Next Step after Learning the Basics of Python Programming

Hello there,

Today I want to share with you things you could do after completing the fundamentals in Python. There is always this dilemma on what NEXT after learning and completing the basic fundamentals of Python Programming.

I will attempt to solve this using my experience after being in similar situation few years ago.

Shortest Solution

The shortest answer will be that: its depend on what you want to use python for, learn related libraries in that niche. For example, if your in the Geospatial/GIS industry then go ahead and search PyPI for related libraries and learn them.

Long Solution

Now its time to program something useful to you in Python and put that theoretical knowledge to accomplishing something practical!

Pick any topic that interests you and learn the libraries related to it. There are many tutorials and documentation out for just about any library you wish to learn.

As you go through tutorial or documentation with code in it, type in all of the code and make it work. That's how I do it. That's how every programmer does it.

Find a project that interests you and try to solve it using Python. It could be in any of the following fields:-

~ Web and Internet Development
~ Scientific and Numeric
~ Education
~ Desktop GUIs
~ Software Development
~ Business Applications

Python Project Ideas

Here you will find list of practical projects to try out. 

Reading JSON file into Pandas DataFrame

I wanted to read in a JSON object on a python pandas dataframe for further processing. So, I tried the default pandas read JSON method: read_json('file.json'), but I got just the JSON strings returned in the dataframes's row as seen below. That isn't what I was expecting....

Fortunately for me, pandas has a solution for this in its json_normalize class that “Normalize” semi-structured JSON data into a flat table.

So, I read the JSON file and applied the "json_normalize()" class and boom my semi-structured JSON data was converted into a flat table as seen above.

That was it!

Convert Projected coordinates (Northings/Eastings) to Geographical (Latitude/Longitude) using Python

Generally, there are two types of coordinate systems used to represent Geospatial data namely:-
1) Geographical Coordinate Systems - Polar coordinates assumes the earth is spheroid/geoid/ellipsoid/curve (Latitude/Longitude). Example: World Geodetic System (WGS) 1984. Geographic coordinate systems are based on a spheroid and utilize angular units (degrees).

2) Projected Coordinate Systems - Rectangular coordinates assumes the earth is flat (Northings/Eastings).Example: Universal Transverse Mercator (UTM) Zone 33. Projected coordinate systems are based on a plane (the spheroid projected onto a 2D surface) and utilize linear units (feet and meters)

Web Mapping - case study of Ahmadu Bello University (ABU) Zaria Main Campus (Samaru, Sabo LGA Kaduna State)

Hello there,

In today's post, I will share how to produce a Campus Web Map using free and open source tools.

I will use ABU Zaria as an example. Let's get started....

You need the vector (shapefile) map of the campus. If you don't have one, you can easily obtain a copy from the ABU GIS unit or you can digitize your copy from available google earth satellite image.

You can use any GIS software for this... here I use a free software called QGIS.

There are several free and open source methods of deploying the shapefile map to the web. Some notable method am going to discuss in few moment include:-
1) Google Map Engine
2) QGIS2Web plugin
3) Open Street Map
4) Python Folium Library

Choose any of the methods above to create your web map (there are many guide and tutorials on the internet or contact me for help).

Happy mapping.
