Concept explainers

Types of Loop
Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.
Loops
Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements ca…
While Loop
Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.
Question

write in python. must use while loop

Question 4: Palindromes Filename: is_palindrome.py Write a function called is_palindrome that accepts a string and returns whether or not it is a palindrome. A palindrome is a word, phrase, or sequence that reads the same backward as forward. "madam", "racecar", "a", and "123454321" are all examples. Hint: Consider how you would use indices to compare the first character with the last. Write a main() function in your file to exercise your function to show that it works correctly. Your test implementation should not rely on visual inspection to determine if the tests pass.
