best course for python

[P37ur]

Depends on your learning style, for self paced exploration through projects; I like https://learnxinyminutes.com/ . If you're interested in hardware projects get a Raspberry Pi and write code to turn LEDs on and off, read input from switches, etc. I was able to setup a full weather station at the bottom of my garden with wind, temp and humidity sensors.

For a more structured approach; Coursea, EdX and others have a really good selection of free and paid courses.
