# check packages in python

# the python packaging is sometimes hard to understand, in that way it often helps to see what python

# Once in a while you really would need case switching: this is how to best do it in python:

def positive_handler(x):
    print("the number {} is positive".format(x))
     
def zero_handler(x):
    print("the number {} is zero".format(x))
     
def negative_handler(x):
    print("the number {} is negative".format(x))

A good source for logging is the Hitchhikers guide to Python: http://docs.python-guide.org/en/latest/writing/logging/

In this example I will show you how to read and write yaml configuration files in python
(this is built for python 3.6, you can copy this into a Jupyter notebook and execute!)

Background Information:
-----------------------
yaml is a configuration language:
- see this link for a good introduction on what is possible with yaml: https://learnxinyminutes.com/docs/yaml/

In python you need pyyaml to write and read yaml files:
