Welcome officially to the third section. And now
the fun really begins. Now we're starting to take
a sort of a deeper
step or a bigger step into the world of Python programming
because here we're going to be talking about control flow
and loops.
Now. So far in the previous two sections, we've talked about strings and integers
and the programs have been pretty for the most part basic, right?
You can either maybe have an input or we provide
ourselves with some string and integers and then we say,
OK, I'm going to do this and do this and do that and then simply print, right?
But now with control flow and loops,
what if we wanted to say? OK?
If something is this,
then let us do that.
But if something isn't this thing, let us do something else.
This is control flow and loops. Also.
What if, for example, we had like a list,
OK? It could be a list of names, a list of books, a list of passwords, right?
And then we wanted to go through each password in that list
and do something,
right?
Maybe we wanted to take each password and encrypt them,
or maybe we want to take each password and then
check to see if the password is actually strong or weak
depending on several kinds of conditions.
We're going to cover that in this section.
This is going to be one of the major sections in
this particular course.
And I'm really excited to teach you about control flow and loops.
Let's begin.
