          In this post, we are going to discuss how to write a python program to print the prime numbers less than an inputted number. We already posted a how-to check whether the inputted number is prime or composite.  I highly recommend reading that and come here by clicking the link below. Link to the post :  https://codicaly.blogspot.com/2021/04/python-program-to-find-given-number-is.html What is a Prime or Composite number ? A prime number is a number that has only two factors i.e, 1, and the number itself.  A composite number is a number that has more than two factors. A number is said to factor that when it divides the other number it leaves no remainder.  Generally, the factors lie between 1 and the number itself. Pre-requisites : Python Basics List Concept Conditional statements ( Nested for-loop ) Program : u=int(input('Enter the upper limit')) for i in range(2,u+1):#Primary for loop     l=[]     for j in range(1...

  In this post, we are going to check whether an inputted string is a Palindrome or not. What is Palindrome ?               A Palindrome  is a word, number, phrase, or other sequence of characters that reads the same backward as forward, such as madam or racecar. That means if the reverse of the inputted string is the same as that of the original, it is Palindrome otherwise not. Pre-requisites : Python Basics Strings concept Conditional statements. Program : a=input('Enter the phrase : ') reverse=a[::-1] if (reverse==a):     print(a,'is a pallindrome') else:     print(a,'is not a pallindrome') Explanation : 1. First we need to input the word for which we need to check it is a Palindrome or not. Using the input function we are inputting the phrase. Here we are not specifying anything before input like int or float. Hence it would take as a string that is the default. 2. To check we need to compare the reverse of the phr...
