Loops in Python

Sometimes, a specific task has to be repeated several times. In such cases, we could use loops. In Python, there are two types of loops, namely the for loop and while loop. Let's review them with specific examples.

A for loop

In Python, a for loop is used to execute a task for n times. A for loop iterates through each element of a sequence. This sequence could be a dictionary, list, or any other iterator. For example, let's discuss an example where we execute a loop:

    for i in range(0, 10): 
       print("Loop execution no: ", i)

In the preceding example, the print statement is executed 10 times:

In order to execute the print task 10 times, the range() function (https://docs.python.org/2/library/functions.html#range) was used. The range function generates a list of numbers for a start and stop values that are passed as an arguments to the function. In this case, 0 and 10 are passed as arguments to the range() function. This returns a list containing numbers from 0 to 9. The...
