How we can add loops in Python? | full tutorial Video

Hi friends!
Today is out topic is Loops in python that how can we add them to simplify our program and get the code shorter. Also, it is main concept of iterations.
Iteration is a repetition of a sequence of computer instructions a specified number of times or until a condition is met.
The while statement:
Computers are often used to automate repetitive tasks. Repeating identical or
similar tasks without making errors is something that computers do well and people
do poorly. Because iteration is so common, Python provides several language
features to make it easier.
One form of iteration in Python is the while statement.
Infinite loops:
An endless source of amusement for programmers is the observation that the directions on shampoo, “Lather, rinse, repeat,” are an infinite loop because there is no iteration variable telling you how many times to execute the loop. In the case of countdown, we can prove that the loop terminates because we know that the value of n is finite, and we can see that the value of n gets smaller each time through the loop, so eventually we have to get to 0. Other times a loop is obviously infinite because it has no iteration variable at all. Sometimes you don’t know it’s time to end a loop until you get half way through the body. In that case you can write an infinite loop on purpose and then use the break statement to jump out of the loop
Definite loops using for:
Sometimes we want to loop through a set of things such as a list of words, the lines in a file, or a list of numbers. When we have a list of things to loop through, we can construct a definite loop using a for statement. We call the while statement an indefinite loop because it simply loops until some condition becomes False, whereas the for loop is looping through a known set of items so it runs through as many iterations as there are items in the set.
The syntax of a for loop is similar to the while loop.
