👉Python Not Equal Operator (!=)
Python Not Equal Operator : The Python Not Equal Operator (!=) is used to compare two values and returns True if the values are different; otherwise, it returns False. Python’s flexibility and dynamic nature make it a powerful language for handling various data types and conditions using this operator.
👉Types of Not Equal Operators in Python
Python Not Equal Operator
Python supports two types of Not Equal operators:
- != — Used in Python 2 and Python 3.
- <> — Used only in Python 2 (deprecated in Python 3).
👉Syntax
- X != Y — Recommended syntax for Python 3.
- X <> Y — Outdated syntax for Python 2.
👉Examples of Python Not Equal Operator
👉Example 1: Same Data Type but Different Values
python
A = 44
B = 284
C = 284
print(B != A) # Output: True
print(B != C) # Output: False
👉Example 2: Different Data Types but Same Values
python
C = 12222
X = 12222.0
Y = “12222”
print(C != X) # Output: False
print(X != Y) # Output: True
print(C != Y) # Output: True
👉Using Not Equal Operator with if Statement
The if statement can check conditions using the != operator.
👉Example:
python
X = 5
Y = 5
if X != Y:
print(“X is not equal to Y”)
else:
print(“X is equal to Y”)
Output: X is equal to Y
👉Using == Operator with while Loop
The == operator can be combined with a while loop to iterate as long as a condition is true.
👉Example:
python
m = 300
while m <= 305:
m += 1
if m % 2 == 0:
continue
print(m)
👉Output:
301
303
305
👉Using Not Equal Operator with while Loop
The != operator can also be combined with a while loop to filter certain conditions.
👉Example:
python
m = 300
while m <= 305:
m += 1
if m % 2 != 0:
continue
print(m)
👉Output:
302
304
306
👉Using Not Equal Operator with Custom Objects
Python allows developers to define custom conditions using the __ne__ method.
👉Example:
python
class G9Example:
s_n = ”
def __init__(self, name):
self.s_n = name
def __ne__(self, x):
if type(x) != type(self):
return True
if self.s_n != x.s_n:
return True
else:
return False
G1 = G9Example(“Software Moji Moji”)
G2 = G9Example(“HipHop Moji”)
G3 = G9Example(“Software Moji Moji”)
print(G1 != G2) # Output: True
print(G2 != G3) # Output: True
print(G1 != G3) # Output: False
👉Comparison Operators in Python
| Operator | Description | Example |
| != | Not equal to | A != B |
| == | Equal to | A == B |
| >= | Greater than or equal to | A >= B |
| <= | Less than or equal to | A <= B |
| > | Greater than | A > B |
| < | Less than | A < B |
👉Useful Tips for Using Not Equal Operator
✅ Use != for better compatibility in Python 3.
✅ Avoid <> as it is deprecated in Python 3.
✅ In formatted strings, ensure you use != and not ≠, which may appear in certain fonts or editors.
✅ The != operator is powerful for filtering data conditions, especially in dynamic data types.
