Session I 

We learned how to make directories and new files using command lines. 
Mac OSX/Linux 
Open up your Terminal and type in the following after the $ sign. 
$ mkdir learnpython 
$ cd learnpython 
$ touch ex1.py

Windows 
mkdir learnpython 
cd learnpython 
new-item ex1.py -type file 
Pylady Komanapalli shared a cool tip on how to start your text editor and a new file from the PowerShell (this command will work only on windows)
start notepad++ ex1.py
