What Is the Not Equal Operator?

• The not equal operator != in Python is used to check if two values are different.

How to Use It:

• The basic way to use the not equal operator is:

  python

  result = value1 != value2
  

  • value1 and value2 are the values you want to compare.
  • result will be True if the values are not equal, and False if they are equal.

Examples and Exercises:

1. Not Equal Comparison of Numbers:

   python

   a = 10
   b = 12
   c = 12
   print(a != b)  # Output: True
   print(b != c)  # Output: False
   

2. Using Not Equal Operator in an IF Statement:

   python

   a = 11
   if a % 2 != 0:
       print(a, "is not an even number.")
   

   • Output: 11 is not an even number.

3. Not Equal Operator with Strings:

   • You can also compare text.
   python

   a = "python"
   b = "javascript"
   if a != b:
       print(a, 'and', b, 'are different.')
   

   • Output: python and javascript are different.

4. Not Equal Operator in a While Loop:

   • You can use the not equal operator to control loops.
   python

   a = 4
   while a != 0:
       print("hello")
       a -= 1
   

   • Output:

      

     hello
     hello
     hello
     hello
     

5. Not Equal Operator in Compound Conditions:

   • Combine conditions using the not equal operator.
   python

   a = 4
   b = 5
   if (a == 1) != (b == 5):
       print('Hello')
   

   • Output: Hello
