Hi Patricia, for running different experiments consecutively, see Merging two experiments - you can make a batch file in Windows and that will run the .py scripts for each experiment.
For storing, sharing and running your code online - see Pavlova.org. You can download the latest PsychoPy (3.0.2) and easily upload your experiment files to Pavlovia using the Builder interface by following these instructions on the PsychoPy website.
