My init.sage
is as follows. It is run at the start of each Sage REPL session.
### Set colors depending on terminal background color
# Set color -- valid schemes: 'NoColor', 'Linux', 'LightBG', Neutral', ''
%colors Linux
### Custom banner, displays even when starting Sage in quiet mode with `sage -q`
print("\n# SageMath {}, released {}, based on Python {}.{}.{}."
.format(sage.version.version, sage.version.date, *sys.version_info[:3]))
print("""
sage: %colors Linux
""")
It includes two commands that print things out, and that works fine.
Beware that print
is a function in Python 3, while it was a statement in Python 2.
So make sure you use print(...)
rather than print ...
.

I'm not sure whether init.sage
is executed when starting a Jupyter worksheet
with the SageMath kernel; and if it is, I'm not sure where things are printed to;
any print statements might be lost.
As a workaround, you could execute the following in the first cell of your Jupyter sheets:
load(sage.env.SAGE_STARTUP_FILE)
