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('')

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 "),
