Problems with Python syntax

I am a more or less skilled Python user in Maya for quite some time and wanted to look into Python within Blender (Version: 2.79).

This is my code:

def posRotSclObj():
sel = bpy.context.selected_objects
sel2 = sel[0]
sel1 = sel[1]
print(sel1)
print(sel2)

pos1 = sel1.location
rot1 = sel1.rotation_euler
scl1 = sel1.scale
print (scl1)

pos2 = sel2.delta_location

sel2.location = (pos1[0], pos1[1], pos1[2])
sel2.rotation_euler = (rot1[0], rot1[1], rot1[2])
sel2.scale = (scl1[0], scl1[1], scl1[2])

posRotSclObj()

I have 3 problems right now:

1. When I define my selection by sel = bpy.context.selected_objects then sel[0] is the second object I have selected and sel[1] the first...that's pretty counterintuitive, especially because it was the other way around in Maya. Is this right?

2. print sel would work in Maya but Blender needs brackets around my variable: print (sel). Why is there difference in syntax?

3. When I indent beginning from the line after def except for the last where I call my function and paste it into the python console within Blender it gives me indentation errors on every line that has one indent.
