Carriage return '\r' stops working when pwntools are imported in python3

I have this little method to print overlapping strings of 80 characters:

def print80(s):
    pad = ' '*(80-len(s))
    print((s+pad)[:80], end='\r')

It works well, but if I import pwntools, for example with import pwn, it stops working: the \r character is no longer printed.
