Sorting a list in Python is very very easy.

psychedelics= []
psychedelics.append("lsd")
psychedelics.append("dmt")
psychedelics.append("thc")
 
psychedelics.sort()
 
print psychedelics

This will sort your list.

If you want to return a new list, and never change the old list you can use sorted:

psychedelics= []
psychedelics.append("lsd")
psychedelics.append("dmt")
psychedelics.append("thc")
 
sortedPsychedelics = sorted(psychedelics)
 
print sortedPsychedelics
 
print psychedelics

Simple stuff …
