mathematical operations including addition, subtraction, multiplication, and division are commonly carried out using Python arithmetic operators.
• They are compatible with integers, variables, and expressions.
• In addition to the standard arithmetic operators, there are operators for modulus, exponentiation, and floor division.
 Operator Name Example + Addition 10 + 20 = 30 - Subtraction 20 – 10 = 10 * Multiplication 10 * 20 = 200 / Division 20 / 10 = 2 % Modulus 22 % 10 = 2 ** Exponent 4**2 = 16 // Floor Division 9//2 = 4

#### Example of Python Arithmetic Operators in Python Compiler

```     ```a = 21
b = 10
print ("a + b : ", a + b)
# Subtraction
print ("a - b : ", a - b)
# Multiplication
print ("a * b : ", a * b)
# Division
print ("a / b : ", a / b)
# Modulus
print ("a % b : ", a % b)
# Exponent
print ("a ** b : ", a ** b)
# Floor Division
print ("a // b : ", a // b)
``````

The two variables "a" and "b" are defined in this code, which then applies several arithmetic operations to them (including addition, subtraction, multiplication, division, modulus, exponentiation, and floor division) and outputs the results.

#### Output

``````a + b : 31
a - b : 11
a * b : 210
a / b : 2.1
a % b : 1
a ** b : 16679880978201
a // b : 2``````

### 2. Python Comparison Operators

 Operator Name Example == Equal 4 == 5 is not true. != Not Equal 4 != 5 is true. > Greater Than 4 > 5 is not true < Less Than 4 < 5 is true >= Greater than or Equal to 4 >= 5 is not true. <= Less than or Equal to 4 <= 5 is true.

#### Example of Python Comparison Operators

```        ```a = 4
b = 5
# Equal
print ("a == b : ", a == b)
# Not Equal
print ("a != b : ", a != b)
# Greater Than
print ("a > b : ", a > b)
# Less Than
print ("a < b : ", a < b)
# Greater Than or Equal to
print ("a >= b : ", a >= b)
# Less Than or Equal to
print ("a <= b : ", a <= b)
``````

This code compares the values of python variables 'a' and 'b' and prints if they are equal, not equal, greater than, less than, more than or equal to, and less than or equal to each other.

#### Output

``````a == b : False
a != b : True
a > b : False
a < b : True
a >= b : False
a <= b : True``````

### 3. Python Assignment Operators

• Python assignment operators are used to assign values to variables in Python.
• The single equal symbol (=) is the most fundamental assignment operator.
• It assigns the value on the operator's right side to the variable on the operator's left side.
 Operator Name Example = Assignment Operator a = 10 += Addition Assignment a += 5 (Same as a = a + 5) -= Subtraction Assignment a -= 5 (Same as a = a - 5) *= Multiplication Assignment a *= 5 (Same as a = a * 5) /= Division Assignment a /= 5 (Same as a = a / 5) %= Remainder Assignment a %= 5 (Same as a = a % 5) **= Exponent Assignment a **= 2 (Same as a = a ** 2) //= Floor Division Assignment a //= 3 (Same as a = a // 3)

#### Example of Python Assignment Operators

```        ```# Assignment Operator
a = 10
a += 5
print ("a += 5 : ", a)
# Subtraction Assignment
a -= 5
print ("a -= 5 : ", a)
# Multiplication Assignment
a *= 5
print ("a *= 5 : ", a)
# Division Assignment
a /= 5
print ("a /= 5 : ",a)
# Remainder Assignment
a %= 3
print ("a %= 3 : ", a)
# Exponent Assignment
a **= 2
print ("a **= 2 : ", a)
# Floor Division Assignment
a //= 3
print ("a //= 3 : ", a)``````

The Python assignment operators are shown in this code in the Python Editor. It begins with the value of 'a' equal to 10, and then goes through the steps of addition, subtraction, multiplication, division, remainder, exponentiation, and floor division, updating 'a' as necessary and outputting the results.

#### Output

``````a += 5 : 105
a -= 5 : 100
a *= 5 : 500
a /= 5 : 100.0
a %= 3 : 1.0
a **= 2 : 1.0
a //= 3 : 0.0``````

### 4. Python Bitwise Operators

• Python bitwise operators execute operations on individual bits of binary integers.
• They work with integer binary representations, performing logical operations on each bit location.
• Python includes various bitwise operators, such as AND (&), OR (|), NOT (), XOR (), left shift (), and right shift (>>).
 Operator Name Example & Binary AND Sets each bit to 1 if both bits are 1 | Binary OR Sets each bit to 1 if one of the two bits is 1 ^ Binary XOR Sets each bit to 1 if only one of two bits is 1 ~ Binary Ones Complement Inverts all the bits ~ Binary Ones Complement Inverts all the bits << Binary Left Shift Shift left by pushing zeros in from the right and let the leftmost bits fall off >> Binary Right Shift Shift right by pushing copies of the leftmost bit in from the left, and let the rightmost bits fall off

