• The uncompromising Python code formatter https://black.readthedocs.io/en/stable/ and on Github: https://github.com/psf/black

• Basics of Jupyter notebooks (on packtpub.com)
• Max Melnick's Jupyter Python Notebook Keyboard Shortcuts and Text Snippets for Beginners
• Jupyter notebooks documentation
• Matplotlib colormaps and how to normalise a colormap

• Decode URLs using Python

• # py3
  from urllib import parse
  parse.unquote("""TheURLString""")
  # or in py2.7
  import urllib
  urllib.unquote("theURL").decode('utf8')

• Translate coordinate reference system from *.prj files to proj4-Syntax as required by QGIS using the gdal python module (via GIS on Stackexchange:

• import sys
  from osgeo import osr
  prjtxt = """PROJCS["your_crs",GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["the_prj"],PARAMETER["Central_Meridian",0.0],PARAMETER["False_Easting",0.0],PARAMETER["False_Northing",0.0],PARAMETER["Latitude_Of_Origin",0.0],PARAMETER["Standard_Parallel_1",-10],PARAMETER["Standard_Parallel_2",50],UNIT["Meter",1.0],AUTHORITY["me",123456]]"""
  srs = osr.SpatialReference()
  print 'Proj4 is: %s' % srs.ExportToProj4()
  Proj4 is: <string with proj4 parameters follows>

* Invert a single column of a Pandas Dataframe: ``df.col2 = df.col2.values[::-1]`` via StackOverflow

• osgeo.ogr
• Importing modules - effbot's import confusion
• Installing a new module in Enthough Canopy Light's distro on Windows: I managed to install the DBF module by navigating to the unzipped content downloaded in the Python console. Then I just typed %run setup.py install and the compiled module is then installed in the Canopy's User\Lib\site-packages directory. Easy.
