In the Python Language, variables hold data values that convey the message. These values are either for logical or arithmetic operations. Meaning on python, all the process of writing codes is done using the standard python Operators. In a very simple and clear manner, you’ll be learning the python Operators, what is it, the features of python Operators, and also you’ll be knowing the types and functions of Python Operators. For the practical aspect, you’ll know how to apply them to Python Language, before that you will learn how to access the python operator Values. In conclusion, you’ll be able to update the python Operators and delete some unwanted operations.
What are Python Operators
Python Operators are standard symbols that are used for logical and arithmetic operations in Python. Operators are used with operands to return a value e.g 2+8=10, 2 and 8 are the operands,(+) is the operator and the returned Value or output is 10. Python has seven (7) Operators and they are:
- Arithmetic Operators
- Comparison/Relational Operators
- Assignment Operators
- Logical Operators
- Bitwise Operators
- Membership Operators
- Identity Operators
This page is dedicated to giving complete knowledge of these operators.
Arithmetic Operators
The Arithmetic Operators are used to carry out all arithmetic or mathematical activities in python. Mathematical operations like addition, subtraction, multiplication, and division are enabled by the mathematical symbols: ( +, -, /, *). See the table for complete arithmetic Operators symbols
Operator | Description based on operands x and y |
+ | The addition adds two operands x+y |
– | Subtraction: subtracts two operands x-y |
* | Multiplication: multiply two operands x*y |
/ | Division(float): divides two operands x/y |
// | Floor division: divides two operands x//y |
% | Modulus: gives the remainder after the operands are been divided x%y |
** | Exponent: gives the result of x raised to power y: x**y |
Example of Arithmetic Operators
Note: all the above examples will be shown at once. Take x=9 and y=4
Python Input:
# Examples of Arithmetic Operator x = 9 y = 4 # Addition of numbers add = x + y # Subtraction of numbers sub = x - y # Multiplication of a number mul = x * y # Division(float) of number div1 = x / y # Division(floor) of number div2 = x // y # Modulo of both numbers mod = x % y # Power p = x ** y # print results print(add) print(sub) print(mul) print(div1) print(div2) print(mod) print(p)
Output: 13 5 36 2.25 2 1 6561
The above returns explain the arithmetic Operators practically
Comparison Operators in Python
Comparison Operators in Python are used to compare values. It gives True or False according to the condition. The python comparison Operators are also called Relational Operators. Take x and y as our two values
Operator | Description based on operands x and y |
> | Greater than: True if the left is greater than the right x>y |
< | Less than: True if the left is less than the right x<y |
== | True if two operands are equal x==y |
!= | Not equal to: True if two operands are not equal x!=y |
>= | Greater than or equal to True if the left operand is greater than or equal to the right operand x>=y |
<= | Less than or equal to True if the left operand is less than or equal to the right operand x<=y |
Example of comparison Operators in Python
Take x=11 and y=22
Python input:
# Examples of Relational Operators x = 11 y = 22 # x > y is False print(x > y) # x < y is True print(x < y) # x == y is False print(x == y) # x != y is True print(x != y) # x >= y is False print(x >= y) # x <= y is True print(x <= y)
Output: False True False True False True
The above returns a practical explanation of the python comparison Operators
Assignment Operators
As the name implies, assignment Operators are used to assigning values to variables in Python. Meaning all characters must have the assignment symbol (=). Let’s see the tablet with x and y as our operands
Operator | Description based on operands x and y |
= | Assign Values at the right operand to the left v=x+y |
+=ad AND | Adds right operand to left operand and assigning returns to left operand v+=x is equivalent to v=v+x |
-= subtract AND | Subtracts right operand from left operand and assign returns to left operand v-=x is equivalent to v=v-x |
*= Multiply AND | Multiplies right operand with the left operand and assign returns to the left operand v*=x is equivalent to v=v*x |
/= Divide AND | Divides the right operand with the left operand and assigns returns to the left operand v/=x is equivalent to v=v/x |
% Modulus AND | It takes modulus with left and right operands and assigns the result to the left operand v%=x is equivalent to v=v%x |
**= Exponent AND | Calculates the exponential power value of both operands and assigns Values to left v**=x is equivalent to v=v**x |
&= Bitwise AND | Calculates the bitwise operation on both operators and assigns the value to the left operand v&=x is equivalent to v=v&x |
|= Bitwise OR | Calculates the bitwise OR and assigns value to the left operand v|=x is equivalent to v=v|x |
^= Bitwise xOR | Calculates bitwise xOR and assigns Values to the left operand v^=x is equivalent to v=v^x |
>>= Bitwise right shift | Performs bitwise right shift on operands and assigns Values to left operand v>>=x is equivalent to v=v>>x |
<<= Bitwise left shift | Performs bitwise left shift on operands and assigns Values to the left operand v<<=x is equivalent to v=v<<x |
Some examples of assignment Operators in Python
Python Input:
# Examples of Assignment Operators x = 20 # Assign value y = x print(y) # Add and assign value y += x print(y) # Subtract and assign value y -= x print(y) # multiply and assign y *= x print(y) # bitwise shift operator y <<= x print(y)
Output: 20 40 20 200 204800
The above examples show the assignment Operators practically
Python Logical Operators
Logical operators are used to joining conditional statements to give logical output. It uses the Logical AND, Logical OR, and Logical NOT operations.
