Python Operators

by

In Python, operators are symbols or keywords used to perform operations on values or variables. There are several types of operators in Python:

  1. Arithmetic operators: These are used to perform mathematical operations such as addition, subtraction, multiplication, division, modulus, exponentiation, and floor division.

Example:

a = 10
b = 5

print(a + b)   # Output: 15
print(a - b)   # Output: 5
print(a * b)   # Output: 50
print(a / b)   # Output: 2.0
print(a % b)   # Output: 0
print(a ** b)  # Output: 100000
print(a // b)  # Output: 2
  1. Comparison operators: These are used to compare two values and return a Boolean value (True or False) based on the comparison. The comparison operators include ==, !=, >, <, >=, and <=.

Example:

a = 10
b = 5

print(a == b)   # Output: False
print(a != b)   # Output: True
print(a > b)    # Output: True
print(a < b)    # Output: False
print(a >= b)   # Output: True
print(a
  1. Logical operators: These are used to combine Boolean expressions and return a Boolean value. The logical operators include and, or, and not.

Example:

a = 10
b = 5
c = 7

print(a > b and b > c)    # Output: False
print(a > b or b > c)     # Output: True
print(not(a > b))         # Output: False
  1. Assignment operators: These are used to assign values to variables. The assignment operators include =, +=, -=, *=, /=, %=, **=, and //=.

Example:

a = 10
b = 5

a += b   # Equivalent to a = a + b
print(a)  # Output: 15

a **= b  # Equivalent to a = a ** b
print(a)  # Output: 759375
  1. Identity operators: These are used to compare the memory location of two objects. The identity operators include is and is not.

Example:

a = [1, 2, 3]
b = [1, 2, 3]
c = a

print(a is b)   # Output: False
print(a is not b)   # Output: True
print(a is c)   # Output: True
  1. Membership operators: These are used to check whether a value is a member of a sequence or not. The membership operators include in and not in.

Example: Membership operators are used to test whether a value is a member of a sequence (list, tuple, set, dictionary).

in (is a member of) not in (is not a member of)

7. Identity Operators: Identity operators are used to compare the memory location of two objects.

is (is the same object as) is not (is not the same object as)
