Making Decisions Using The Relational Operators On Python 2.7.15 In Windows 10 And Mac OS X - Easy #18

Python Relational and Logical Operators

Relation and Logic are the fundamental bricks of a program that defines its functionality. With these fundamentals, you decide what should be the flow of execution and what conditions should be kept to make sure the flow stays that way.

In every programming language including python, to manage the flow of any program, conditions are required, and to define those conditions, relational and logical operators are required.

Remember those days when your mathematics teacher in school used to ask you if 3 is greater than 2, say yes, otherwise no, that is pretty much what we do in programming world too.

You provide the compiler with some condition based on an expression, compiler computes the expression and executes the condition based on the output of the expression. In the case of relational and logical expressions, the answer will always be either True or False.

Operators are the conventional symbols, that bring one, two or more operands together to form an expression. Operators and operands are two key deciding factors of the output.

Now let's see some operators that are available in python language.

Python Relational Operator

Relational operators are used to establish some sort of relationship between the two operands. Some of the relevant examples could be less than, greater than or equal to operators. Python language is capable of understanding these types of operators and accordingly return the output, which can be either True or False.

The list of operators available includes:

Less than
Greater than
Equal to
Not equal to
Less than or equal to
Greater than or equal to

Python is a general-purpose interpreted, interactive, object-oriented and high-level programming language. Python was created by Guido van Rossum in the late eighties and early nineties. Like Perl, Python source code is also now available under the GNU General Public License (GPL).

Python is a high-level, interpreted, interactive and object-oriented scripting language. Python was designed to be highly readable which uses English keywords frequently where as other languages use punctuation and it has fewer syntactical constructions than other languages.

Easy-to-learn: Python has relatively few keywords, simple structure, and a clearly defined syntax. This allows the student to pick up the language in a relatively short period of time.
Easy-to-read: Python code is much more clearly defined and visible to the eyes.
Easy-to-maintain: Python's success is that its source code is fairly easy-to-maintain.
