Example: Print Multiplication table of a first 5 numbers using for loop and while loop In this program, we iterate the first five numbers one by one using the outer loop and range function Next, in each iteration of the outer loop, we will use the inner while loop to print the multiplic...

This exercisecontains 22 different coding questions, programs, and challenges to solveusing if-else conditions,forloops, therange()function, andwhileloops. Topics:Control flow statements,Loop, andwhile loop Python Functions Exercise Practice how to create a function, nested functions, and use the fun...
The while loop runs as long as the expression (condition) evaluates to True and execute the program block. The condition is checked every time at the beginning of the loop and the first time when the expression evaluates to False, the loop stops without executing any remaining statement(s). ...

☼ Write aforloop to print out the characters of a string, one per line. ☼ What is the difference between callingspliton a string with no argument or with' 'as the argument, e.g.sent.split()versussent.split(' ')? What happens when the string being split contains tab characters, ...
You’ll begin by digging into loops, a common way to avoid violating the “don’t repeat yourself” (DRY) rule of programming, as you learn how to use a for loop to iterate over the elements of a string or perform an action a certain number of times. You’ll then turn to ...
1. Make sure that you use while-loops sparingly. Usually a for-loop is better.尽量节制使用while循环,通常使用for循环会更好些。2. Review your while statements and make sure that the thing you are testing will become False at some point.检查你的while语句,确保它的确会在某些时候是“假”。3....
