Let's get our toes wet with the basics: returns, colons, brackets, ranges, for loops and assignment.
The last line of a function is its return value, so there's no return. There's no colon after the def either: there are no colons anywhere in pydsa, blocks are indentation only.

Example

Printssq(7)
Your pydsa runs on this input and has to print the same thing as the python.
Input
(nothing)
Prints
