Comparison Operators in Python

In the realm of Python, comparison operators play a pivotal role, allowing us to juxtapose two values and yield a boolean outcome (`True` or `False`) contingent on the comparison's result.

Here's a succinct breakdown of the comparison operators at your disposal in Python:

Operator Description Example
== Is equal to a==b
!= Is not equal to a!=b
< Is less than a<b
> Is greater than a>b
<= Is less than or equal to a<=b
>= Is greater than or equal to a>=b

These tools are frequently employed within `if` statements and during the execution of `while` loops.

To better illustrate their application, consider this example.

Let's initialize two variables, "x" and "y", with the values:

x=2
y=3

Exploring the behavior of various comparison operators:

The '==' operator probes for equality between two values:

print(x==y)

This evaluates to False, given that 2 doesn't match 3.

False

The '!=' operator, on the other hand, investigates disparities:

print(x!=y)

This evaluates to True, underscoring the difference between 2 and 3.

True

The '>' operator assesses if the left-hand value surpasses the right:

print(x>y)

Given that 2 doesn't exceed 3, this returns False.

False

Conversely, the '<' operator determines if the left-hand value is overshadowed by the right:

print(x<y)

This rings true, as 2 is indeed less than 3.

True

The '>=' operator weighs whether the left-hand value is either greater than or on par with the right:

print(x>=y)

This returns False, as 2 neither exceeds nor equals 3.

False

The '<=' operator gauges if the left-hand value is either inferior to or matches the right:

print(x<=y)

Given that 2 is less than 3, this is validated as True.

True

A unique facet of Python is its ability to concatenate comparison operators, streamlining the comparison process. For instance, to ascertain if `x` lies exclusively between 0 and 10, you'd express it as 0<x<10.

print(0<x<10)

This construct confirms True if `x` is nestled between 0 and 10. Otherwise, it's False. In our scenario, with x=2, the statement 0<2<10 is undeniably true.

True

Armed with this insight, you're now well-equipped with a thorough understanding of Python's comparison operators, ready to harness their capabilities to the fullest.
