Relational operators check the relationship between two operands. They return true if the comparison or relation is true otherwise it will return false.
There are six comparison operators in the Python programming language. They are:
Equal To
Not Equal To
Greater Than
Less Than
Greater Than or Equal To
Less Than or Equal To
Equal To (==)
The equal to operator is represented by the double equal sign (==) in the Python programming language. The single equal sign (=) is used for assignment in the Python programming language.
The equal to symbol checks if two operands are equal.
Not Equal To (!=)
This is the opposite of the equal to symbol. It checks if the two operands are not equal.
Greater Than (>)
This checks if the left operand is greater than the right operand.
Less Than (<)
The less than operator is the opposite of the greater than operator. It checks if the operand on the left is less than the operand on the right.
Greater Than or Equal To (>=)
Checks if the left hand operand is either greater or equal to the right hand operand.
Less Than or Equal To (<=)
Checks if the left hand operand is either less or equal to the right hand operand.
Relational operators allow the programmer to define conditions in their code based on the relationship between two variables.
Every single time you are filled with techno-optimism in Nigeria, there comes a government policy to put a lid on it.
In Nigeria, the prevailing rule is that whatever they cannot own or control, the government will seek to destroy.
Today, the government through the CBN struck another area of the economy by banning the purchase of cryptocurrencies using the banks.
To be honest, it was inevitable as cryptocurrencies where used in funding the EndSARS protests that held in the country last year.
This might slow down adoption of cryptocurrencies but it will not end them. They alternative is to go peer to peer the way it was always intended for cryptocurrencies.
The default mode of execution of a program is from top to bottom. However in the course of the execution of a program, the Python interpreter comes across some statements that change the default mode of execution.
Such statements are called a branch. A branch is an instruction in a computer program that causes a computer to begin executing a different instruction sequence and thus deviate from its default behaviour of executing instructions in order.
Branching is implemented as a series of control statements in high level programming languages. In the Python programming language, these include:
IF Statement
WHILE Loop
FOR Loop
IF Statement
If-Then-Else flow diagram
The IF Statement works by evaluating a programmer specified boolean condition and checking if it evaluates to true or false.
If the condition evaluates to true, certain actions are carried out. An evaluation to false means that alternate actions are carried out.
WHILE Loop
While loop flow diagram
A loop ensures that code is repeated. However in programming when you want ensure that you loop an infinite number of times, you use a WHILE loop.
The WHILE loop consists of a block of code and a condition/expression. The condition/expression is evaluated, and if the condition/expression is true, the code within all of their following in the block is executed. This repeats until the condition/expression becomes false.
In the Python programming language, the WHILE loop has an ELSE branch just like the IF statement.
FOR Loop
For loop flow diagram
When you want to loop a fixed number of times in the Python programming language, you use a FOR loop.
A FOR loop has two parts: a header specifying the iteration, and a body which is executed once per iteration. The header often declares an explicit loop counter or loop variable, which allows the body to know which iteration is being executed. FOR loops are typically used when the number of iterations is known before entering the loop.
Conclusion
Branching statements allow the flow of execution to jump to a different part of the program.
Mastering them is important in the journey of learning how to program.
