Before we wrap up, let’s put your knowledge of Python for loop to the test! Can you solve the following challenge? Challenge: Write a function to calculate the factorial of a number. The factorial of a non-negative integer n is the product of all positive integers less than or equal...
What is an example of a for loop? An example of a for loop is: for i in range(0,10,2): This is in this for loop: print("i is now", i) The condition of the loop is "for i set to 0, every time i is less than 10, add 2 to i." This will print out: i is...
Definite Iteration: When we know how many times we wanted to run a loop, then we use count-controlled loops such as for loops. It is also known as definite iteration. For example, Calculate the percentage of 50 students. here we know we need to iterate a loop 50 times (1 iteration fo...

The loop continues to run while i is less than 5. The code block prints out the new value of the iterator each time it runs. File: loop1.py 1 2 3 for i in range(5): print("The value of i is", i) print("The loop has ended.") python3 loop1.py The value of i is 0...
For every time the while loop runs, the value of the counter is increased by 2. The loop will run as long as the variable counter is less or equal with 100. counter = 0 while counter <= 100: print counter counter = counter + 2 ...

Now, there is another interesting difference between a for loop and a while loop. A for loop is faster than a while loop. To understand this you have to look into the example below. import timeit # A for loop example def for_loop(): for number in range(10000) : # Execute the below...
Python has two kinds of loops; awhileloop, and aforloop. This page explains thewhileloop. We'll get to theforloopnext. In a way,whileloops are kind of similar toifstatements, in that they only do something if a certain condition is true. But the difference is, if the condition is ...
