| Basic code? |
In this lesson, I bring together the few basics discussed in the previous videos and this video. To do this I will discuss one more important principle in programming and that is:
Datatypes
I have already introduced some data types like strings, integers, and floats. But there are more types you need to know about before we can continue.
Lists
A built-in Python sequence. Despite its name it is more akin to an array in other languages than to a linked list since access to elements are O(1).

Dicts
An associative array, where arbitrary keys are mapped to values. The keys can be any object with __hash__() function and __eq__() methods. Called a hash in Perl.
https://docs.python.org/3.1/glossary.html#term-dictionary
Tuples
tuple is an immutable sequence type, as documented in Sequence Types โ str, bytes, bytearray, list, tuple, range.
https://docs.python.org/3.1/library/functions.html#tuple
These were the very basics in programming with Python. This course continues with 5 more modules where you will learn about:
- Modules
- Flow control
- Loops
And will end with a practical application using Python to harvest data from the web.
I have placed all the videos in a playlist, which you can find here. Alternatively, you can watch the playlist below.