See the table for all Logical Operators in Python
Operators | Description based on operands x and y |
and Logical AND | Returns True if (x and y) are true |
or Logical OR | Returns True if either (x or y) is true |
not Logical NOT | Returns True if neither ( x or y) is true |
Example of Python Logical Operators
Python input:
# Examples of Logical Operator x = True y = False # Print a and b is False print(x and y) # Print a or b is True print(x or y) # Print, not a is False print(not x)
Output: False True False
The above expresses the Python Logical Operators in a practical order
Bitwise Operators in Python
These are the bit-by-bit binary numbers operations in Python. Some examples of the Bitwise operators and syntax are expressed in the table below
Operators | Description based on operands x and y |
& Binary AND | Copies a bit to the results if both operands have the bit value x&y |
| Binary OR | Copies a bit of the result if any one of the operands has the bit value x|y |
^ Binary XOR | Copies the bit if it is set in either x or y (x^y) |
~ Bitwise NOT | It indicates a Flippo bit on one operand ~x |
>> Bitwise right shift | The left operand(x) is moved right to the number of bits indicated by the right operand (x>>) |
<< Bitwise left shift | The left operand(x) is moved left to the number of bits indicated by the right operand (x<<) |
Example of Python Bitwise operators
Python Input:
# Examples of Bitwise operators x = 10 y = 4 # Print bitwise AND operation print(x & y) # Print bitwise OR operation print(x | y) # Print bitwise NOT operation print(~x) # print bitwise XOR operation print(x ^ y) # print bitwise right shift operation print(x >> y) # print bitwise left shift operation print(x << y)
Output: 0 14 -11 14 2 40
Membership Operators
The membership Operators check whether a variable or value is included in a sequence. It uses not or not as its operators.
- it signifies true if a value or variable is found in a sequence
- not in returns false if a value or variable is not in a sequence
Example of Python Membership Operators
# Python program to illustrate # not 'in' operator x = 24 y = 20 list = [10, 20, 30, 40, 50] if (x is not in the list): print("x is NOT present in the given list") else: print("x is present in the given list") if (y in the list): print("y is present in the given list") else: print("y is NOT present in the given list
Output: x is NOT present in the given list y is present in the given list
Python Identify Operators
The identity operators identify and compare the memory location of two objects. The identity operators operate in two categories which are:
- is: Simply true if the Values are similar( x is y)
- is not: Signifies true if the values are not similar (x is not y)
Example Of Python Identify Operators
Python Input:
x = 10 y = 20 v = a print(x is not y) print(x is c)
Output: True True
Python Precedence Operators
Python Precedence Operators are used in an operation with more than one operator to indicate which operator should operate first. It determines operations according to priority.
The Table Below Shows all of python’s precedence from highest to lowest
Operator | Description |
**Exponent | Raise the power |
~+- | complement, urinary plus, and minus |
*/%// | Multiplication, divide, modulus, and floor division |
+- | Addition and subtraction |
>><< | Right Bitwise shift and Left Bitwise shift |
& | Bitwise AND |
|^ | Bitwise normal OR and exclusive OR |
<= < > >= | Comparison operators |
<> == != | Equality operators |
= %= /= //= -= += *= **= | Assignment operators |
is is not | Identity operators |
in, not in | Membership operators |
not, or, and | Logical operators |
Example of Python Precedence Operators
Python Input:
# Examples of Operator Precedence # Precedence of '+' & '*' expr = 1 + 50 * 10 print(expr) # Precedence of 'or' & 'and' name = "Simon" age = 0 if name == "Simon" or name == "Monday" and age >= 2: print("Hello! Tanya.") else: print("Good-Bye!!")
Output: 501 Hello! Tanya.
From the above output, python prints according to precedence.
