What are the operators in Python and how to use them

Python Operators

Operators are used to perform operations on variables and values.

Python divides operators into the following groups:

• Arithmetic operators

• Assignment operators

• Comparison operators

• Logical operators

• Identity operators

• Member operators

• Bitwise operators

Python arithmetic operators

Arithmetic operators are used with numerical values ​​to Perform common mathematical operations:

Operators:

Name: Add

Example: x y

Try it

x = 5
y = 3
print(x + y)

Operator: -

Name: Minus

Example: x - y

Try it

x = 5
y = 3

print(x - y)

Operator: *

Name: Multiply

Example: x * y

Try it

x = 5
y = 3

print(x * y)

Operator: /

Name: except

Instance: x / y

Try it

x = 15
y = 3

print(x / y)

Operator: %

Name: Modulo

Example: x % y

Try it

x = 5
y = 2

print(x % y)

Operator: **

Name: Power

Example: x ** y

Try it

x = 2
y = 5

print(x ** y) #same as 2*2*2*2*2

Operator: //

Name: floor division (dividing by integer)

Example: x // y

Try it

x = 15
y = 2

print(x // y)

#the floor division // rounds the result down to the nearest whole number

Python assignment operator

The assignment operator is used to assign values ​​to variables

Operator: =

Example: x = 5

is equivalent to: x = 5

Try it:

x = 5print(x)

Operator: =

Example :x = 3

is equivalent to: x = x 3

Try:

x = 5

x += 3

print(x)

Operator: -=

Example: x -= 3

Equivalent to: x = x - 3

Try it:

x = 5

x -= 3

print(x)

Operator: *=

Example: x *= 3

Equivalent to: x = x * 3

Try it:

x = 5

x *= 3

print(x)

Operator: /=

Example: x /= 3

Equivalent to: x = x / 3

Try it:

x = 5

x /= 3

print(x)

Operator: %=

Example: x %= 3

Equivalent to: x = x % 3

Try it:

x = 5

x%=3

print(x)

Operator: //=

Example: x //= 3

Equivalent to: x = x // 3

Try it:

x = 5

x//=3

print(x)

Operator: **=

Example: x **= 3

Equivalent to: x = x ** 3

Try it:

x = 5

x **= 3

print(x)

Operator: &=

Example: x &= 3

Equivalent to: x = x & 3

Try:

x = 5

x &= 3

print(x)

##Operator : |=

Example: x |= 3

is equivalent to: x = x | 3

Try it:

x = 5

x |= 3

print(x)

Operator: ^=

Example: x ^= 3

Equivalent to: x = x ^ 3

Try it:

x = 5

x ^= 3

print(x)

Operator: >>=

Example: x >>= 3

Equivalent to: x = x >> ; 3

Try it:

x = 5

x >>= 3

print(x)

##Operator: <<=

实例：x <<= 3

等同于： x = x << 3

试一试：

x = 5

x <<= 3

print(x)
