x is not y |
| Membership Operators |
| Operator |
Description |
Example |
Result |
| is |
Evaluates if a value is present in a sequence (list, tuple, string, etc.) |
5 in [1, 2, 3] |
False |
| is not |
Evaluates if a value is not present in a sequence |
5 not in [1, 2, 3] |
True |
• Utilizes various Python operators:
py Copy Code
# Arithmetic operators example
x = 10
y = 5
print("Arithmetic Operators Example:")
print("Addition:", x + y)
print("Subtraction:", x - y)
print("Multiplication:", x * y)
print("Division:", x / y)
print("Modulus:", x % y)
print("Exponentiation:", x ** y)
print()
# Comparison operators example
a = 10
b = 20
print("Comparison Operators Example:")
print("Greater than:", a > b)
print("Less than:", a < b)
print("Equal to:", a == b)
print()
# Logical operators example
c = True
d = False
print("Logical Operators Example:")
print("Logical AND:", c and d)
print("Logical OR:", c or d)
print("Logical NOT:", not c)
print()
# Bitwise operators example
e = 5
f = 3
print("Bitwise Operators Example:")
print("Bitwise AND:", e & f)
print("Bitwise OR:", e | f)
print("Bitwise XOR:", e ^ f)
print("Bitwise NOT:", ~e)
print("Left shift:", e << 1)
print("Right shift:", e >> 1)
print()
# Identity operators example
g = [1, 2, 3]
h = [1, 2, 3]
print("Identity Operators Example:")
print("Identity:", g is h)
print("Not Identity:", g is not h)
print()
# Membership operators example
i = 2
j = [1, 2, 3]
print("Membership Operators Example:")
print("Membership:", i in j)
print("Not Membership:", i not in j)
