This course provides a quick Python overview. It is for experienced programmers looking for key Python essentials to get productive quickly.

The aim of this mini-course is to give experienced developers a clear and concise overview of the Python language, so they can understand and write Python code in as short a time as possible. There are many Python books, courses, and tutorials out there, but this one is different in a way that it provides only the bare minimum information to be productive, thereby making use of your existing programming knowledge and not wasting your time with unnecessary background information.

If you want to learn Python quickly, this is the course for you.

Python Quickstart for Experienced Programmers

Everything in Python is an object.

For example, if we use the `type()` function introduced earlier, we can see:

print(type('hello'))    # outputs <class 'str'>

So, `hello` is an instance of the `str` class. We can use the built-in `dir()` function to list the methods and attributes of a class:

We can see that `str` has a large number of methods. For example, we can capitalise a string by calling its `capitalize()` method:
