In this course, you will get a comprehensive overview of Python. You will start by laying the foundation and learning the introductory topics like operators, conditional statements, functions, loops, assignment statements, and more. You will then move onto more advanced topics such as classes and inheritance, iterators, list comprehensions, and dictionaries. Along with this, you will also get to explore the concept of testing and take a look at how GUI applications can be designed using Tkinter, Python's standard GUI library. 

By the time you're done, you'll be able to hit the ground running and be equipped with the tools that will allow you to be productive in Python.

Python 3: From Beginner to Advanced

# Looping over lists

If you want to do something with every element of a list, you can use a `for` loop. A simple `for` loop looks like this:
```python
for e in my_list:
 print(e)
```

If you need to work with not only the elements in the list, but also their position in the list, you can use a more complicated version of the `for` loop:
```python
for i in range(0, len(my_list)):
 print(my_list[i], "is at", i)
```

If your background is in C, C++, or Java, you may be tempted to use the more complicated version for everything. However, that's not helpful. Each version has its own uses. 

The following is an example of both of these `for` loop versions:
