In Python, The while loop statement repeatedly executes a code block while a particular condition is true. We use w a while loop when number iteration is not fixed. In this section, we will see how to use a while loop inside another while loop. The syntax to write anested while loopsta...
In Python, we mostly use for loops in which we iterate over all elements of an iterable object. As it's perfectly straightforward, a single example may do.*PYTHON "FOR" LOOP EXAMPLE.begin program python3.countries = ['Netherlands','Germany','France','Belgium','Slovakia','Bulgaria','...
It’s often cleaner to break out from several different locations rather than try to specify all the termination conditions in the loop header. To see this construct in practice, consider the following infinite loop that asks the user to provide their password: Python password.py MAX_ATTEMPTS ...
But it is not considered good programming practice to use it outside the loop. This behavior might vary between different versions and releases of Python. Using the Python for Loop with Sequential Data Types The Python for loop can also be used with sequential data structures such as Strings,...

Practice Your Knowledge What are the primary uses of 'for' loops in Python according to the article from w3docs? Executing a block of code a certain number of times. Controlling the quantity of iterations. Executing a block of code non-stop and uncontrolled. Avoiding error exceptions. ...

for i in range(0,10): print i The output: Therange()method should include both an upper and lower range. In case you use only one value (say, for i in range(10)), Python will automatically assume that the count starts from 0. It is good practice to include both lower and upper...
If you’re interested in making your own iterators, I’ve also written an article onhow to make an iterator in Python. If you want an excuse to practice making iterators, consider givingPython Morselsa try. The first few exercises include an excuse to create your own Python iterator. ...
