I wanna use print, but I want it to skip the new line. In Python 3 you should be able to use print(".",end=""), but it gives back: "SyntaxError: invalid syntax". What's the problem right there and is there a work arround or different funktion?
print("Def: R ",end = "")
if str(p) is not None:
print \ {',', '.join([str(p) for p in pol]),'}'
Sage uses Python 2.7. You can add a comma at the end of your print statement to avoid a newline.
However you will still get a space:
sage: for a in [1, 2, 3]: print a,
1 2 3
One workaround is to build a string incrementally, and only print it when it's done.
sage: s = ''
sage: for a in [1, 2, 3]: s += str(a)
sage: print s

For other workarounds, searching the web for "python print without newline or space" yields a number of results among which:
In particular you can get the Python3-like print function:
sage: from __future__ import print_function
sage: for a in [1, 2, 3]:
....: print(a, end='')
....: print('')
123
Note: the migration of SageMath to Python 3 is tracked here:
You can just add a comma after the print command:
sage: print("Def: R "),
