How to use not equal operator in python

0 votes

How would you say does not equal?

Like

if hi == hi:
    print "hi"
elif hi (does not equal) bye:
    print "no hi"

Is there something equivalent to == that means "not equal"?

Use !=. See comparison operators. For comparing object identities, you can use the keyword isand its negation is not.

e.g.

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

You can use "!=" and "is not" for not equal operation in Python. The python != ( not equal operator ) return True, if the values of the two Python operands given on each side of the operator are not equal, otherwise false . Python is dynamically, but strongly typed , and other statically typed languages would complain about comparing different types . So if the two variables have the same values but they are of different type, then not equal operator will return 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!!

a != b Returns True if the values on either side of the operator are not equal to each other otherwise False.
Syntax 
3 != 2
True

Let’s say we have a Data class with looker fields – id and record. When we are using the not-equal operator, we just want to compare it for record value. We can achieve this by implementing our own __ne__() function.

class Data:
    id = 0
    record = ''

    def __init__(self, i, s):
        self.id = i
        self.record = s

    def __ne__(self, other):
        # return true if different types
        if type(other) != type(self):
            return True
        if self.record != other.record:
            return True
        else:
            return False

d1 = Data(1, 'Java')
d2 = Data(2, 'Java')
d3 = Data(3, 'Python')

print(d1 != d2)
print(d2 != d3)


Output:

False
True

Notice that d1 and d2 record values are same but “id” is different. If we remove __ne__() function, then the output will be like this:

True
True

The != operator in Python stands for "not equal to." If the operands on either side are not equal, it returns True;
if they are, it returns False. The is not operator, on the other hand, checks whether the id() of two objects is
 the same or not. If they are the same, it returns False; if they are not, it returns True. If the operands on either
 side are not equal, the And is not operator returns True, else it returns False.

To check if operands are not equal then use != operator.

If both operands has same value then != will return False. If both operands are different value then not equal operator will return value as True

Here is sample example of variable containing integer values and their comparison result with not equal to 

#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
