Program to create a library management system using a function

by

In this python function program, we will create a library management system using a function.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function library.
  2. Use the def keyword to define the function.
  3. Pass two parameters i.e. book name and customers name.
  4. Print the book name and customer name.
  5. Pass the book name and customer name to the function while calling the function.
				
					def library(bname,cname):
    print("Book name: ",bname)
    print("Borrowed by :",cname)
library("Harry potter","Atharv")

Output :

				
					Book name:  Harry potter

by

In this python function program, we will reverse an integer using a function.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function reverse.
  2. Use the def keyword to define the function.
  3. Take a number as input through the user and create a variable rev and assign its value equal to 0.

Python function program to get a list of odd numbers from 1 to 100

by

In this python function program, we will create a function to get a list of odd numbers from 1 to 100.

Odd number:
Odd numbers are those numbers that cannot be divided into two equal parts.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function odd.
  2. Use the def keyword to define the function.
  3. Pass two parameter i.e. starting and ending numbers.
  4. Use for loop with the range function to iterate over values between 1-100.
  5. If a number is an odd number i.e. not divisible by 2 then print the number.
  6. Pass the starting and ending numbers to the function while calling the function.
				
					def odd(lower,upper):
    print("Odd numbers between", lower, "and", upper, "are:")

    for num in range(lower, upper + 1):
        if num%2 != 0:
            print(num,end=" ")
odd(1,100)

Program to get a list of prime numbers from 1 to 100

by

In this python function program, we will create a function to get a list of prime numbers from 1 to 100.

Prime Number: A prime number is a whole number greater than 1 that cannot be exactly divided by any whole number other than itself and 1.

What is Function?
It is a block of code that executes when it is called.
To create a function use def keyword.

Steps to solve the program
  1. Create a function prime.
  2. Use the def keyword to define the function.
  3. Pass two parameters i.e. starting and ending numbers.
  4. Create a variable and assign its value equal to 0.
    If a number is divisible by 1 and by itself then it is a prime number.
  5. Use for loop with the range function to check whether a number is a prime number or not.
  6. Add only those numbers to the variable.
  7. Print the output.
  8. Pass the starting and ending numbers to the function while calling the function.
				
					def prime(lower,upper):
    print("Prime numbers between", lower, "and", upper, "are:")

    for num in range(lower, upper + 1):
        count = 0
        for i in range(1,num+1):
            if num%i == 0:
                count += 1
        if count == 2:
