# Python Operators

Python Operators: In this tutorial, you’ll learn of everything about various sorts of operators in Python, their syntax, and how to use them with examples.

## What are operators in python?

Operations are special symbols in Python that do number-crunching or sensible calculation. The worth that the administrator works on is known as the operand.

For instance:

```>>> 2+3
5```

Here, + is the operator that performs addition. 2 and 3 are the operands and 5 is the output of the operation.

## Arithmetic operators

Arithmetic operators are used to performing mathematical operations like addition, subtraction, multiplication, etc.

## Example 1: Arithmetic operators in Python

```x = 15
y = 4

# Output: x + y = 19
print('x + y =',x+y)

# Output: x - y = 11
print('x - y =',x-y)

# Output: x * y = 60
print('x * y =',x*y)

# Output: x / y = 3.75
print('x / y =',x/y)

# Output: x // y = 3
print('x // y =',x//y)

# Output: x ** y = 50625
print('x ** y =',x**y)```

Output

```x + y = 19
x - y = 11
x * y = 60
x / y = 3.75
x // y = 3
x ** y = 50625
```

## Comparison operators

Comparison operators are used to comparing values. It returns either True or False according to the condition.

Operator Meaning Example
> Greater than – True if the left operand is greater than the right x > y
< Less than – True if the left operand is less than the right x < y
== Equal to – True if both operands are equal x == y
!= Not equal to – True if operands are not equal x != y
>= Greater than or equal to – True if the left operand is greater than or equal to the right x >= y
<= Less than or equal to – True if the left operand is less than or equal to the right x <= y

## Example 2: Comparison operators in Python

``````x = 10
y = 12

# Output: x > y is False
print('x > y is',x>y)

# Output: x < y is True
print('x < y is',x<y)

# Output: x == y is False
print('x == y is',x==y)

# Output: x != y is True
print('x != y is',x!=y)

# Output: x >= y is False
print('x >= y is',x>=y)

# Output: x <= y is True
print('x <= y is',x<=y)``````
Output
```x > y is False
x < y is True
x == y is False
x != y is True
x >= y is False
x <= y is True```

## Logical operators

Logical operators are the and, or, not operators.

## Example 3: Logical Operators in Python

```x = True
y = False

print('x and y is',x and y)

print('x or y is',x or y)

print('not x is',not x)```

Output

```x and y is False
x or y is True
not x is False```

## Bitwise operators

Bitwise operators act on operands as though they were strings of parallel digits. They work a little bit at a time, subsequently the name.

For example, 2 is 10 in binary, and 7 is 111.

In the table below: Let x = 10 (0000 1010 in binary) and y = 4 (0000 0100 in binary)

## Assignment operators

Assignment operators are used in Python to assign values to variables.

a = 5 is a simple assignment operator that assigns the value 5 on the right to the variable an on the left.

There are different compound administrators in Python like a += 5 that adds to the variable and later allots the equivalent. It is equivalent to a = a + 5.

## Special operators

Python language offers some special sorts of operations like the identity operator or the membership operator. They are described below with examples.

## Identity operators

is and is not are the identity operations in Python. They are used to check if two qualities (or variables) are situated on a similar piece of the memory. Two factors that are equivalent doesn’t suggest that they are identical.

Operator Meaning Example
is True if the operands are identical (refer to the same object) x is True
is not True if the operands are not identical (do not refer to the same object) x is not True

## Example 4: Identity operators in Python

```x1 = 5
y1 = 5
x2 = 'Hello'
y2 = 'Hello'
x3 = [1,2,3]
y3 = [1,2,3]

# Output: False
print(x1 is not y1)

# Output: True
print(x2 is y2)

# Output: False
print(x3 is y3)```

Output

```False
True
False```

Here, we see that x1 and y1 are whole numbers of similar qualities, so they are equivalent just as indistinguishable. The same is the situation with x2 and y2 (strings).

In any case, x3 and y3 are recorded. They are equivalent yet not indistinguishable. It is on the grounds that the translator finds them independently in memory despite the fact that they are equivalent.

## Membership operators

in and not in are the membership operators in Python. They are used to test

whether a value or variable is found in a sequence (string, list, tuple, set, and dictionary).

In a dictionary we can only test for the presence of a key, not the value.

## Example #5: Membership operators in Python

```x = 'Hello world'
y = {1:'a',2:'b'}

# Output: True
print('H' in x)

# Output: True
print('hello' not in x)

# Output: True
print(1 in y)

# Output: False
print('a' in y)```

Output

```True
True
True
False```

Here, ‘H’ is in x but ‘hello’ is not present in x (remember, Python is case sensitive). Similarly, 1 is key and ‘a’ is the value in dictionary y. Hence, ‘a’ in y returns False.
