How to use not equal operator in python.

Use !=. Refer to the comparison operators. To assess object identities, you may utilize the keyword is along with its negation, is not.

e.g.

1 == 1 #  -> True  1 != 1 #  -> False  [] is [] #-> False (distinct objects)  a = b = []; a is b # -> True (same object)  

In Python, the "!=" operator and the "is not" expression can be utilized to perform a not equal operation. The "!=" operator returns True when the values of the two operands on either side are not equal; otherwise, it returns False. Python is dynamically typed yet strongly typed, which means that unlike statically typed languages, it does not raise errors when comparing different data types. Consequently, if two variables hold the same value but are of different types, the not equal operator will yield True.

str = 'halo'
if str == 'halo':# equal

print ("halo")
elif str != 'halo':# not equal
print ("no halo")

We can use Python not equal operator with f-strings too if you are using Python 3.6 or higher version.

x = 10  y = 10  z = 20    print(f'x is not equal to y = {x!=y}')    flag = x != z  print(f'x is not equal to z = {flag}')    # python is strongly typed language  s = '10'  print(f'x is not equal to s = {x!=s}')  

Output:

x is not equal to y = False

x is not equal to z = True

x is not equal to s = True

Hope it helps!!

Returns True if the values on either side of the operator are unequal; otherwise, it returns False.

Syntax

3 != 2  True

The != operator in Python signifies "not equal to." It yields True when the operands on either side differ; conversely, it returns False when they are equal. In contrast, the is not operator determines whether the id() of two objects is identical. If the ids are the same, it returns False; if they differ, it returns True. Additionally, the And is not operator returns True when the operands on either side are not equal; otherwise, it returns False.

To determine whether two operands are not equal, the != operator should be utilized. When both operands possess identical values, the != operator will yield a result of False. Conversely, if the operands have different values, the not equal operator will return True. Below is an example demonstrating the comparison of variables containing integer values using the not equal operator.

#Use of operator not equal to  a= "3"  b= "4"  c = "4"  #If a is not equal to b then conditon will print true  print("a=",a,"b=",b,"\nResult of Not Equal to Operator is ",a!=b)  print("\n")  #if c equal to b then condition will print false as we are using not equal to operator  print(" b=",b,"c=",c,"\nResult of Not Equal to Operator is  ",b!=c)  print("\n")

Output of above code is

a= 3 b= 4   Result of Not Equal to Operator is  True     b= 4 c= 4   Result of Not Equal to Operator is   False
