Prime Number Program in Python

Prime Number Program in Python

Python programming language is a high-level, general-purpose programming language. It is designed in a way where code readability depends upon the effective use of indentation. Most developers accept the Python programming language. Due to its language construct and the object-oriented approach, Python allows programmers to create logical code from small to large-scale projects. This language is dynamically typed and garbage collected. It is popular because of its vast library support that enables developers to implement their tasks efficiently. Python syntax is also straightforward for the programmers to understand and accordingly implement the programs. It is often called the “batteries included” language because of its comprehensive standard library. 

Python programming language supports multiple programming paradigms: structured, object-oriented, and functional programming. Python also supports aspect programming. All these paradigms are supported through Python extensions. Python has more manageable memory management that utilizes dynamic typing, the combination of reference counting, and a cycle-detecting garbage collector. Python supports dynamic name resolution, which binds the method with the variable names for the program’s execution. Programming in Python language is found to be a lot easier because it is designed to be highly readable, and it often utilizes English keywords, which in the case of other languages is not the same. They use punctuations for their syntax. You will find fewer syntactic constructions in Python than in other programming languages.

Python is made as a compulsory programming language taught to the students as it is highly used and has easily understandable syntax. By learning Python, you will be preparing yourself to become a better software engineer in the near future. Advantageous key points that encourage many to learn Python are:

• It is interpreted. The Python programs are processed at runtime by the interpreter, because of which you don’t need to compile your program before executing it.

• It is interactive. You can directly interact with the interpretation through Python prompt and directly write your programs.

• It is supportive of object-oriented programming technique that encapsulates code within the objects.

• Python is highly considered as the Beginner’s language. It is a good option for beginner-level programmers to learn programming due to its easy-to-understand syntax. 

Python is an easy-to-learn language. It is simple to read and easy to maintain. It has a broad standard library that allows for the development of more advanced applications. Python supports interactive mode, allowing developers to conduct interactive testing and debug the code snippets. Python is a portable and extendable programming language. Python is also seen providing the major commercial databases. Python programming supports GUI applications. Python supports scalability with its better structure and supports large programs than shell scripting. All these are the applications of the Python programming language. 

Variables in Python are the reserved memory locations that store values. This implies that it has some space in the memory whenever you initiate a variable. Based on the variable’s data type, the memory is allocated by the interpreter. Thus, through different data types of the variables, you will be able to store various values like integers, decimals, or characters in these variables. Examples of assigning values to variables are: count = 10 => this is an integer assignment, miles = 100.6 => this is a floating-point assignment, and name = “Python”   => this is a string assignment. You can also provide a single value to the several variables at once as Python supports Multiple assignments. For example, a = b = c =5. Python has five standard data types. They are Numbers, String, List, Tuple, Dictionary. These Python data types define the operations that can be performed on them and the storage method implied on them.  

Python language supports various types of operators like Arithmetic operator, Comparison (Relational) operator, Assignment operator, Logical operator, Bitwise operator, Membership operator, and Identity operator. Python programming language also supports decision-making statements, including if, if-else, and nested if. Python also supports loop statements that allow you to execute a statement or a group of statements multiple times. There are several types of loops introduced in Python for handling the looping requirements those are,

• While loop : While the condition mentioned is true, the loop repeats the execution of the statement or the group of statements. The conditions are checked before executing the loop body.

• For loop : For loop executes a sequence of statements various times and abbreviates the code snippet that manages the loop variable.

• Nested loops : Nested loops indicate that one loop can be nested with multiple other loops.

Below is an example of implementing the Prime Number Program in Python. 

The program is to check whether the number given is a prime number or not.

number = int(input(“enter a number: “)) # this is to get input from the user

# if you wish to assign the value in the program then do it as follow

# number = (any number that you wish to assign)

if number > 1: # because prime numbers are greater than 1

for I in range(2, number):

if (number % i) == 0:

print(number, “is not a prime number”)

print(i, “times”, number//i, “is”, number)

else:

print(number, “is a prime number”)

# condition for the input value less than or equal to 1

else:

print(number, “is not a prime number”)
