I'll check if I understand it, thanks :D. I just recently started to be 
interested in Python (mainly because of GDAL) but I haven't gotten very 
far with learning it yet. That's why I'm still scripting mainly in bash.

Cool! I got the download, mosaic-ing and such figured out pretty good 
with the sentinelsat script 
(https://github.com/sentinelsat/sentinelsat). But I'll definitely have a 
look once I get far enough in Python to migrate my bash script. As for 
SNAP, It's a nice tool once you figured it out but it's pretty huge to 
be used just as a library to be called from something else. It's also a 
little picky about the JVM. I also find GDAL to be more performant - on 
my machines, at least.
