Python divides the operators into the following groups:
1. Arithmetic operators
Arithmetic operators perform basic math operations like addition, subtraction, multiplication, and division.
It includes + (addition), - (subtraction), * (multiplication), / (division), % (modulo), ** (exponentiation), and // (floor division).
Example:
# Arithmetic operators
x = 10
y = 5
# Addition
print(x + y) # Output: 15
# Subtraction
print(x - y) # Output: 5
# Multiplication
print(x * y) # Output: 50
# Division
print(x / y) # Output: 2.0
# Modulo
print(x % y) # Output: 0
# Exponentiation
print(x ** y) # Output: 100000
# Floor division
print(x // y) # Output: 2
2. Comparison operators
Comparison operators are used to comparing two values and return a Boolean result indicating whether the comparison is true or false.
It includes == (equal to), != (not equal to), > (greater than), < (less than), >= (greater than or equal to), and <= (less than or equal to).
Example:
# Comparison operators
d = 10
e = 5
# Equal to
print(d == e) # Output: False
# Not equal to
print(d != e) # Output: True
# Greater than
print(d > e) # Output: True
# Less than
print(d < e) # Output: False
# Greater than or equal to
print(d >= e) # Output: True
# Less than or equal to
print(d <= e) # Output: False
3. Assignment operators
Assignment operators are used to assigning values to variables.
It includes = (assignment), += (add and assign), -= (subtract and assign), *= (multiply and assign), /= (divide and assign), %= (modulo and assign), **= (exponentiate and assign), and //= (floor divide and assign).
Example:
# Assignment operators
a = 10
b = 5
# Simple assignment
c = a
print(c) # Output: 10
# Add and assign
c += a
print(c) # Output: 20
# Subtract and assign
c -= a
print(c) # Output: 10
# Multiply and assign
c *= a
print(c) # Output: 100
# Divide and assign
c /= a
print(c) # Output: 10.0
# Modulo and assign
c %= a
print(c) # Output: 0.0
# Exponentiate and assign
c **= a
print(c) # Output: 1e+50
# Floor divide and assign
c //= a
print(c) # Output: 1
4. Logical operators
Logical operators are used to combine the results of multiple comparisons or to negate a comparison.
It includes and, or, and not.
Example:
# Logical operators
f = True
g = False
# And
print(f and g) # Output: False
# Or
print(f or g) # Output: True
# Not
print(not f) # Output: False
5. Identity operators
Identity operators are used to comparing the identity of two objects in memory.
It includes is and is not.
Example:
# Identity operators
h = [1, 2, 3]
i = [1, 2, 3]
j = h
# Is
print(h is i) # Output: False
print(h is j) # Output: True
# Is not
print(h is not i) # Output: True
print(h is not j) # Output: False
6. Membership operators
Membership operators test whether a value is contained in a sequence (such as a list or string).
It includes in and not in.
Example:
# Membership operators
k = [1, 2, 3]
l = 2
m = 4
# In
print(l in k) # Output: True
print(m in k) # Output: False
# Not in
print(l not in k) # Output: False
print(m not in k) # Output: True
7. Bitwise operators
Bitwise operators are used to perform operations on the binary representations of integers.
It includes & (and), | (or), ^ (xor), ~ (not), << (left shift), and >> (right shift).
Example:
# Bitwise operators
n = 10 # 1010 in binary
o = 4 # 0100 in binary
# And
print(n & o) # Output: 0
# Or
print(n | o) # Output: 14
# Xor
print(n ^ o) # Output: 14
# Not
print(~n) # Output: -11
# Left shift
print(n << 1) # Output: 20
# Right shift
print(n >> 1) # Output: 5