#### Example of Python Bitwise Operators

```        ```a = 60 # 60 = 0011 1100
b = 13 # 13 = 0000 1101
# Binary AND
c = a & b # 12 = 0000 1100
print ("a & b : ", c)
# Binary OR
c = a | b # 61 = 0011 1101
print ("a | b : ", c)
# Binary XOR
c = a ^ b # 49 = 0011 0001
print ("a ^ b : ", c)
# Binary Ones Complement
c = ~a; # -61 = 1100 0011
print ("~a : ", c)
# Binary Left Shift
c = a << 2; # 240 = 1111 0000
print ("a << 2 : ", c)
# Binary Right Shift
c = a >> 2; # 15 = 0000 1111
print ("a >> 2 : ", c)``````

The binary representations of the numbers 'a and b' are subjected to bitwise operations in this code. It displays the results of binary AND, OR, XOR, Ones Complement, Left Shift, and Right Shift operations.

#### Output

``````a & b : 12
a | b : 61
a ^ b : 49
~a : -61
a >> 2 : 240
a >> 2 : 15``````

### 5. Python Logical Operators

• Python logical operators are used to compose Boolean expressions and evaluate their truth values.
• They are required for the creation of conditional statements as well as for managing the flow of execution in programs.
• Python has three basic logical operators: AND, OR, and NOT.
 Operator Description Example and Logical AND If both of the operands are true then the condition becomes true. (a and b) is true. or Logical OR If any of the two operands is non-zero then the condition becomes true. (a or b) is true. not Logical NOT Used to reverse the logical state of its operand Not(a and b) is false.

#### Example of Python Logical Operators in Python Online Editor

```          ```x = 5
y = 10
if x > 3 and y < 15:
print("Both x and y are within the specified range")``````

The code assigns the values 5 and 10 to variables x and y. It determines whether x is larger than 3 and y is less than 15. If both conditions are met, it writes "Both x and y are within the specified range."

#### Output

``Both x and y are within the specified range``

### 6. Python Membership Operators

• Python membership operators are used to determine whether or not a certain value occurs within a sequence.
• They make it simple to determine the membership of elements in various data structures such as lists, tuples, sets, and strings.
• Python has two primary membership operators: the in and not in operators.
 Operator Description Example in Evaluates to true if it finds a variable in the specified sequence and false otherwise. x in y, here in results in a 1 if x is a member of sequence y. not in Evaluates to true if it does not find a variable in the specified sequence and false otherwise. x not in y, here not in results in a 1 if x is not a member of sequence y.

#### Example of Python Membership Operators

```        ```fruits = ["apple", "banana", "cherry"]
if "banana" in fruits:
print("Yes, banana is a fruit!")
else:
print("No, banana is not a fruit!")``````

The code defines a list of fruits and tests to see if the word "banana" appears in the list. If it is, the message "Yes, banana is a fruit!" is displayed; otherwise, the message "No, banana is not a fruit!" is displayed.

#### Output

``Yes, banana is a fruit!``

### 7. Python Identity Operators

• Python identity operators are used to compare two objects' memory addresses rather than their values.
• If the two objects refer to the same memory address, they evaluate to True; otherwise, they evaluate to False.
• Python includes two identity operators: the is and is not operators.
 Operator Description Example is Evaluates to true if the variables on either side of the operator point to the same object and false otherwise x is y, here are results in 1 if id(x) equals id(y) is not Evaluates to false if the variables on either side of the operator point to the same object and true otherwise x is not y, there are no results in 1 if id(x) is not equal to id(y).

#### Example of Python Identity Operators

```        ```x = 10
y = 5
if x is y:
print("x and y are the same object")
else:
print("x and y are not the same object")``````

The code sets the variables x and y to 10 and 5, respectively. It then uses the is keyword to determine whether x and y relate to the same item in memory. If they are, it displays "x and y are the same object"; otherwise, it displays "x and y are not the same object."

#### Output

``x and y are not the same object``

## Python Operators Precedence

 Sr.No. Operator Description 1. ** Exponentiation (raise to the power) 2. ~ + - Complement, unary plus and minus (method names for the last two are +@ and -@) 3. * / % // Multiply, divide, modulo, and floor division 4. + - Addition and subtraction 5. >> << Right and left bitwise shift 6. & Bitwise 'AND' 7. ^ | Bitwise exclusive `OR' and regular `OR' 8. <= < > >= Comparison operators 9. <> == != Equality operators 10. = %= /= //= -= += *= **= Assignment operators 11. is is not Identity operators 12 in not in Membership operators 13. not or and Logical operators

## Best Practices

Just knowing and understanding the usage of operators is not enough. You should also know how apply it into best practice for better and accurate results.

### Guidelines for using operators effectively

• You must use parentheses to write more readable and clearer expressions.
• Python allows for chaining operators but using it in excess will only make the code more complex and difficult to read so avoid it as much as you can.
• Use names for variables that clearly describe the purpose of the operands.
• Pay extra attention while using Membership and Identity operators.
• Use Bitwise operators only when necessary as they can be a little complicated to use.
• Test your code thoroughly to check if all the operators are working correctly or not.

### Tips for writing clean and efficient code

• It is always advisable to sticking to the coding standards and style guidelines like PEF 8 (Python), Google's Python Style Guide.
• Make variable names as descriptive and meaningful as possible.
• Maintain the conciseness of your functions so that it is easy to read, test and debug.
• Avoid repetition of the code.
• Write comments explaining the logic wherever needed clearly and concisely.
