Relational operators:
< Less Than
> Greater Than
== Equal To
<= Less than or equal to
>= Greater Than or equal to
!= not equal to
These operators return a boolean value true or false. They report on the relationship of the two values that surround them.
For instance:
5 < 8 returns True
99 < 12 returns False
These statements can be used in the control expression of an if statement:
if 5 < 6:
print("5 is less than 6")
That's not a great example because the answer is obvious. It's much more useful when you have a value you don't know such as user input:
age=input("Enter your age:")
age=int(age)
if age<21:
print("No drinking for you!")
or something like that.
You can combine relational operators with boolean or logic operators:
and, or, not
These operators take boolean values and report on their relationship.
For instance,
5 < 2 or 5 > 1
returns True because one of the two statements is true.
not ( 2 < 5 and 7 < 10 )
returns False because the not negates the result of the and...
